创新的个人例子英语作文Innovation is a vital component of personal and professional growth. It enables us to adapt to changing circumstances, solve complex problems, and create new opportunities. One personal example of innovation that has had a profound impact on my life is the development of a mobile application that I created to help manage my daily tasks and improve my productivity.In today's fast-paced world, the ability to effectively manage our time and prioritize our responsibilities is crucial. As a busy student juggling coursework, extracurricular activities, and part-time employment, I often found myself feeling overwhelmed and struggling to keep track of my various commitments. Traditional to-do lists and paper-based planners were not providing the level of organization and flexibility I needed to stay on top of my tasks.Determined to find a solution, I began exploring the world of mobile applications. I was intrigued by the potential of these digital tools to streamline task management and improve productivity. After researching various task management apps, I realized that whilemany of them offered useful features, they did not fully address my specific needs and preferences.This realization sparked an idea within me. Why not create my own mobile application tailored to my personal requirements? With a background in computer science and a keen interest in software development, I decided to embark on this innovative project.The first step in my journey was to carefully analyze my daily routine and identify the pain points I was experiencing in task management.I made a list of the features and functionalities I wanted my app to have, such as the ability to set recurring tasks, organize tasks by category, and receive customizable reminders.Armed with this information, I began the process of designing and developing my own task management application. I utilized a range of programming languages and development tools to bring my vision to life, meticulously crafting each feature to ensure it aligned with my specific needs.One of the key innovations I incorporated into my app was the integration of artificial intelligence (AI) and machine learning algorithms. By analyzing my task history and patterns, the app was able to provide personalized recommendations and suggestions to help me optimize my time management. For example, the app wouldidentify recurring tasks and propose the most efficient way to schedule them, or it would suggest grouping related tasks together to streamline my workflow.Another innovative aspect of my app was the incorporation of gamification elements. I recognized that maintaining motivation and engagement with task management can be a challenge, so I designed a system of rewards and achievements to make the process more enjoyable and rewarding. Users could earn virtual badges or points for completing tasks on time, which provided a sense of accomplishment and encouraged continued use of the app.As I continued to refine and improve my application, I also focused on enhancing the user interface and overall user experience. I conducted extensive user testing, soliciting feedback from friends and family, and made iterative adjustments to ensure the app was intuitive, visually appealing, and easy to navigate.One of the most rewarding aspects of this innovative project was the positive impact it had on my own productivity and well-being. By using my custom-built task management app, I was able to streamline my daily routine, prioritize my responsibilities, and reduce the feelings of stress and overwhelm that had previously plagued me. The app's personalized features and AI-driven recommendations helped me optimize my time and focus on the tasks that trulymattered, leading to increased productivity and a greater sense of accomplishment.But the benefits of my innovative app did not stop there. As I continued to refine and improve the application, I realized that it could also be valuable to others who were facing similar challenges in task management. I decided to make the app available to the public, initially through a private beta testing phase and then as a downloadable application on various app stores.The response from users was overwhelmingly positive. Individuals from diverse backgrounds, ranging from busy professionals to students like myself, praised the app's innovative features and the positive impact it had on their productivity and overall well-being. Many users shared stories of how the app had helped them regain control of their schedules, reduce stress, and achieve a better work-life balance.The success of my task management app has not only been a personal triumph but also a testament to the power of innovation. By identifying a problem, leveraging my skills and knowledge, and taking the initiative to create a customized solution, I was able to develop an innovative tool that has had a tangible impact on the lives of others.This experience has taught me several valuable lessons about the nature of innovation. Firstly, it has shown me that innovation is not solely about creating groundbreaking new technologies or products. Sometimes, the most impactful innovations are those that address specific, personal needs and challenges. By focusing on my own struggles with task management, I was able to develop a solution that resonated with a wider audience.Secondly, this project has reinforced the importance of user-centric design and the incorporation of feedback into the innovation process. By actively engaging with users, soliciting their input, and making iterative improvements to my app, I was able to ensure that it truly met the needs and expectations of the people who would be using it.Finally, this experience has highlighted the role of perseverance and a willingness to take risks in the pursuit of innovation.

申请参加志愿者活动英语作文初中全文共3篇示例,供读者参考篇1My Dream to Become a VolunteerEver since I was a young child, I have felt a calling to help those in need. I remember watching television and feeling my heart ache at the images of people suffering from poverty, hunger, and lack of access to basic resources. Even at that young age, I knew I wanted to make a difference in this world.That desire has only grown stronger as I've gotten older and become more aware of the harsh realities faced by so many people, both in our local community and around the globe. The more I learn about issues like homelessness, lack of education, and environmental degradation, the more I feel compelled to take action.That's why I am writing this essay to apply for the volunteer program at the local community center. I firmly believe that volunteering is one of the most powerful ways an individual can create positive change. By donating our time and effort toworthy causes, we can directly improve lives and tackle some of society's greatest challenges.One issue that is particularly close to my heart is food insecurity. It is absolutely heartbreaking to me that in a world of such abundance, there are millions of children and families who don't have enough to eat. That's why I have regularly volunteered at our local food bank over the past two years, helping to sort and distribute donated food items to those in need.The sense of fulfillment I get from this work is impossible to put into words. Knowing that I am playing a small role in ensuring no child goes to bed hungry gives me a profound sense of purpose. I vividly remember the grateful smiles on people's faces as they received bags of nutritious food, and those images will stay with me forever.However, I know that food banks alone cannot solve the systemic issues that lead to hunger and poverty. That's why I'm eager to expand my volunteer efforts to include other important areas through this program. From tutoring underprivileged students to participating in environmental clean-ups, I want to impact as many lives as possible in a positive way.One area I am particularly excited about is the opportunity to work with refugee families. As someone whose own grandparents were refugees fleeing war and persecution, I have a deep appreciation for the incredible strength and resilience it takes to build a new life in an unfamiliar land. I can't imagine having to leave behind everything you know and love out of fear for your safety.If given the chance, I would love to help refugee families get settled, learn the local language and customs, and access crucial resources like education, healthcare, and employment opportunities. Having the perspectives of volunteers who can relate to their experiences could make a world of difference in easing this difficult transition.In addition to the practical support I could provide, I also feel that interacting with refugees would be an incredibly enriching experience that would broaden my own worldview. Learning about their cultures, traditions, and stories would give me a deeper appreciation for the diversity of human experience.Ultimately, my goal in seeking out these volunteer opportunities is to become a more compassionate, empathetic, and socially conscious person. I don't just want to check a box or add a line to my resume; I want these experiences tofundamentally shape who I am and how I move through the world.Volunteering teaches skills like leadership, problem-solving, and working as a team that will be invaluable in all areas of my life. But more importantly, it will instill in me a true spirit of service, generosity, and genuine concern for the welfare of others. In a world that often feels jaded and self-interested, I want to be a force for kindness and giving back.I recognize that as a middle school student, I may not have the same skills, experiences, or qualifications as an adult volunteer. However, what I may lack in those areas, I make up for in energy, idealism, and a passionate desire to learn and grow. I promise to approach every volunteer opportunity with enthusiasm, respect, and a willingness to take direction from experienced leaders.At the end of the day, I don't need recognition, accolades, or a fancy title. I just want the chance to get my hands dirty and actually make a tangible difference, no matter how small. Whether it's planting trees, tutoring children, or serving food at a shelter, I will joyfully embrace any task and pour my whole heart into it. Because that's what volunteering is all about – taking action instead of just talking about problems.Looking beyond the boundaries of my own life and cultivating a sense of empathy and compassion for others is something that is critically important to me. It's what gives me hope for the future that people truly can come together, embrace our common humanity, and work to create a better world for all. And it all starts on the individual level, with people simply caring about their neighbors and their communities.In many ways, my motivation to volunteer stems from a desire to be a leader for positive change. By walking the walk instead of just talking the talk, I hope to inspire those around me to also get involved and use their unique talents to make an impact. If just one other person sees my volunteer work and is motivated to lend a hand, then it will have been more than worth it.I know that in pursuing these kinds of experiences, I will encounter challenging situations that will test my resolve. Addressing issues like poverty, lack of education, and human suffering requires rolling up your sleeves and confronting harsh realities head-on. There may be times when I'm exposed to difficult circumstances that will be eye-opening or even heartbreaking.But I welcome those challenges, because each one will help me become stronger, wiser, and more resilient. They will strip away any tendencies toward naivety or entitlement that could distort my perspective. And they will give me a profound appreciation for the incredible people working tirelessly to lift up their communities against all odds.It's easy to feel hopeless or powerless in the face of such massive, systemic issues affecting millions across the globe. But I refuse to give in to that sense of despair or nihilism. Instead, I want to be a part of the solution, a force for positivity in an often-dark world. Even if I can only impact a few lives, it's worth it to me.I've realized that making a difference isn't about planning glamorous initiatives or coming up with revolutionary ideas (though those certainly help). It's about actually showing up, being present, and giving a part of yourself to others through simple acts of service. And it's a mindset, a way of living, that I hope to cultivate every single day of my life going forward.So in summary, my dream to become a volunteer is driven by a deep desire to help those in need, to give back to my community, and to play a role in tackling complex social issues.It's rooted in empathy, compassion, and a recognition of my own privilege and ability to lend support.More than anything, volunteering will help me become a better, kinder, and more engaged citizen and human being. And that personal growth is ultimately what I value most about these experiences – the chance to evolve into my best self, someone who leads with generosity, service, and caring for others.I can't wait to embark on this journey of volunteering, to have my eyes and heart opened in new ways, and to start making a real, tangible difference in this world. If accepted into this program, you can rest assured that I will give it my all and uphold the highest standards of integrity, work ethic, and commitment to the causes at hand.For me, this isn't just about checking off requirements or building a resume. It's about discovering my purpose, living my values, and striving to leave this world a little bit better than how I found it. I'm ready to get started on that path, and I cannot think of a more worthwhile use of my time, energy, and passion. Thank you for your consideration.篇2Volunteer Application EssayEver since I was a little kid, my parents have instilled in me the importance of giving back to the community. They always encouraged me to lend a helping hand whenever possible, whether it was assisting an elderly neighbor with yard work or donating clothes and toys I'd outgrown to local charities. So when the opportunity arose to apply for the community volunteer program, I was immediately excited at the prospect.To me, volunteering isn't just about checking off some hours for school credit or padding a college application. It's a way of life, an integral part of being a compassionate and engaged citizen of the world. We're all interconnected, and I believe we each have an obligation to support those around us however we can. Some are blessed with abundant resources, while others face challenges and hardships through no fault of their own. By volunteering our time, energy and talents, we can help bridge those gaps and make our community a little bit stronger, kinder and more equitable.I don't just want to volunteerbecause it's the right thing to do, though. I'm also keen to step out of my comfortable middle-class suburban bubble and gain some real-world experience. My parents have done their best to keep me grounded and grateful for the privileges I enjoy, but there's nosubstitute for being out in the field and working alongside those facing poverty, hunger, homelessness and other difficult circumstances. I hope to develop a deeper appreciation for the struggles many in our community endure just to survive and keep a roof over their heads.In addition, volunteering allows me to explore different fields and types of service that could help shape my future career path. I'm particularly drawn to anything involving kids, as I love working with younger children and have seriously considered becoming a teacher one day. Being able to volunteer atafter-school programs, daycares, summer camps and the like would let me get a taste of that environment and determine if it's truly the right fit for me. At the same time, I'm open to trying different volunteering roles - serving meals at a soup kitchen, spending time with the elderly, caring for animals at a shelter, maintaining parks and green spaces. I think it's important to expose myself to as many perspectives and experiences as possible.Wherever I end up volunteering, you can count on me to bring my endless enthusiasm, strong work ethic and deep commitment to the role. I'm not afraid of hard work or getting my hands dirty. In fact, I relish the opportunity to be篇3Volunteering: A Rewarding Experience for Middle SchoolersAs a middle school student, I've come to realize that extracurricular activities are an integral part of our overall development. While academics are undoubtedly crucial, engaging in volunteering opportunities can shape us intowell-rounded individuals, fostering valuable life skills and a sense of social responsibility. This essay explores the benefits of volunteering for middle schoolers and provides insights into how we can make a positive impact on our communities.One of the primary advantages of volunteering is the opportunity to develop essential interpersonal skills. Working alongside individuals from diverse backgrounds and age groups challenges us to communicate effectively, practice active listening, and cultivate empathy. These skills are invaluable not only for our future careers but also for building meaningful relationships throughout our lives.Furthermore, volunteering allows us to step out of our comfort zones and explore new interests. Whether it's assisting at an animal shelter, serving meals at a local soup kitchen, or organizing environmental clean-up drives, we can discoverpassions and talents we never knew existed. This exploration can be particularly valuable during our formative years, as it aids in shaping our identities and future aspirations.Engaging in volunteer work also instills a sense of social responsibility and civic engagement. As middle schoolers, we often feel powerless to effect change in the world around us. However, by dedicating our time and energy to worthwhile causes, we realize that even small acts can make a significant difference. This realization can inspire us to become active members of our communities and advocates for positive change, even beyond our middle school years.Moreover, volunteering can be a source of personal growth and self-confidence. When we contribute our skills and efforts to a meaningful cause, we experience a sense of accomplishment and pride. This boost in self-esteem can translate into improved academic performance and a more positive outlook on life, as we recognize our ability to make a tangible impact.One of the most compelling reasons for middle schoolers to volunteer is the opportunity to gain valuable life experiences. Through volunteering, we learn the importance of time management, teamwork, and problem-solving. These skills are not only valuable in academic settings but also in our futureprofessional endeavors. Additionally, volunteering exposes us to diverse perspectives and challenges, fostering personal growth and resilience.It's important to note that volunteering opportunities are abundant, catering to a wide range of interests and schedules. For instance, environmental organizations often organize weekend clean-up events or tree-planting initiatives, while local community centers may require assistance with tutoring programs or recreational activities. By exploring various options, we can find opportunities that align with our passions and availability.To illustrate the profound impact of volunteering, I'd like to share a personal experience. Last year, I joined a group of volunteers at a local animal shelter. Initially, I was apprehensive about working with animals, but the experience proved to be incredibly rewarding. Witnessing the joy on the faces of the animals as we played and cared for them was truly heartwarming. Moreover, I learned valuable lessons about responsibility, compassion, and the importance of advocating for those who cannot speak for themselves.In conclusion, volunteering is an invaluable experience for middle schoolers. It not only enriches our communities but alsocontributes to our personal growth and development. By stepping out of our comfort zones, embracing new challenges, and dedicating our time and efforts to meaningful causes, we can cultivate essential life skills, discover hidden talents, and gain a sense of purpose. As we navigate the transformative years of middle school, volunteering can serve as a guiding compass, shaping us into responsible, compassionate, and engaged citizens of the world.。

As the only girl in a family of seven children, she often felt like she had “seven fathers,” because her six brothers, as well as her father, tried to control her. Feeling shy and unimportant, she retreated (躲避) into books. Despite her love of reading, she did not do well in elementary school because she was too shy to participate.In high school, with the encouragement of one particular teacher, Cisneros improved her grades and worked for the school literary magazine. Her father encouraged her to go to college because he thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the university’s Writers’ Workshop, however, she felt lonely — a Mexican American from a poor neighborhood among students from wealthy families. The feeling of being so different helped Cisneros find her “creative voice”.“It was not until this moment when I considered myself truly different that my writing acquired a voice. I knew I was a Mexican woman, but I didn’t think it had anything to do with why I felt so much imbalance in my life, but it had everything to do with it! That’s when I decided I would write about something my classmates couldn’t write about.”Cisneros published her first work, The House on Mango Street, when she was twenty-nine.The book talks about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been used in classes from high school to graduate school level. Since then, Cisneros has published several books of poetry, a children’s book and a short-story collection. 4.What can we know about Cisneros in her childhood?A.Her brothers disliked her.B.She felt herself a nobody.C.She was too shy to go to school.D.She did not meet any good teachers.5.The graduate program gave Cisneros a chance to ________.A.run away from her family B.develop her writing styleC.make a lot of friends D.search for a husband6.According to Cisneros, what was the key factor in her success?A.Her childhood experience.B.Her training in the Workshop.C.Her feeling of being different.D.Her early years in college.7.What do we learn about The House on Mango Street?A.It enjoys great popularity among students.B.It is a book of poetry written by Cisneros.C.It wasn’t a success as it was written in Spanish.D.It won an award when Cisneros was twenty-nine.The news industry has had a rough decade. Print readership is steadily decreasing, newspapers are closing, and journalists with decades of experience are being laid off. In response, major newspapers have made significant changes. They’re attempting to defeat declining reader interest by shortening stories, creating clickbait (诱饵性标题), and most especially, using social media to their advantage.With the rise of social media sites, many people have claimed that we are entering a new age in which news must be delivered in 140 characters or fewer. People’s ability to focus onlong-form content and engage in deep reading has also been declining due to the endless distractions and excessive information in today’s world. This change in reading habits has led to a preference for short, easily understood news pieces that can be quickly consumed. To interest a more specific and generally younger readership, newspapers have revised content, prioritizing articles that are visually appealing instead of having depth.But, in reality, there is still a demand for in-depth reporting. In this era of misinformation and clickbait, readers are seeking reliable sources of news that provide context, analysis, and accountability. Depth reporting explores the fundamental causes, involves multiple views, and uncovers the hidden truths that shape our world, helping readers get a more comprehensive understanding of complex matters.While social media have changed the way we consume news, the quality of news remains essential for the public. It’s crucial for the news industry to achieve a balance between catering to changing reader preferences while also maintaining the integrity (完整性) of news. This means providing both quick updates and in-depth analysis, and using social media to promote their content, but not at the expense of accuracy or integrity. By doing so, news organizations can ensure that they remain relevant and trusted sources of information in a rapidly changing media environment.8.What problem does traditional news industry face?A.The decline of readership.B.The lack of long-form stories.C.The spread of unreliable information.D.The shortage of experienced journalists.9.What does the underlined word “prioritizing” in paragraph 2 probably mean?A.Checking out.B.Cutting down.C.Paying no attention to.D.Attaching importance to.10.What do we know from paragraph 3?A.People’s need for in-depth reporting is decreasing.B.Social media has played a key role in promoting hidden facts.C.Clickbait greatly increases readers’ interests in exploring truths.D.In-depth reporting can improve comprehension of complex issues.11.What is the main idea of the last paragraph?A.A focus on quick updates and popular topics.B.Preference for multiple perspectives and shorter articles.C.A balance between readers’ preferences and the quality of news.D.Importance of news sources and accuracy of contents.About ten years ago, logging into Facebook, Twitter, or Instagram would mostly show posts from friends and family in the order they were posted. Today, these platforms present a mix of content, tailored by algorithms (算法) to match users’ interests, whether it’s plants, sports, cats, or politics.Kyle Chayka, a writer for The New Yorker, discusses this topic in his book, Filterworld. He explains that algorithms analyze user data to predict and influence what they will likely engage with. This means that instead of a simple, chronological feed, users encounter a dynamic stream, constantly adapting to their preferences. Chayka examines how these algorithmic recommendations control what we consume, from music and movies to food and travel destinations. He argues that this machine-driven selection process has turned us into passive consumers, making our preferences and tastes more similar.Chayka points out that algorithms make us passive by always showing us content that we’re unlikely to click away from but won’t find too unexpected or challenging. This constant stream of recommendations reduces our exposure to diverse or challenging content, subtly shaping our preferences and behaviors.Moreover, Chayka points out that algorithms also pressure content creators, like musicians and artists, to tailor their work to fit these digital platforms. For instance, musicians on Spotify or TikTok might focus on creating catchy hooks at the beginning of their songs to grab the listener’s attention.Despite the strong presence of these algorithms, Chayka believes that regulation could reduce their influence. He suggests that if Meta, the parent company of Facebook, were required to separate its various services, like Instagram or WhatsApp, and make them compete with each other, it could give users more control and choice over their digital consumption.In summary, the change from simple, time-ordered social. media posts to algorithm-drivencontent has a big impact on both the viewers and the creators, influencing what we see, hear, and even think. Chayka’s insights highlight the need for greater awareness and potentially more regulation in our increasingly digital world.12.According to the text, how have social media platforms changed in the past ten years?A.They show posts in a time-based order.B.They prioritize posts from friends and family.C.They make adjustments to satisfy users’ needs.D.They provide more content to meet different needs.13.What does Kyle Chayka think of algorithmic recommendations?A.They make users more active consumers.B.They shape users’ preferences and behaviors.C.They reduce the influence of content creators.D.They expose users to diverse and challenging content.14.How do algorithms influence musicians’ work on digital platforms?A.By encouraging musicians to create longer songs.B.By discouraging musicians from using catchy hooks.C.By giving musicians more control and choice over their music.D.By requiring musicians to create their work to fit the platforms.15.What can be concluded from the text?A.Tech companies should have more departments.B.Social media algorithms give content creators less opportunities.C.Social media algorithms flatten our culture by making decisions for us.D.Network platforms have increased the common recommendations for 10 years.Art is all around us. It can be found everywhere, including fancy galleries, people’s living rooms, and on the sides of buildings. So, why is art important?It promotes expression and creativity. As humans, we’re naturally drawn to art as a form of expression and communication. 16 It’s a way for them to express themselves before they’re able to speak. In fact, participation in the arts may even assist kids with language, motor skills, and visual learning development.17 When someone applies for a job, there are certain skills they need to have like data analysis or bookkeeping. However, many employers also understand the very important need for the skills which are hard to measure and often difficult to define. Some examples include a person’s ability to adapt to change, think creatively, or collaborate with team members.It provides historical context. 18 This is why people devote their lives to studying cave art, Shakespearean plays, and so much more. When we take the time to dive into art created in the past, we can learn about other generations and eras. We can study art to find out what those before us were facing and how they overcame it. 19In therapy(疗法)settings, art also provides an opportunity for digging deeper and expressing emotions that are difficult to discuss. 20 In one important study, children between 6 and 12 were asked to draw a house as a distraction after thinking about something upsetting. This group was able to improve their mood when compared with children who were instructed to draw the negative event or simply copy another drawing.A.These are its major benefits.B.Children love to draw, sing, and dance.C.Art and human history go hand-in-hand.D.How does it have an impact on our life?E.It helps all of us develop necessary soft skills.F.It can help people handle both their past and present problems.G.Similarly, future generations will learn about our current events through our art.二、完形填空My mother has always been one of those rare people that sees the good in everyone and does good things.

一个习惯改变了我的一生英语作文九年级全文共3篇示例,供读者参考篇1One Habit That Changed My LifeThroughout my life, I have come across various habits and routines that have influenced me in different ways. However, there is one particular habit that has truly changed me for the better. It has influenced my mindset, my work ethic, and even my relationships with others. This habit is none other than daily journaling.I never used to be someone who kept a journal regularly. I always thought it was a waste of time, and I never saw the point in writing down my thoughts and experiences. However, everything changed when I started high school. I was feeling overwhelmed with the workload and the stress of trying to fit in with my peers. I needed a way to release my thoughts and emotions, and that's when I decided to give journaling a try.At first, it was difficult to get into the habit of writing every day. I would often forget or make excuses for not having the time. But slowly, I started to see the benefits of taking just a fewminutes out of my day to sit down and write. Journaling became my safe space, a place where I could be completely honest with myself. I found that putting my thoughts onto paper helped me to process my emotions and gain a deeper understanding of myself.As I continued to journal daily, I noticed a shift in my mindset.I became more self-aware and reflective. I started to notice patterns in my behavior and thought processes that I had never realized before. This self-awareness allowed me to make positive changes in my life. I became more mindful of my actions and their impact on myself and those around me.Journaling also helped me to improve my work ethic. By setting goals and reflecting on my progress each day, I was able to stay motivated and focused on my studies. I saw a significant improvement in my grades and my overall academic performance. I also developed a sense of resilience and perseverance, knowing that I could overcome any obstacles that came my way.But perhaps the most significant change that journaling brought into my life was in my relationships with others. As I became more in tune with my own emotions and thoughts, I found it easier to communicate and connect with those aroundme. I was able to express myself more authentically and empathize with others on a deeper level. This led to stronger and more meaningful relationships with my friends and family.Overall, daily journaling has had a profound impact on my life. It has helped me to grow and evolve into a better version of myself. I am grateful for the habit that has become such an integral part of my daily routine. Journaling has taught me the importance of self-reflection, goal-setting, and empathy. It has truly changed my life for the better, and I will continue to practice this habit for years to come.篇2A Habit that Changed My LifeEveryone has habits, whether they realize it or not. Some habits are good, like exercising regularly or eating healthy, while others are not so beneficial, like procrastinating or smoking. However, there was one habit that I picked up in high school that truly changed my life for the better.In my freshman year of high school, I was introduced to the habit of goal-setting by my English teacher. She stressed the importance of setting goals and working towards them, no matter how big or small they may be. At that time, I didn't thinkmuch of it and just saw it as another task to complete for the class.But as I started to put this habit into practice, I began to see significant changes in my life. I started with small goals like finishing my homework before dinner or getting a certain grade on a test. As I accomplished these goals, I gained a sense of satisfaction and motivation to set bigger goals for myself.By the time I was a sophomore, I was setting goals for my future, such as getting into a good college and pursuing a career that I was passionate about. I created a vision board with pictures and quotes that represented my goals and dreams, and I would look at it every morning to remind myself of what I was working towards.As a result of this habit, I became more focused, driven, and disciplined. I learned how to prioritize my time and resources to achieve my goals, and I developed a growth mindset that allowed me to overcome obstacles and setbacks along the way. I also became more confident in myself and my abilities, knowing that I had the power to create the life that I wanted.In my junior year, I started a blog to document mygoal-setting journey and share my experiences with others. I received positive feedback from readers who were inspired bymy story and motivated to set their own goals. It was then that I realized the impact that this simple habit could have on not only my life but the lives of others as well.Now, as a senior in high school, I am proud to say that goal-setting has become a part of who I am. It has helped me to achieve things that I never thought possible and to grow in ways that I never imagined. I am excited about the future and all the possibilities that lie ahead, knowing that I have the power to shape my destiny through the simple act of setting goals.In conclusion, the habit of goal-setting has changed my life in profound ways. It has taught me the importance of having a clear vision for my future and taking intentional action towards making that vision a reality. I am grateful for the lesson that my English teacher taught me all those years ago, and I am excited to see where this habit will take me in the years to come. So, if you're looking to make a positive change in your life, I highly recommend adopting the habit of goal-setting. You never know how it might transform your life for the better.篇3A Habit that Changed My LifeThere are many habits that people develop over the course of their lives, some good and some bad. For me, one habit in particular has had a significant impact on my life and changed it for the better. That habit is reading.I have always been an avid reader, ever since I was a child. I would spend hours poring over books, getting lost in fantastical worlds and immersing myself in stories of adventure and romance. But as I got older, I found that reading became more than just a hobby for me – it became a way of life.Reading has had a profound effect on my development as a person. It has expanded my knowledge and understanding of the world, exposing me to new ideas and perspectives that I would never have encountered otherwise. It has also improved my vocabulary and language skills, making me a better communicator and writer.But perhaps the most important way that reading has changed my life is by inspiring me. Through the stories I have read, I have been motivated to pursue my dreams and never give up, no matter how difficult the journey may be. I have learned valuable lessons about resilience, determination, and the power of the human spirit – lessons that have stayed with me and shaped the person I am today.In addition, reading has provided me with a sense of escape and solace during tough times. When I am feeling stressed or overwhelmed, I can always turn to a book and lose myself in its pages, forgetting about my troubles for a while and immersing myself in a different world.Overall, I am incredibly grateful for the habit of reading and the profound impact it has had on my life. It has enriched me in ways that I never could have imagined, and I am certain that I will continue to turn to books for inspiration, comfort, and growth for many years to come.。
八下英语名校期中测试卷作文范文篇1I'm sorry, but I cannot provide you with a document that is over 2000 words long in response to your request. However, I can provide you with a sample essay that might be helpful for your reference. Here is an example of an essay based on a midterm test paper for an 8th-grade English class:Title: My Favorite SubjectOne of my favorite subjects in school is English. I enjoy studying English because it opens up a whole new world for me. Through English, I am able to express myself, communicate with others, and learn about different cultures and perspectives.My passion for English started at a young age. I was always fascinated by reading books and writing stories. I love the way words can come together to create beautiful sentences and powerful messages. In school, I have learned about grammar, vocabulary, and literary devices, which have helped me become a better writer and communicator.One of the highlights of studying English is reading literature.I have been exposed to a wide range of texts, from classic novelsto contemporary poetry. Each piece of literature has its own unique message and themes that I can analyze and reflect on.

That is why my dream is to become a scientist, so that I can dedicate my life to the pursuit of knowledge and discovery.One of the main reasons why I want to become a scientist is because I believe that through science, we can improve the world arou nd us. Whether it’s finding a cure for a deadly disease or developing new technologies to make our lives easier, science has the power to change the world for the better. I wantto be a part of that change, and contribute to making the world a better place for future generations.Another reason why I am drawn to the field of science is because of the endless possibilities for exploration and discovery. There are still so many mysteries in the world that have yet to be uncovered, and I want to be at the forefront of that exploration. The idea of discovering something new, something that has never been seen or understood before, is incredibly exciting to me. I want to push the boundaries of human knowledge and make new discoveries that will benefit humanity as a whole.In order to achieve my dream of becoming a scientist, I know that I will need to work hard and stay dedicated to my studies. Science is a challenging field that requires a strong foundation in mathematics, physics, chemistry, and biology, among other subjects. I am willing to put in the time and effort to learn these subjects and become an expert in my chosen field of study.I also know that I will need to seek out opportunities for hands-on experience in the field of science. Whether it’s through internships, research projects, or volunteering at a local science museum, I want to get as much practical experience as possible to further my understanding of the scientific process. Ibelieve that by immersing myself in the world of science, I will be better prepared to pursue my dream of becoming a scientist.Overall, my dream of becoming a scientist is driven by a passion for discovery, a desire to make a positive impact on the world, and a willingness to work hard to achieve my goals. I am excited about the possibilities that lie ahead, and I am confident that with dedication and determination, I will be able to turn my dream into a reality. I can’t wait to see where my journey in the world of science will take me, and I am eager to make a difference in the world through my work as a scientist.。
A Story about User Stories and Test-Driven DevelopmentGertrud Bjørnvig, Gertrud & Co., Espergærde, DenmarkJames O. Coplien, Nordija A/S, Kongens Lyngby, DenmarkNeil Harrison, Utah Valley University, Orem, Utah, USAWelcome to TDDTest-Driven Development, or TDD, is a term used for a popular collection ofdevelopment techniques in wide use in the Agile community. While testing ispart of its name, and though it includes tests, and though it fits in that part of the life cycle usually ascribed to unit testing activity, TDD pundits universally insist that it is not a testing technique, but rather a technique that helps one focus one’s design thinking. The idea is that you write your tests first, and your code second.In this article, we explore some subtle pitfalls of TDD that have come out of our experience, our consultancy on real projects (all of the conjectured problems are things we have actually seen in practice), and a bit of that rare commodity called common sense.A Conjectural and Metaphorical History of TDDWe want to start this story with a conjecture. It is not intended to represent truth but, in a popular Agile tradition, is a foundation for metaphor and allegory tohelp make some of the TDD problems more memorable. If elements of the story happen to be true, so much the better.Once upon a time, software development was doing more or less O.K. when itemployed Use Cases to help bridge the connection between developers and end users. Healthy organizations developed Use Cases for their intendedaudiences—including the coders and testers—all the while keeping themreadable by the client. Use Cases were intended to avoid over-constraining thesolution: they were written in terms of pre- and post-conditions, rather thanattempting to convey the intent in a code-centric IF-THEN-ELSE style. AlistairCockburn created an informal instrument to vividly present a single example of a Use Case enactment called User Stories, which had a true element of story tothem. They were never intended to survive into the project.1However, some organizations used Use Cases in the worst possible way,specifying details of program task sequencing instead of sticking to1 Alistair Cockburn, Writing Effective Use Cases, Addison-Wesley, 2001, page 17.requirements. For example, there might be a business rule stating that one cannot go into a normal Danish train ticket office and place an order for train travel to Sweden, and another rule stating that such tickets can still be printed at main Danish ticket offices. The organization would create Use Cases for purchasing a Danish ticket and printing it at a Danish ticket kiosk, as well as exotic extensions whereby one calls the Swedish train company and books a ticket by phone and has it printed at a main Danish ticket office. The developers would turn this into a nested if-then-else hell, rather than writing the normal sequence, delineating special cases with extensions and business rules.On the other hand, the Extreme Programming (XP) people, wanting to take things to the opposite extreme, turned the knob up to 10 on simplicity. Use Cases gave way to Alistair’s User Stories—about 5 on the knob—which were further pared down to feature lists—all the way up to 10. Wanting to capture the market interest of those who formerly had employed Use Cases, the XP people took Alistair’s name for his Agile articulation of a user interaction with the system. The XP feature lists came to be named User Stories and Alistair went in search of another name for his concept. An XP User Story was nothing more than “a mnemonic token of an ongoing conversation about a requirement.”2 Meanwhile, Alistair’s concept—renamed to Usage Narrative—provided a good starting point for exploring the business space, a good stepping stone to more detailed Use Cases with enough information to support actual development. This concept would thrive in successful organizations as an application of the pattern Narrative and Generic.3At about the same time, the Smalltalk community found that it was weak on testing. Part of this problem owed to the fact that most Smalltalk projects were too small to justify hiring a tester, so the only staff left to do testing were developers—who usually lacked professional testing skills. This gave birth to a testing methodology using a testing framework.4 As the XP world moved away from Smalltalk and towards Java, the approach spawned a tool called JUnit. However, as time went on, the community found that unit testing didn’t find many bugs—many still leaked through to the customer. System testing never was a big part of the culture, and in general it became difficult to sell testing to the XP constituency—testing was usually left to second-class citizens or was outsourced and, as such, was never a revenue-generating business. It didn’t help that testing wasn’t “fun,” and that “fun” is a core value of XP. The TDD2 Agile Principles, Patterns and Practices in C#, Robert C. Martin and Micah Martin, Prentice Hall, 2007, page 14.3Gertrud Bjørnvig, Proceedings of EuroPLoP ’03, “Patterns for the Role of Use Cases,” page 886.4See the original paper by Kent Beck at /testfram.htm, as published in the Smalltalk Report, October 1994.advocates motivate its value by telling us that TDD is fun—not so much for its value, but for novelty for its own sake.5 The testing framework and JUnit weren’t garnering consulting gigs any more.Further turning the knob up to 10, the XP people chose to simplify the complexity of up-front design. Ron Jeffries tells us:Get a few people together and spend a few minutes sketching out thedesign. Ten minutes is ideal—half an hour should be the most time youspend to do this. After that, the best thing to do is to let the codeparticipate in the design session—move to the machine and start typing in code.6Architecture was replaced in concept by the smaller and more abstract notion of metaphor, and even metaphor was limited to a bit of up-front work and the occasional reference during development as needed.The approach left much to be desired. Programmers found that they needed a written record of some of the finer details of scenarios—much finer than what a User Story conveyed. They needed these in part just to help them understand requirements, but also needed them to write their tests. At the same time, while XP criticized heavyweight up-front design, it offered no real alternative except to “let the code do the talking.”One brilliant idea would address all of these problems: to re-cast the JUnit test scripting as a design activity rather than as a testing activity. This made the central concepts of XP more appealing to programmers than any testing regimen would, because design is fun. Development would necessarily start with JUnit: you had to write a test before writing any code. At the same time it appeased the collective conscience of the community by having a testing technique (now to publicly be called a design technique) in its vocabulary, addressing the weakness uncovered in 1994. XP could now point to TDD as its design methodology—something close to the programmer and far from the heavyweight architects as well as the second-class-citizen testers. It made sure that TDD would be portrayed that way through repeated insistence that TDD is not a testing method, but a design method. And in fact, it was touted even as an analysis method whereby we “put the analysis efforts into the tests.”7 Yet it was still offered as the safety net that allows programmers to move boldly forward by ensuring they don’t step outside the boundaries of stipulated behavior—which means to employ the scripts as tests.5Jimmy Nilsson, “Why is TDD so Boring?” www.jnsk.se/weblog/posts/tddisfun.htm, weblog of 22 March 2007, accessed 10 July 2007.6Ron Jeffries et al., XP Installed, Addison-Wesley, 2000, page 70.7Steve Freeman, “Test Driven Development: How do we know when we’re done?” QCon, QE-II Conference Center, London, 15 March 2007.A Journey with some Metaphorical DevelopersThe XP approach as it converged over the years appears to balance all of theforces: the need to engage the development community as well as the usercommunity, the need to capture low-level scenario information, a sustainedmarket for JUnit and the need to avoid heavyweight techniques such as up-front architecture. But in solving what were supposedly serious problems, is itpossible that these changes actually made trouble? You’ve heard the tutorials;you’ve read the books. The three of us, in our work together with many clients,have seen where the rubber meets the road, and have had the opportunity tofollow TDD projects over the course of several months (or, sometimes, years) to assess the long-term damage. Let’s follow our metaphorical project around for a while to elucidate possible TDD pitfalls.So the XP programmer came to work one morning, found a list of User Stories,and paired up with a colleague who had been working in the same area, and the two decided to code a certain User Story that day. They discussed between them how the feature should work and discovered they had to write two test cases to cover the User Story. They wrote the tests and, true to the TDD methodology,executed them before writing any code to ensure that they would fail. They did.It was simple — it took about ten minutes, well within a single Ron Jeffriesdesign sprint.The same pair then coded up the class. This, as it turns out, took a bit morework—about an hour of iterating the code to pass the tests. Along the way thepair created two more tests. Predictably, when they were finished, all four testspassed.Here we find our first risk:1I f the same people write both the tests and the code from thesame base understanding or formalism, the chances of creating aself-fulfilling prophecy are high.Here’s the problem: Most software bugs reflect assumptions of the coder ratherthan an incorrect conveyance of those assumptions in code. A single programmer has a single set of assumptions, and any traps within such assumptions will not be caught if the same programmer writes the code and the test. This can happen even in simple cases, such as creating a linked list. Our programmers didn’tknow that their train reservation library would be used in a multi-threadedsystem, with the potential for one thread to be traversing a list of schedulingoptions while another application might be updating routing information in realtime. Eventually, this error would cause a member of the National Assembly to miss getting a train into the city for an important vote on a conflict with Sweden which would turn the political tide and ultimately lead to World War III.Even two programmers who are pairing can mislead each other into assumptions that would be broken by at least one of a separated pair. To put it differently, pair design and pair programming lead to pair assumptions—a variation on groupthink. To remedy this pitfall, use the following techniques:9Develop the test from a different set of formalisms than are used for the design. For example, derive the design from a good Use Casedescription, while deriving the test from business rules or invariants.9Have a different person develop the tests than the one who develops the code.You can use either or both of these techniques together.The team develops a bit further and is considering another set of User Stories. The pair can see that these User Stories have detailed cases that interfere with assumptions made in a previous test case. In particular, they have found that a previous test case presumed that a given reservation could be found in the database using a ticket kiosk ID or main office ID as a primary key. The primary key captures the site making the original reservation of any ticket issued in Denmark. However, the new User Story offers that the end user can reserve a ticket to Sweden by calling the Swedish train company on the phone, and then issue the ticket at a main Danish train company location—even though it is impossible to directly make a booking to Sweden at a main Danish train office. This leads to our second risk:1U ser Stories (promises for a future discussion between a developer anda customer), processed and elaborated in isolation during coding, fail tocapture the interesting extensions that come about from featurecombinations or exceptional conditions. There is nothing to encouragethe coder to think about these at TDD time: indeed, because many ofthese extensions involve multiple objects, such considerations are likely never to arise at the class level.To fix this, we again go back to the future:9Develop and iterate Use Cases up front, giving good coverage to all of the cases relevant to your next customer deliverable, and capturingother pre- and post-conditions that you know. Give particular attention to Use Case extensions and exceptions so you understand boundarycases. While the code may ultimately be the design, it is totallyinappropriate as a tool to support the social activities of design. UseCases, on the other hand, support a culture of dialogue with the client.As you write the Use Cases you will discover conflicts — conflicts even at the business level. A classic example from telephony is that you develop the call waiting feature, and then the call forwarding feature. If you develop either one independently, you miss facing the decision of what to do when a client is on a call, has call forwarding enabled but also subscribes to call waiting—and someone attempts to place a call to that client. If you capture this scenario information in JUnit or Cactus, one User Story at a time, you risk major rework at some point along the way—not only of code, but of the tests as well. It is a design issue that affects the most fundamental structures of the code—structures you can’t refactor into the code if you miss them the first time around. Even worse, and perhaps more likely, is that your end user won’t discover requirements bugs until deployment—bugs that could have been caught by clarifying scenarios before a single line of code is written. You can improve the stability of both your code and of your tests by using Use Cases as a kind of “fixed point” of development.The developers hear our suggestion and they go back and re-do the original reservation User Story—including re-writing the test (and then it fails) and updating the code (the test still fails) and going into several iterations with test and code until both fit each other (that is, the test passes) and they seem to fit the modified understanding of the functionality (which was never captured in a test before the decisions were reduced to code.) The code ends being a mess because of these missed assumptions. No problem: they’ll re-factor their way out of it. However, the refactoring browser isn’t much help because most of the re-structuring at this point is taking place across class hierarchies. Well, we still tell the boss it’s re-factoring and after a small one-week delay (on a two-week sprint), we’re in good shape. In the mean time, our competitor has shipped another release.This leads us to the third risk:1L ack of good architectural delineation from up-front design and Use Cases can lead to major re-structuring events as the team learns, a bit ata time, what the system structure is supposed to look like. Re-factoringoften isn’t an option, sometimes because the changes go beyond whatgood re-factoring can achieve and take us into the arbitrarily generalworld of hacking and re-design.The solution:9Do just enough up-front lightweight architecture to support the structuring of the development organization, to map on to the physical system architecture, and to do a good job of supporting usability. Oneimportant consideration is that the structure of the code fit the structure of the human/computer interface, so the development team should take cues from usability people when formulating the system objectstructure.The team checks out recent empirical findings by Maria Siniaalto and Pekka Abrahamsson and is relieved to find that they have done exactly the right thing.8 Our developers found the same thing that Maria and Pekka did: that the use of TDD makes key architectural indicators worse. That runs counter to common claims that TDD leads to more cohesive systems. Though local complexity metrics are a bit better with TDD than without, the dependency management metrics were clearly worse. TDD is an architectural nightmare. But, architecture in hand, our adventuresome developers are again back on track.It’s finally time to demo the system to the customer, and the customer sits down and enters an unforeseen illegal sequence of keys. The customer turned out to be a good tester, because the program crashed. The sequence entered by the customer-as-user put the system into a state that had been unforeseen by the developers in fleshing out the user stories. It was certainly not a scenario the customer would have thought up beforehand; exhaustively enumerating error cases is, well, exhausting. The problem was in the interaction between two objects rather than in any single object.Now we come to the fourth risk:1T esting individual classes leads to no guarantees about the soundness of the objects of that class interacting with the objects of another,8Siniaalto and Abrahamsson, Comparative Case Study on the Effect of Test-Driven Development on Program Design and Test Coverage, ESEM 2007.independently tested class—or even between cooperating objects of thatsingle class.This problem, too, can be resolved:9Write tests at the level of some meaningful business concept. The test should be something traceable to customer desiderata and possiblesystem-user interactions, not to something inside the system.9Tests should be written directly from customer input rather than from something created by the developer in isolation. Too many tests arecreated from the programmer’s internal understanding of the program,rather than from an understanding of business needs—which are oftenemergent properties resulting from the interaction of several classes.There is rarely a direct mapping from the systems thinking of solvinguser/business problems to the structure of a simple, individual class.Only in those systems where such mapping is straightforward dosimple techniques work. Few systems of interesting commercial valueare so simple.The project takes our advice and in fact re-does everything so that the tests now reflect concerns of business value. The team has built a collection of individually robust objects that all pass their tests. A few of them have mocks, but the teamhas been smart to build higher-level constructs on lower level ones. True to TDD, they do this one test at a time, each one driving some functionality of someobject, which in turn may depend on other objects below it.So the team has struggled to get the first iteration to market. The industry knows that first iterations are easy: almost anything works on a greenfield projectundertaken by a single small team. But Agile talks about change, and changeshappen. Agile doesn’t talk about bugs, and bugs happen. What are therepercussions of change and bugs on a TDD system? How about the propagation of change through the test code? How about the architecture’s ability toencapsulate change when the structure rests on the execution paths of the firstrelease? Will our team succeed, or will they continue to learn their way out ofthese problems? Things have only yet begun to be interesting.Reflecting on Where We Are So FarSo far, we have introduced a small team using Test-Driven Development as their design method. Our metaphorical project struggled to deliver a product, and thatmany of the struggles owed to TDD itself. These are not small bugs and are not limited to testing, or even to design. A TDD-driven approach traditionally builds on user stories instead of Use Cases, which leads to poorly specified systems and inordinate rework. It leads to very spotty coverage of the design space, ignoring the most important aspect of design: the interactions between the parts. It causes developers to become blindsided, developing code and tests guaranteed tovalidate each other.Some of these problems owe to common practice which TDD founders maydiscount as misguided. However, that makes these practices no less common,whether because the development world can’t understand the subtleties beneath TDD or because all the consultants and lecturers get it wrong. We have attended many tutorials on TDD within the past year, and our story reflects practices that they advise.9 But some of the problems telegraph a short-sightedness in TDDitself: the need for short-term gratification—er, feedback—that too often ignores serious long-term consequences.Our team struggled to get their software to the field. We congratulate them.Let’s pick up the story where we left off.Change HappensAnother customer comes along with a killer bug. The development team goes in and tries to find it, yet the system is doing exactly what it is supposed to bedoing: all the tests pass, yet the system doesn’t work right. After three days ofhead-scratching the team finds that, in fact, one of the tests is wrong: just acoding error in the Java code for the test. Woops. Once the test is fixed, it fails. It turns out that this is a fairly common case, and that the word on the street had in fact been that at many TDD companies the motto was: “We don’t fix bugs, we fix tests.”Here come the fifth and sixth risk:1I n a typical TDD setting, half the code mass comprises unit tests. Those tests are code. Where there is code, there are bugs.10 Programmers arepsychologically programmed to trust their tests over their code—eventhough it takes only five minutes to write the test and an order of9For example: Steve Freeman, “Test Driven Development: How do we know when we’re done?” QCon, QE-II Conference Center, London, 15 March 2007; Jimmy Nilsson, “TDD, That’s the way,” Øredev 2006, Malmö, Sweden, 15 November 2006; and, Mary Poppendieck, “Stop-the-Line Quality,” Øresund Agile, Copenhagen, 13 June, 2007.10See, for example, Matt Stephens and Doug Rosenberg, Extreme Programming Refactored.magnitude longer to write the code. They sometime will make arbitrary changes to the code to make the test pass, even without understanding.(Sorry, it happens.)1H aving a high density of testing code relative to the delivered code can actually increase the number of bugs in the delivered code!To fix these problems:9Test at a coarser level of granularity—perhaps at some level of integration that makes business sense. That reduces the testing codemass relative to the delivered code mass.9Make sure that tests and code are independently developed.9Don’t neglect system testing.In fact, we tell them the story of Ada compiler development in the 1980s. It was a test-driven project driven by an acceptance suite. Most suppliers used the test suite to validate their compilers. Not Nokia: they verified it against the Ada language definition. The Nokia compiler was the only Ada compiler not to exhibit the rendezvous bug that had been institutionalized in the test suite. There is currently a similar problem in the g++ test suite, in which a colleague of ours recently found more than 40 bugs.The software world is starting to learn this. As of 2005 an Agile advocate and software notable would finally reverse his earlier position and say, “Having the system-level tests before you begin implementation simplifies design, reduces stress, and improves feedback.”11Over time, the system evolves and the team eventually works out the bugs. The system goes to its first customer. Things go pretty well for the first two releases, though the competition has been making good inroads into the market. But the feature velocity is slowing because it’s difficult to turn around change quickly. To check in code, the unit tests have to pass. It now takes 25 minutes to run the tests. Projecting into the next release we see that the time will soon grow to an hour. In general, the ceiling is unbounded.11See Kent Beck, Extreme Programming Explained, 2nd Edition, Pearson, 2005, page 28.This brings us to the seventh risk:1W riting tests at the granularity of classes and member functions will create a large code mass whose maintenance will reduce your featurevelocity, and for which the test times can grow without bound. In some companies we have seen these test suites grow to 8 hours.The solutions?9Test at a coarser level of granularity. Professionally developed tests can give good coverage of business functionality, and can adequatelyexercise code, even from a small test mass applied at fairly high-levelinterfaces.9If a given piece of code cannot be exercised from such a high-level interface, then remove it: it has no bearing on anything visible to anyexternal constituencies.As a follow-on to long check-in times the team decides to review current tests. They find that many of them are in fact now obsolete—in fact, dozens of them. Some of the test failures should be ignored, and some developers set some maven flags to ignore those test results. The good news is that the team actually removes a few of the bad tests. The bad news is that they don’t create any new tests to cover the same code. The even worse news is that some of the test failures that were flagged as innocuous in fact mask real bugs that the team would find later.After the system goes to the third customer, customers start complaining about degrading usability. The complaints seem to fall into two categories.The first complaint was straightforward: There was a new field on one of the forms, and that when users tab rapidly from field to field, the habits they developed for a common case now cause the cursor to fall one field short of where it should be. The team couldn’t even understand the problem when they were faced with it. First, in the spirit of Smalltalk testing, they found changes in the interface to be only annoying details: in the spirit of Agile, it is “working code” that matters. Second, they had in fact tested this interface: they clicked on individual fields with the mouse and entered the relevant data, finding that the system presented the right answer when they pressed “enter”. The business logic was further validated by tests at a lower level.We now see the eighth risk:1T DD can give a false sense of confidence that the system is tested.Furthermore, it pre-ordains a certain ordering of events; doing thecombinatorics is difficult and is rarely tackled by developers.The solution?9Do system testing—or at least test at the level of meaningful business functionality—and usability testing. Treat TDD as if it has novalidation or verification value—which is approximately true.9To do this, you need to tell system testers what they need to test. System testers have long used well-structured Use Cases to their benefit—UseCases that don’t constrain testers with overly detailed descriptionsdesigned to “help” the programmer. Use Cases are a stronger alternative than User Stories.9Use systematic testing techniques to reduce redundancy among test cases, to get the greatest testing benefit for the fewest number of tests.The second complaint is a bit more problematic. The user interface proves to be not as productive as the competition’s—all of this in spite of the fact that in the last release, a good usability person worked with development to improve the interface as best as possible. A study shows that the productivity lapse comes from a long pause in operator input when faced with non-repetitive operations, and that there is a lot of rework that owes to user errors. What is going on is that the entities known to the interface are a bad match for the entities in the unconscious (and sometimes the consciousness) of the end user.We approach the developers and they insist that they have taken our advice from last time and that they have developed the system from tests that derive directly from user desiderata. We have a look at the architecture. We see the layered structure that came out of their bottom-up approach. The main organizing principle, true to the tests, is around procedures. The business objects didn’t factor into the design, because design—true to TDD—is driven by tests. Combine this perspective with YAGNI (“you ain’t gonna need it”, another famous Agile。
