You work in a loop: write code, get feedback, iterate. The faster you get feedback, the faster you can learn and become a more effective developer. Test-Driven React helps you refine your React workflow to give you the feedback you need as quickly as possible. Write strong tests and run them continuously as you work, split complex code up into manageable pieces, and stay focused on what's important by automating away mundane, trivial tasks. Adopt these techniques and you'll be able to avoid productivity traps and start building React components at a stunning pace!

You work in a loop: write code, get feedback, adjust. The faster you get feedback, the faster you can learn and become a more effective developer. Turn your React project requirements into tests and get the feedback you need faster than ever before. Stay focused on what's important by running your tests continuously in the background. The second edition of Test-Driven React has been extensively revised to reflect the latest tools and techniques for React development, including TypeScript. Combine the power of testing, linting, and typechecking directly in your coding environment to iterate on React components quickly and fearlessly! React revolutionized web development by abstracting away the details of DOM manipulation. That conceptual elegance has opened the door to a new generation of web testing: clear, expressive, and lightning fast. That makes React a perfect fit for test-driven development (TDD), a methodology in which tests are a blueprint instead of an afterthought. Each chapter presents new projects to challenge you and new tools to help you. Write fast, easy-to-understand tests with Vitest and React Testing Library. Keep your code tidy with ESLint and Prettier. Perform every task you need from a single window within VS Code. See your test output directly in your code with Wallaby. Style components in a test-friendly way with styled-components. By understanding every piece of your project's stack, you'll feel more confident and able to focus on what matters: writing reliable and maintainable code. The second edition of Test-Driven React has been updated to use TypeScript, the language of choice for modern React development. Find and fix type errors without even running your code. Generate beautiful documentation from type annotations with Storybook, and update it on every commit with GitHub Actions. Discover a more joyful React development experience. Let your tests lead the way! What You Need: You'll need a working knowledge of JavaScript or TypeScript, and a computer running macOS, Windows, or Linux.

Quite simply, test-driven development is meant to eliminate fear in application development. While some fear is healthy (often viewed as a conscience that tells programmers to "be careful!"), the author believes that byproducts of fear include tentative, grumpy, and uncommunicative programmers who are unable to absorb constructive criticism. When programming teams buy into TDD, they immediately see positive results. They eliminate the fear involved in their jobs, and are better equipped to tackle the difficult challenges that face them. TDD eliminates tentative traits, it teaches programmers to communicate, and it encourages team members to seek out criticism However, even the author admits that grumpiness must be worked out individually! In short, the premise behind TDD is that code should be continually tested and refactored. Kent Beck teaches programmers by example, so they can painlessly and dramatically increase the quality of their work.

By taking you through the development of a real web application from beginning to end, the second edition of this hands-on guide demonstrates the practical advantages of test-driven development (TDD) with Python. You’ll learn how to write and run tests before building each part of your app, and then develop the minimum amount of code required to pass those tests. The result? Clean code that works. In the process, you’ll learn the basics of Django, Selenium, Git, jQuery, and Mock, along with current web development techniques. If you’re ready to take your Python skills to the next level, this book—updated for Python 3.6—clearly demonstrates how TDD encourages simple designs and inspires confidence. Dive into the TDD workflow, including the unit test/code cycle and refactoring Use unit tests for classes and functions, and functional tests for user interactions within the browser Learn when and how to use mock objects, and the pros and cons of isolated vs. integrated tests Test and automate your deployments with a staging server Apply tests to the third-party plugins you integrate into your site Run tests automatically by using a Continuous Integration environment Use TDD to build a REST API with a front-end Ajax interface
