Overview of this book

Test-driven development (TDD) is a development approach that relies on a test-first procedure that emphasizes writing a test before writing the necessary code, and then refactoring the code to optimize it.The value of performing TDD with Java, one of the longest established programming languages, is to improve the productivity of programmers and the maintainability and performance of code, and develop a deeper understanding of the language and how to employ it effectively. Starting with the basics of TDD and understanding why its adoption is beneficial, this book will take you from the first steps of TDD with Java until you are confident enough to embrace the practice in your day-to-day routine.You'll be guided through setting up tools, frameworks, and the environment you need, and we will dive right into hands-on exercises with the goal of mastering one practice, tool, or framework at a time. You'll learn about the Red-Green-Refactor procedure, how to write unit tests, and how to use them as executable documentation.With this book, you'll also discover how to design simple and easily maintainable code, work with mocks, utilize behavior-driven development, refactor old legacy code, and release a half-finished feature to production with feature toggles.You will finish this book with a deep understanding of the test-driven development methodology and the confidence to apply it to application programming with Java.

Tools, Frameworks, and Environments

"We become what we behold. We shape our tools and then our tools shape us."
– Marshall McLuhan

As every soldier knows his weapons, a programmer must be familiar with the development ecosystem and those tools that make programming much easier. Whether you are already using any of these tools at work or home, it is worth taking a look at many of them and comparing their features, advantages, and disadvantages. Let's get an overview of what we can find nowadays about the following topics and construct a small project to get familiar with some of them.

We won't go into the details of those tools and frameworks, since that will be done later on in the following chapters. The goal is to get you up and running, and provide you with a short overview of what they do and how.

The following topics will be covered in this...
