Test-Driven Java Development, Second Edition - Second Edition

By: Viktor Farcic, Alex Garcia

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.

The book store BDD story


Before we start, clone the code that is available at https://bitbucket.org/vfarcic/tdd-java-ch08-books-store. It is an empty project that we'll use throughout this chapter. As with previous chapters, it contains branches for each section, in case you miss something.

We'll write one BDD story that will be in a pure text format, in plain English and without any code. That way, all stakeholders can participate and get involved independently of their coding proficiency. Later on, we'll see how to automate the story we're writing.

Let us start by creating a new file called administration.story inside the stories directory:

We already have the narrative that we wrote earlier, so we'll build on top of that:

Narrative: 
In order to manage the book store collection efficiently 
As a store administrator 
I want to be able to add, update, and remove books 

We'll be using JBehave format for writing stories. More details regarding JBehave are coming soon. Until then, visit http:/...
