Writing Maintainable Unit Tests
Writing Maintainable Unit Tests
Mastering the art of loosely coupled unit tests
About the Book
Are unit tests causing you pain? Are they constantly failing whenever you make changes to your production code? Do you spend a lot of time fixing them when they break? Are they difficult to set up and run? Do you have a hard time maintaining or structuring your unit test code? Are they causing you headaches from time to time? Are you ready to give up on writing unit tests or have you already done so?
Or do you just want to step up your game and want to learn more about how to write readable and maintainable unit tests?
This book is for software developers who want to improve upon their existing skills for writing unit tests. You will learn how to build loosely coupled, highly maintainable and robust unit tests that are trustworthy and improve the overall code quality of your software applications. The content of this book is based on 15+ years of experience with Test-Driven Development.
Although the examples in this book are written in C#, the principles and guidance are broadly applicable to other platforms and programming environments as well. So you will be able to universally apply this knowledge throughout the rest of your career.
