Pragmatic Unit Testing in C# with NUnit by Andy Hunt, Dave Thomas, David Thomas

Learn how to improve your C# coding skills using unit testing. Despite it's name, unit testing is really a coding technique, not a testing technique. Unit testing is done by programmers, for programmers. It's primarily for our benefit: we get improved confidence in our code, better ability to make deadlines, less time spent in the debugger, and less time beating on the code to make it work correctly.This book shows how to write tests, but more importantly, it goes where other books fear to tread and gives you concrete advice and examples of what to test—the common things that go wrong in all of our programs. Discover the tricky hiding places where bugs breed, and how to catch them using the freely available NUnit framework. It's easy to learn how to think of all the things in your code that are likely to break. We'll show you how with helpful mnemonics, summarized in a handy tip sheet (also available from our website).With this book you will:

  • Write better code, and take less time to write it
  • Discover the tricky places where bugs breed
  • Learn how to think of all the things that could go wrong
  • Test individual pieces of code without having to include the whole project
  • Test effectively with the whole team
We'll also cover how to use Mock Objects for testing, how to write high quality test code, and how to use unit testing to improve your design skills. We'll show you frequent "gotchas"—along with the fixes—to save you time when problems come up.But the best part is that you don't need a sweeping mandate to change your whole team or your whole company. You don't need to adopt Extreme Programming, or Test-Driven Development, or change your development process in order to reap the proven benefits of unit testing. You can start unit testing, the pragmatic way, right away.

This is a great introduction to writing unit tests in C# with NUnit. The authors do a good job of explaining why unit tests should be created, how having unit tests are better than not having unit tests, and what exactly should be coded for in a unit test. The book is well-written, easy to follow, and includes helpful guidelines for things that might be confusing to developers. The real strength of this book is not the author¿s approach to writing unit tests, but rather they clearly illustrate what exactly should be tested in a unit test. The authors show how adhering to the guidelines they set forth results in unit tests that are well-written and fail at appropriate times. The authors then generalize this to some extent and provide an excellent discussion on the properties of a good unit test. My favorite section of the book was actually one of the appendices. In the first appendix, the authors go through a list of gotchas¿both in writing unit tests in general and specific to unit tests in C#. This is a very short discussion (only 6 pages), but they identify some issues I¿ve seen with poorly written unit tests. This is a great book as an introduction to writing unit tests. The authors clearly explain why unit tests should be written, they show clearly what should be tested in a unit test, and they describe some of the problems that have been avoided by writing intelligent unit tests.
