about this book

How to use this book

If you’ve never written unit tests before, this book is best read from start to finish so you get the full picture. If you already have experience, you should feel comfortable jumping into the chapters as you see fit.

Who should read this book

The book is for anyone who writes code and is interested in learning best practices for unit testing. All the examples are written in C# using Visual Studio 2008, so .NET developers will find the examples particularly useful. But the lessons I teach apply equally to most, if not all, statically typed object-oriented languages (VB.NET, Java, and C++, to name a few). If you’re a developer, team lead, QA engineer (who writes code), or novice programmer, this book should suit you well.

Roadmap

The book is divided into four parts.

Code conventions and downloads

You can download the source code for this book from the book’s site at www.ArtOfUnitTesting.com, as well as from the publisher’s website at www.manning.com/TheArtofUnitTesting.

All source code in listings or in the text is in a fixed-width font like this to separate it from ordinary text. In listings, bold code indicates code that has changed from the previous example, or that will change in the next example.

Code annotations accompany some of the listings, highlighting important concepts. In some cases, numbered bullets link to explanations that follow in the text.

Software requirements

To use the code in this book, you need at least Visual Studio C# Express (which is free), or a more advanced version of it (Professional or Team Suite, for example). You’ll also need NUnit (an open source and free framework) and other tools that will be referenced where they’re relevant. All the tools mentioned are either free, open source, or have trial versions you can use freely as you read this book.
