Test Driven Development: By Example

Presents an approach to writing software that emphasizes automated testing before and during coding. Written for advanced programmers, the book walks through two example projects--multi-currency arithmetic and the xUnit testing framework--and provides patterns for deciding what tests to write and how to write tests using xUnit. The code is written in Java and Python.

(Note: This is one of the original books on Test Driven Development, and written by Kent Beck, one of the leading proponents. Although the code is in Java, we still strongly recommend it)

Test Driven Development in Microsoft .NET

Learn how to apply the concepts and techniques of Test-Driven Development (TDD) to writing software for Microsoft .NET. Two experts in agile software development teach—using a wealth of pragmatic examples in C# and other .NET development tools—how to use automated tests to drive lean, efficient coding and better design. You’ll see real-world examples of TDD-for .NET projects, including a Microsoft ADO.NET relational database, a user interface created with Microsoft ASP.NET and Microsoft Windows® Forms, Web services, and other useful applications.

Pragmatic Unit Testing with NUnit

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 (which will work in Zanebug). 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).
