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 focus on .NET-specific issues for TDD, including the best time to employ the inherent features of .NET class libraries and how to use NUnit, a leading unit-testing framework for .NET. And 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 WindowsR Forms, Web services, and other useful applications.
With the clarity and precision intrinsic to the Test-Driven Development (TDD) process itself, experts James Newkirk and Alexei Vorontsov demonstrate how to implement TDD principles and practices to drive lean, efficient coding-and better design. The best way to understand TDD is to see it in action, and Newkirk and Vorontsov walk step by step through TDD and refactoring in an n-tier, .NET-connected solution. And, as members of the development team for NUnit, a leading unit-testing framework for Microsoft .NET, the authors can offer matchless insights on testing in this environment-ultimately making their expertise your own.
Test first-and drive ambiguity out of the development process:
- Document your code with tests, rather than paper
- Use test lists to generate explicit requirements and completion criteria
- Refactor-and improve the design of existing code
- Alternate programmer tests with customer tests
- Change how you build UI code-a thin layer on top of rigorously tested code
- Use tests to make small, incremental changes-and minimize the debugging process
- Deliver software thatâs verifiable, reliable, and robust

As opposed to conventional development, TDD solves a different set of problems. It does so by proposing that before you write any nontrivial piece of production code, you write tests that the code will at first fail, and then when written correctly, will pass. TDD advocates say this approach has two major benefits. First, because the tests embody specific uses of the yet-unwritten software, they will help tease out the design of the software, complementary to other techniques such as requirements specification and modeling. Second, the tests create a safety net, enabling the programmer to engage in the risky but necessary practice of refactoring--continuously reorganizing the code--without fear of breakage (from Infoworld, August 8, 2003) With the clarity and precision intrinsic to the Test-Driven Development (TDD) process itself, experts James Newkirk and Alexei Vorontsov demonstrate how to implement TDD principles and practices to drive lean, efficient coding -- and better design.

Apply the concepts and techniques of Test-Driven Development to building Microsoft .NET-connected applications. Two experts in agile software development demonstrate by example how to use tests to drive lean, efficient coding and better design In this chapter, we define test-driven development (TDD) and then describe a process for applying it when developing software.
