With the increased interest in agile software development, unit testing has taken a more prominent role in the development cycle. Using automated, repeatable unit tests is fast becoming commonplace for many development teams to verify and test their code. Development teams do this as an active part of development, rather than at the end of development. Using an automated testing framework, teams can create a set of repeatable tests for anyone on the team to run against the current build of the system. Through these tests, development teams can verify that new code additions or a change does not break existing code.

In this article, I will introduce automated unit testing in a .NET environment. Many of the concepts described within are not new to Java and Smalltalk developers, however, many Visual C++ and Visual Basic developers, as well as .NET developers, may not be familiar with them.
