Chapter 20. Unit Testing
Application testing is one of the most time-consuming parts of writing software. Research into development teams and how they operate has revealed quite staggering results. Some teams employ a tester for every developer they have. Others maintain that the testing process can be longer than the initial development. This indicates that, contrary to the way development tools are oriented, testing is a significant portion of the software development life cycle. This chapter looks at a specific type of automated testing that focuses on testing individual components, or units, of a system.
Visual Studio 2008 has a built-in framework for authoring, executing, and reporting on test cases. Previously included only in the Team System Edition of Visual Studio, many of the testing tools are now available in the Professional Edition. This means a much wider audience can now more easily obtain the benefits of more robust testing. This chapter focuses on unit tests and adding support to drive the tests from a set of data.
