CategoryAttribute (NUnit 2.2)

The Category attribute provides an alternative to suites for dealing with groups of tests. Either individual test cases or fixtures may be identified as belonging to a particular category. Both the gui and console test runners allow specifying a list of categories to be included in or excluded from the run. When categories are used, only the tests in the selected categories will be run. Those tests in categories that are not selected are not reported at all.

This feature is accessible by use of the /include and /exclude arguments to the console runner and through a separate "Categories" tab in the gui. The gui provides a visual indication of which categories are selected at any time.
