PlatformAttribute (NUnit 2.2.2)

The Platform attribute is used to specify platforms for which a test or fixture should be run. Platforms are specified using case-insensitive string values and may be either included or excluded from the run by use of the Include or Exclude properties respectively. Platforms to be included may alternatively be specified as an argument to the PlatformAttribute constructor. In either case, multiple comma-separated values may be specified.

If a test or fixture with the Platform attribute does not satisfy the specified platform requirements it is skipped. The test does not affect the outcome of the run at all: it is not considered as ignored and is not even counted in the total number of tests. In the gui, the tree node for the test remains gray and the status bar color is not affected.

Note: In versions of NUnit prior to 2.4, these tests were shown as ignored.
