### ExplicitAttribute (NUnit 2.2)

The Explicit attribute causes a test or test fixture to be ignored unless it is explicitly selected for running. The test or fixture will be run if it is selected in the gui, if its name is specified on the console runner command line as the fixture to run or if it is included by use of a Category filter.

An optional string argument may be used to give the reason for marking the test Explicit.

If a test or fixture with the Explicit attribute is encountered in the course of running tests, it is skipped unless it has been specifically selected by one of the above means. 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.
