Attributes

NUnit uses custom attributes to identify tests. All NUnit attributes are contained in the NUnit.Framework namespace. Each source file that contains tests must include a using statement for that namespace and the project must reference the framework assembly, nunit.framework.dll.

This table lists all the attributes supported by NUnit.
