 TestFixtureAttribute TestFixtureAttribute is used to mark a class that represents a TestFixture.

 TestFixtureData

 TestFixtureSetUpAttribute Attribute used to identify a method that is called before any tests in a fixture are run.

 TestFixtureSourceAttribute TestCaseSourceAttribute indicates the source to be used to provide test fixture instances for a test class.

 TestFixtureTearDownAttribute Attribute used to identify a method that is called after all the tests in a fixture have run. The method is guaranteed to be called, even if an exception is thrown.

 TestOfAttribute Indicates which class the test or test fixture is testing

 TestParameters TestParameters class holds any named parameters supplied to the test run

 TheoryAttribute Adding this attribute to a method within a class makes the method callable from the NUnit test runner. There is a property called Description which is optional which you can provide a more detailed test description. This class cannot be inherited.

 Throws Helper class with properties and methods that supply constraints that operate on exceptions.

 ValuesAttribute ValuesAttribute is used to provide literal arguments for an individual parameter of a test.

 ValueSourceAttribute ValueSourceAttribute indicates the source to be used to provide data for one parameter of a test method.

 Warn Provides static methods to express conditions that must be met for the test to succeed. If any test fails, a warning is issued.

 ActionTargets The different targets a test action attribute can be applied to

 ParallelScope The ParallelScope enumeration permits specifying the degree to which a test and its descendants may be run in parallel.

 SpecialValue The SpecialValue enum is used to represent TestCase arguments that cannot be used as arguments to an Attribute.

 DirectoryAssert Asserts on Directories

 Does Helper class with properties and methods that supply a number of constraints used in Asserts.

 FileAssert Asserts on Files

 GlobalSettings GlobalSettings is a place for setting default values used by the framework in performing asserts. Anything set through this class applies to the entire test run. It should not normally be used from within a test, since it is not thread-safe.

 CombiningStrategyAttribute Marks a test to use a particular CombiningStrategy to join any parameter data provided. Since this is the default, the attribute is optional.

 DataAttribute The abstract base class for all data-providing attributes defined by NUnit. Used to select all data sources for a method, class or parameter.

 IncludeExcludeAttribute Abstract base for Attributes that are used to include tests in the test run based on environmental settings.

 NUnitAttribute The abstract base class for all custom attributes defined by NUnit.

 ResultStateException Abstract base for Exceptions that terminate a test and provide a ResultState.

 TestActionAttribute Provide actions to execute before and after tests.

 ITestAction When implemented by an attribute, this interface implemented to provide actions to execute before and after tests.
