Assert The Assert class contains a collection of static methods that implement the most common assertions used in NUnit.

 AssertionException Thrown when an assertion failed.

 AssertionHelper AssertionHelper is an optional base class for user tests, allowing the use of shorter names for constraints and asserts and avoiding conflict with the definition of , from which it inherits much of its behavior, in certain mock object frameworks.

 Assume Provides static methods to express the assumptions that must be met for a test to give a meaningful result. If an assumption is not met, the test should produce an inconclusive result.

 CategoryAttribute Attribute used to apply a category to a test

 CollectionAssert A set of Assert methods operationg on one or more collections

 CombinatorialAttribute Marks a test to use a combinatorial join of any argument data provided. NUnit will create a test case for every combination of the arguments provided. This can result in a large number of test cases and so should be used judiciously. This is the default join type, so the attribute need not be used except as documentation.

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

 CultureAttribute CultureAttribute is used to mark a test fixture or an individual method as applying to a particular Culture only.

 DatapointAttribute Used to mark a field for use as a datapoint when executing a theory within the same fixture that requires an argument of the field's Type.

 DatapointsAttribute Used to mark an array as containing a set of datapoints to be used executing a theory within the same fixture that requires an argument of the Type of the array elements.

 DescriptionAttribute Attribute used to provide descriptive text about a test case or fixture.

 DirectoryAssert Summary description for DirectoryAssert

 ExpectedExceptionAttribute ExpectedExceptionAttribute

 ExplicitAttribute ExplicitAttribute marks a test or test fixture so that it will only be run if explicitly executed from the gui or command line or if it is included by use of a filter. The test will not be run simply because an enclosing suite is run.

 FileAssert Summary description for FileAssert.

 GlobalSettings GlobalSettings is a place for setting default values used by the framework in performing asserts.

 Guard Class used to guard against unexpected argument values by throwing an appropriate exception.

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

 IgnoreAttribute Attribute used to mark a test that is to be ignored. Ignored tests result in a warning message when the tests are run.

 IgnoreException Thrown when an assertion failed.

 InconclusiveException Thrown when a test executes inconclusively.

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

 Iz The Iz class is a synonym for Is intended for use in VB, which regards Is as a keyword.

 List The List class is a helper class with properties and methods that supply a number of constraints used with lists and collections.

 ListMapper ListMapper is used to transform a collection used as an actual argument producing another collection to be used in the assertion.

 MaxTimeAttribute Summary description for MaxTimeAttribute.

 PairwiseAttribute Marks a test to use pairwise join of any argument data provided. NUnit will attempt too excercise every pair of argument values at least once, using as small a number of test cases as it can. With only two arguments, this is the same as a combinatorial join.

 PlatformAttribute PlatformAttribute is used to mark a test fixture or an individual method as applying to a particular platform only.

 PropertyAttribute PropertyAttribute is used to attach information to a test as a name/value pair..

 RandomAttribute RandomAttribute is used to supply a set of random values to a single parameter of a parameterized test.

 Randomizer Randomizer returns a set of random values in a repeatable way, to allow re-running of tests if necessary.

 RangeAttribute RangeAttribute is used to supply a range of values to an individual parameter of a parameterized test.

 RepeatAttribute RepeatAttribute may be applied to test case in order to run it multiple times.

 RequiredAddinAttribute RequiredAddinAttribute may be used to indicate the names of any addins that must be present in order to run some or all of the tests in an assembly. If the addin is not loaded, the entire assembly is marked as NotRunnable.

 RequiresMTAAttribute Marks a test that must run in the MTA, causing it to run in a separate thread if necessary. On methods, you may also use MTAThreadAttribute to serve the same purpose.

 RequiresSTAAttribute Marks a test that must run in the STA, causing it to run in a separate thread if necessary. On methods, you may also use STAThreadAttribute to serve the same purpose.

 RequiresThreadAttribute Marks a test that must run on a separate thread.

 SequentialAttribute Marks a test to use a sequential join of any argument data provided. NUnit will use arguements for each parameter in sequence, generating test cases up to the largest number of argument values provided and using null for any arguments for which it runs out of values. Normally, this should be used with the same number of arguments for each parameter.

 SetCultureAttribute Summary description for SetCultureAttribute.

 SetUICultureAttribute Summary description for SetUICultureAttribute.

 SetUpAttribute SetUpAttribute is used in a TestFixture to identify a method that is called immediately before each test is run. It is also used in a SetUpFixture to identify the method that is called once, before any of the subordinate tests are run.

 SetUpFixtureAttribute Attribute used to mark a class that contains one-time SetUp and/or TearDown methods that apply to all the tests in a namespace or an assembly.

 StringAssert Basic Asserts on strings.

 SuccessException Thrown when an assertion failed.

 SuiteAttribute Attribute used to mark a static (shared in VB) property that returns a list of tests.

 TearDownAttribute Attribute used in a TestFixture to identify a method that is called immediately after each test is run. It is also used in a SetUpFixture to identify the method that is called once, after all subordinate tests have run. In either case, the method is guaranteed to be called, even if an exception is thrown.

 TestAttribute 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.

 TestCaseAttribute TestCaseAttribute is used to mark parameterized test cases and provide them with their arguments.

 TestCaseData The TestCaseData class represents a set of arguments and other parameter info to be used for a parameterized test case. It provides a number of instance modifiers for use in initializing the test case. Note: Instance modifiers are getters that return the same instance after modifying it's state.

 TestCaseSourceAttribute FactoryAttribute indicates the source to be used to provide test cases for a test method.

 TestContext Provide the context information of the current test

 TestDetails Provides details about a test

 TestFixtureAttribute

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

 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.

 Text Helper class with static methods used to supply constraints that operate on strings.

 TextMessageWriter TextMessageWriter writes constraint descriptions and messages in displayable form as a text stream. It tailors the display of individual message components to form the standard message format of NUnit assertion failure messages.

 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.

 TimeoutAttribute Used on a method, marks the test with a timeout value in milliseconds. The test will be run in a separate thread and is cancelled if the timeout is exceeded. Used on a method or assembly, sets the default timeout for all contained test methods.

 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.

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

 MessageMatch Enumeration indicating how the expected message parameter is to be used

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

 TestState The ResultState enum indicates the result of running a test

 TestStatus The TestStatus enum indicates the result of running a test

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

 ParameterDataAttribute Abstract base class for attributes that apply to parameters and supply data for the parameter.

 TestActionAttribute Provide actions to execute before and after tests.

 IExpectException Interface implemented by a user fixture in order to validate any expected exceptions. It is only called for test methods marked with the ExpectedException attribute.

 INUnitEqualityComparer

 INUnitEqualityComparer`1

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

 ITestCaseData The ITestCaseData interface is implemented by a class that is able to return complete testcases for use by a parameterized test method. NOTE: This interface is used in both the framework and the core, even though that results in two different types. However, sharing the source code guarantees that the various implementations will be compatible and that the core is able to reflect successfully over the framework implementations of ITestCaseData.
