Microsoft.VisualStudio.TestTools.UnitTesting Namespace ()

Team Test API

Microsoft.VisualStudio.TestTools.UnitTesting Namespace

The Microsoft.VisualStudio.TestTools.UnitTesting namespace supplies classes that provide unit testing support. This namespace contains many attributes that identify test information to the test engine regarding data sources, order of method execution, program management, agent/host information, and deployment data. The Microsoft.VisualStudio.TestTools.UnitTesting namespace also contains custom unit testing exceptions.

To read a walkthrough of the unit test framework, go to the MSDN Library and search for the following article, "A Unit Testing Walkthrough with Visual Studio Team Test".

Classes

	Class	Description
	AssemblyCleanupAttribute	Identifies a method that contains code to be used after all tests in the assembly have run and to free resources obtained by the assembly. This class cannot be inherited.
	AssemblyInitializeAttribute	Identifies a method that contains code to be used before all tests in the assembly have run and to allocate resources obtained by the assembly. This class cannot be inherited.
	Assert	Verifies conditions in unit tests using true/false propositions.
	AssertFailedException	Used to indicate failure for a test.
	AssertInconclusiveException	Used to indicate that a test is not yet implemented.
	BaseShadow	This class is used by the publicize method to help you test private types.
	ClassCleanupAttribute	Identifies a method that contains code to be used after all the tests in the test class have run and to free resources obtained by the test class. This class cannot be inherited.
	ClassInitializeAttribute	Identifies a method that contains code that must be used before any of the tests in the test class have run and to allocate resources to be used by the test class. This class cannot be inherited.
	CollectionAssert	Verifies true/false propositions associated with collections in unit tests.
	CssIterationAttribute	Represents the project iteration to which this test corresponds. This class cannot be inherited.
	CssProjectStructureAttribute	Represents the node in the team project hierarchy to which this test corresponds.
	DataSourceAttribute	Provides data source-specific information for data-driven testing. This class cannot be inherited.
	DataSourceElement	Represents a data source element as an XML tag within a configuration file.
	DataSourceElementCollection	Represents an XML element that contains a collection of child DataSourceElement objects.
	DeploymentItemAttribute	Used to specify deployment items such as files or directories for per-test deployment. This class cannot be inherited.
	DescriptionAttribute	Used to specify the description of the test. This class cannot be inherited.
	ExpectedExceptionAttribute	Indicates that an exception is expected during test method execution. This class cannot be inherited.
	GenericParameterHelper	This class is a placeholder for use with generics. It helps you test generic types by letting you pass non-specific type arguments.
	HostTypeAttribute	Used to specify the type of host that this unit test will run in. This class cannot be inherited.
	IgnoreAttribute	Indicates that a specific test should not be run. This class cannot be inherited.
	InternalTestFailureException	The exception that is thrown to indicate an internal failure for a test.
	OwnerAttribute	Used to specify the person responsible for maintaining, running, and/or debugging the test. This class cannot be inherited.
	PriorityAttribute	Used to specify the priority of a unit test. This class cannot be inherited.
	PrivateObject	Allows test code to call methods and properties on the code under test that would be inaccessible because they are not public.
	PrivateType	Represents the type of a private class that gives access to private static implementations.
	ShadowingAttribute	Do not use this class.
	StringAssert	Verifies true/false propositions associated with strings in unit tests.
	TestClassAttribute	Used to identify classes that contain test methods. This class cannot be inherited.
	TestCleanupAttribute	Identifies a method that contains code that must be used after the test has run and to free resources obtained by all the tests in the test class. This class cannot be inherited.
	TestConfiguration	Provides access to a TestConfigurationSection that represents the microsoft.visualstudio.testtools section in an app.config file.
	TestConfigurationSection	Provides access to data source configuration data.
	TestContext	Used to store information that is provided to unit tests.
	TestInitializeAttribute	Identifies the method to run before the test to allocate and configure resources needed by all tests in the test class. This class cannot be inherited.
	TestMethodAttribute	Used to identify test methods. This class cannot be inherited.
	TestPropertyAttribute	Establishes a test specific property on a method. This class cannot be inherited.
	TimeoutAttribute	Used to specify the time-out period of a unit test.
	UnitTestAssertException	This is the base class for unit test exceptions.
	WebServiceHelper	Contains helper methods for Web service testing.
	WorkItemAttribute	Used to specify a work item associated with a test.

Delegates

	Delegate	Description
	BaseShadow..::.ElementConverter	Do not use this delegate.

Enumerations

	Enumeration	Description
	DataAccessMethod	Specifies constants that indicate how data rows are accessed in data-driven testing.
	UnitTestOutcome	Use UnitTestOutcome to programmatically determine the outcome of a test that has run or is currently running.
