AfterTestActionCommand TestActionAfterCommand handles the AfterTest method of a single TestActionItem, provided the items BeforeTest has been run.

 BeforeTestActionCommand TestActionBeforeCommand handles the BeforeTest method of a single TestActionItem, relying on the item to remember it has been run.

 ConstructFixtureCommand ConstructFixtureCommand constructs the user test object if necessary.

 DisposeFixtureCommand OneTimeTearDownCommand performs any teardown actions specified for a suite and calls Dispose on the user test object, if any.

 EmptyTestCommand EmptyTestCommand is a TestCommand that does nothing. It simply returns the current result from the context when executed. We use it to avoid testing for null when executing a chain of DelegatingTestCommands.

 FixturePerTestCaseCommand ConstructFixtureCommand constructs the user test object if necessary.

 MaxTimeCommand adjusts the result of a successful test to a failure if the elapsed time has exceeded the specified maximum time allowed.

 OneTimeSetUpCommand OneTimeSetUpCommand runs any one-time setup methods for a suite, constructing the user test object if necessary.

 OneTimeTearDownCommand OneTimeTearDownCommand performs any teardown actions specified for a suite and calls Dispose on the user test object, if any.

 SetUpTearDownCommand SetUpTearDownCommand runs SetUp methods for a suite, runs the test and then runs TearDown methods.

 SetUpTearDownItem SetUpTearDownItem holds the setup and teardown methods for a single level of the inheritance hierarchy.

 TestActionCommand TestActionCommand handles a single ITestAction applied to a test. It runs the BeforeTest method, then runs the test and finally runs the AfterTest method.

 TestActionItem TestActionItem wraps a single execution of an ITestAction. Its primary purpose is to track whether the BeforeTest method has been called and suppress calling the AfterTest method if it has not. This is necessary when ITestActions are used before and after a CompositeWorkItem, since the OneTimeSetUpCommand and OneTimeTearDownCommand are separate command chains. By sharing a TestActionItem between the setup and teardown chains, the two calls can be coordinated.

 TestMethodCommand TestMethodCommand is the lowest level concrete command used to run actual test cases.

 TheoryResultCommand TheoryResultCommand adjusts the result of a Theory so that it fails if all the results were inconclusive.

 TimeoutCommand creates a timer in order to cancel a test if it exceeds a specified time and adjusts the test result if it did time out.

 AfterTestCommand AfterCommand is a DelegatingTestCommand that performs some specific action after the inner command is run.

 BeforeAndAfterTestCommand TestActionCommand handles a single ITestAction applied to a test. It runs the BeforeTest method, then runs the test and finally runs the AfterTest method.

 BeforeTestCommand BeforeTestCommand is a DelegatingTestCommand that performs some specific action before the inner command is run.

 DelegatingTestCommand DelegatingTestCommand wraps an inner TestCommand. Derived classes may do what they like before or after running the inner command.

 TestCommand TestCommand is the abstract base class for all test commands in the framework. A TestCommand represents a single stage in the execution of a test, e.g.: SetUp/TearDown, checking for Timeout, verifying the returned result from a method, etc. TestCommands may decorate other test commands so that the execution of a lower-level command is nested within that of a higher level command. All nested commands are executed synchronously, as a single unit. Scheduling test execution on separate threads is handled at a higher level, using the task dispatcher.
