Properties

	Name	Description
	Context	Gets or sets an object that contains context variables that are available to the Web performance test at run time. (Inherited from WebTest.)

	Guid	Gets or sets a GUID that uniquely identifies each instance of a WebTest. (Inherited from WebTest.)

Methods

	Name	Description
	AddCommentToResult	Adds a comment to the Web performance test result that follows the most recently completed Web performance test request, transaction, or included Web performance test. (Inherited from WebTest.)
	AddDataSource(String, String, DataBindingAccessMethod, array<String[])	Adds a data source to the data collection that is contained by the Web performance test. (Inherited from WebTest.)
	AddDataSource(String, String, String, DataBindingAccessMethod, array<String[])	Adds a data source to the data collection that is contained by the Web performance test. (Inherited from WebTest.)
	AddDataSource(String, String, String, DataBindingAccessMethod, DataBindingSelectColumns, array<String[])	(Inherited from WebTest.)
	AddDataSourceBinding	Defines a binding relationship and adds it to the data source binding collection for the Web performance test. (Inherited from WebTest.)
	BeginCondition	(Inherited from WebTest.)
	BeginLoop	(Inherited from WebTest.)
	BeginTransaction	Starts a transaction timer by using the specified name. (Inherited from WebTest.)

Remarks

This should always be the base class for all coded Web performance tests that are written in languages that do not support Visual C# iterator-like syntax. To write a Web performance test in Visual C#, see WebTest for an example. To run a test outside Visual Studio 2005 Team System, see Running Automated Tests from the Command Line for more information.

This class must be inherited; it cannot be instantiated.

Notes to Inheritors

When you inherit from ThreadedWebTest, you must override Run.

Examples

The following is a coded Web performance test called MyCodedWebTest that inherits from ThreadedWebTest. The second request posts the form information that is contained in three controls back to the server.
