WebTestContext.Item Property (String)
Gets or sets the value associated with the specified key from the WebTestContext object.
Assembly: Microsoft.VisualStudio.QualityTools.WebTestFramework (in Microsoft.VisualStudio.QualityTools.WebTestFramework.dll)
Context defined by environmental variables or a load test will override the item returned by this property. So if a Web performance test is running in a Load Test that contains a context called "myContext", a call to MyWebTestContext.Item("myContext") will return the value for the LoadTestContext.Item("myContext").
