Validation rules help verify that a Web application is working correctly by validating the existence of text, tags, or attributes on the page returned by a Web request. Validation rules can also verify the amount of time it takes a request to finish, and the existence of form fields and their values. For more information, see Using Validation and Extraction Rules in Web Performance Tests.
You add validation rules to Web performance tests in the Web Performance Test Editor. For more information about how to edit a Web performance test, see Customizing Web Performance Test Recordings Using Web Performance Test Editor.
