How to: Add a Validation Rule to a Web Test

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 About Validation Rules.

You add validation rules to Web tests in the Web Test Editor. For more information about how to edit a Web test, see How to: Edit an Existing Web Test.

Procedure

To add a validation rule to a Web test

  1. Open a Web test.

    For more information about how to create a Web test, see Creating a Web Test.
