You can add if/then branching logic to Web performance tests and then assign specific conditional rules and properties. For example, you could create a condition on a Web request to verify if a cookie is present.

NoteNote

You can also add looping conditional logic, which can run a Web performance test or a Web request in a Web performance test multiple times to verify if a condition is true or false. For more information, see How to: Add Loops to Web Performance Tests Requests.

To insert a conditional branch rule into a Web performance test

  1. Open a solution that contains a test project. Make sure that the test project contains a Web performance test and then open the Web performance test.

  2. Select either the Web performance test or the Web request where you want to insert a conditional branch. Right-click and select Insert Condition.

  3. In the Add Conditional Rule and Items to Condition dialog box, under Select a rule, choose the type of conditional rule you want to use in the if/then branching logic. For the descriptions of the different kinds of conditional rules that are available, see the table in this procedure.

  4. Under Properties for selected rule, specify the property settings according to your needs.

    For example, you could use the Last Response Code rule to verify that the response code is returning 200 - OK.

    The conditional rules and their associated properties are included in the table in this procedure.

    NoteNote

    The descriptions for the conditional rules and associated properties are also displayed in the Add Conditional Rule and Items to Condition dialog box. As with the Properties Window, You can use the properties toolbar buttons in the Add Conditional Rule and Items to Condition dialog box to sort the properties by Categorized, Alphabetical and by Property Pages.
