How to: Add "If Then" Branch Conditions to Web Performance Tests Requests

This topic applies to:

Visual Studio Ultimate	Visual Studio Premium	Visual Studio Professional	Visual Studio Express

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.

Adding a Conditional Rule

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.

   Note

   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.

   Conditional Rules and Associated Properties

   Conditional Rule	Rule Description	Properties
   Context Parameter Existence	Confirm the existence or absence of a context parameter.	Context Parameter Name Check for Existence
   Cookie Existence	Confirm the existence or absence of a cookie.	Web Page URI Cookie Name Check for Existence Cookie Domain Name (Optional) Cookie Path (Optional)
   Cookie Value Comparison	The condition is met when the provided string matched the value of the specified cookie.	Web Page URI Cookie Name Comparison Operator Value Ignore Case Use Regular Expression Cookie Domain Name (Optional) Cookie Path (Optional)
   Last Request Outcome	Confirm the outcome of the previous request.	Request Outcome
   Last Response Code	Confirm the HTTP status code of the previous response	Comparison Operator Response Code
   Numeric Comparison	The condition is met when the content of the provided context parameter satisfies the numeric comparison with the provided value.	Context Parameter Name Comparison Operator Value
   Probability Rule	The condition will be considered as met according to the provided percentage.	Context Parameter Name Percentage
   String Comparison	The condition is met when the provided string matches the content of the provided context parameter.	Context Parameter Name Comparison Operator Value Ignore Case Use Regular Expression

5. Under Items in Condition, use the drop-down list under Choose first item for condition and specify the first item that you want to use in the condition.

6. Click the drop-down list under Choose the last item for condition and specify the last item you want to use in the condition.

7. Click OK.

   After you have closed the Add Conditional Rule and Items to Condition dialog box, you see that your condition is now indicated by an icon in the Web Performance Test Editor.

   Note

   Later, you can edit the property settings that you specified for the rule by highlighting the condition in the Web Performance Test Editor and using the Properties Window.
