How to use the HTTP Cookie Manager to help returning cookies received from the Web server?

For most Web applications, the Web server is expecting you to send back cookies received from the previous HTTP calls.

You can use the HTTP Cookie Manager to help returning cookies received from the Web server automatically as shown in this tutorial.

1. Start JMeter on your computer and open "\fyicenter\Facebook-Login-Test-6.jmx".

2. Right-click on the "Facebook Login Test Plan", and select "Add > Config Element > HTTP Cookie Manager". You see the "HTTP Cookie Manager" settings screen.

3. Set "Clear cookies each iteration" to be checked.

4. Drag and drop the "HTTP Cookie Manager" to move it above the "Login Test Case".

5. Save the test plan as "\fyicenter\Facebook-Login-Test-6.jmx" and run it.

6. View the "POST Login & Password" response data in a Web browser, you see an error on the returning page: "The password you’ve entered is incorrect." This is expected, because the user email address and password provided were wrong.

7. Add an Response Assertion for the "POST Login & Password" sampler with the following settings:

Name: Incorrect Password
Apply to: Main sample and sub-samples
Field to Test: Text Response
Pattern Matching Rules: Contains
Patterns to Test: The password you\\u2019ve entered is incorrect.

8. Save the test plan and run it again. This time, "POST Login & Password" will pass the assertion.
