1. Launch the case type or portal you want to test.
2. Open the Run time toolbar at the bottom right corner and click the Toggle Automation Recorder button.
3. Click the Create test case button and select whether you want to create a portal level test or a case type menu. When you select case type, a new case of that type is created.
4. In your portal or case type, an orange highlight appears when you hover over a testable element. Record the step for the test by clicking on the element. The interaction will be saved to the list of test steps.

• Clicking an element records an implicit assertion and can be seen by clicking on the gear icon next to the step in the test recorder.
• You can add an explicit assertion to the test by clicking the plus icon in the orange highlight. All of the possible assertion can be selected from the a list of available assertions.

1. Click the Stop and save test case button. Enter a name and description for the test on the New test case form. Test cases can be saved in a branch or a ruleset. Test cases can only be saved in a ruleset marked as a test ruleset. Once saved, the test case is available on the Scenario testing landing page.
2. After this you can check the test cases created in your Scenario test landing page (Configure > Application > Quality > Automated Testing > Scenario Testing > Test Cases).
