Start a client test runner and view information about test runners and test
runs.
For information on how to work with test runners, see [Working with client test runners](https://servicenow-prod.fluidtopics.net/RCkgkemnippD_sUkq2mTnw "If an automated test includes steps that involve a form or any other user-interface (UI) element, it runs those steps in a browser tab or window called a test runner or client test runner.").
* **[Client test runner](https://servicenow-prod.fluidtopics.net/W23zq0IdqARVOxVw~WErzQ)**   
  The Client Test Runner opens a browser window or tab for running manually-started client automated tests.
* **[Scheduled client test runner](https://servicenow-prod.fluidtopics.net/5X0VrZPhfbo5erAFbIV6ow)**   
  The Scheduled Client Test Run opens a browser window for running scheduled client automated tests.
* **[Active manual test runners](https://servicenow-prod.fluidtopics.net/bI6Ufx1jJxlg9DAnGUQ6rQ)**   
  View the client test runners table filtered to show only those runners available to run manually-started tests.
* **[Active scheduled test runners](https://servicenow-prod.fluidtopics.net/W64zfNuZM0etZuy3~oIRAw)**   
  View the client test runners table filtered to show only those runners available to run tests to be started by a schedule.
* **[Waiting/running test runs](https://servicenow-prod.fluidtopics.net/S1O6XRIYcDpN2ThTiPvNkA)**   
  The Waiting/Running Test Run module opens a list of records showing the tests waiting to be run.
* **[Waiting/running suite runs](https://servicenow-prod.fluidtopics.net/cAAsAjw54~Kfjj7cfiFSBA)**   
  The Waiting/Running Suite Runs module opens a list of records showing the test suites waiting to be run.
* **[Allowed client error records](https://servicenow-prod.fluidtopics.net/JEV1fZp0ZntPKsbQva5YXw)**   
  Review the list of existing Allowed Client Error \[sys_atf_whitelist\] records to see which client errors produce warnings and which are ignored. Modify existing Allowed Client Error records as needed or create new ones.
* **[Reported client errors](https://servicenow-prod.fluidtopics.net/sasxSkQrOYLhqmZEUydxRA)**   
  The Reported Client Error module lists test logs across all tests that are client errors and have failed. You can review individual test log records, and allowed client errors as needed to prevent them from adversely impacting future test executions.
