# Client test runner

The Client Test Runner opens a browser window or tab for running manually-started client automated tests.

You can toggle a client test runner to act as either a manual or scheduled client test runner. For more information about scheduling test suites, see [Schedule an automated test suite](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/automated-test-framework-atf/atf-sched-suite-steps.md).
