# Pick a browser

If the test or test suite you are running contains steps that work with a form (any step involving a UI), or any other UI test step element (such as Automated Service Catalog test steps), work with the Pick a Browser
dialog.

## Before you begin

You must have created the test you want to run.  
The [test
execution property](https://servicenow-prod.fluidtopics.net/kcx6hsY5387sFbfeJbFwlw "On the Properties form, you can set parameters that control how the system executes automated tests and test suites.") must be enabled. You must have an admin or atf_test_admin role to do so.  
Note:  
The test execution property is disabled by default to prevent running tests on a production system. Run tests only on development, test, and other sub-production instances.

Role required: atf_test_admin, atf_test_designer, or admin

## About this task

The Pick a Browser dialog appears after you click Run Test or Run Test Suite. The dialog asks you to choose among any currently-running test clients or start a new test runner.

## Procedure

1. Choose the browser in which the test or test suite should run or be rerun again in the case of failed tests.  
   All registered client test runners that are currently active appear in the Pick a Browser dialog. (Current session) indicates that the browser is currently running. 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.").
2. Click Manage your test runners here as needed to view all client test runners registered for the current user.  
   See [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.").
3. If you want to open a client test runner in this browser session, click Start a new test runner, which appears when client test runners are only available in other browsers for the current user.
4. Click the appropriate button to run the test.
   * If you are running a single test, click Run Test.
   * If you are running a test suite, click Run Test Suite.
   * If you are running failed tests again, click Re-run failed tests.
