Run tests

Run a single test

If your tests don't require any specific actions before start and you don't want to configure additional options, such as code coverage, you can run them by using the following options:

  • Place the caret at the test, and press Ctrl+Shift+F10. Alternatively, click the gutter icon next to the test.

    The gutter icon changes depending on the state of your test:

    • The the Run button gutter icon marks new tests.

    • The the Run test icon gutter icon marks successful tests.

    • The the Rerun the Run button gutter icon marks failed tests.

    Run single test from the editor
  • To run all tests in a file, select this file in the Project tool window and select Run <file name> from its context menu.

Run tests via a run/debug configuration

When you run a test, WebStorm creates a temporary run configuration. You can save temporary run configurations, change their settings, share them with other members of your team. For more information, refer to Work with run/debug configurations.

  1. Create a new run configuration or save a temporary one.

  2. From the list on the main toolbar, select the configuration you want to run.

  3. Click the Run button or press Shift+F10.

Create a test configuration

  1. Open the Run/Debug Configuration dialog by doing one of the following:

    • From the list on the main toolbar, select Run | Edit Configurations.

    • From the main menu, select Run | Edit Configurations.

    • Press Alt+Shift+F10 and select Edit Configuration from the context menu.

  2. Click Add New Configuration on the toolbar and select the desired configuration type:

  3. In the dialog that opens, specify the test scope, configuration parameters, and activities to perform before test execution. Apply the changes and close the dialog.

After WebStorm finishes running your tests, it shows the results in the Run tool window on the Test Runner tab. For more information on how to analyze test results, refer to Explore test results.

Stop tests

Use the following options on the Run toolbar of the Test Runner tab:

  • Click the Stop button or press Ctrl+F2 to terminate the process immediately.

Rerun tests

Rerun a single test

  • To rerun a single test, right-click this test on the Test Runner tab of the Run tool window and select Run 'test name'.

Rerun all tests in a session

  • Click the Run button on the Run toolbar or press Ctrl+F5 to rerun all tests in a session.

Rerun failed tests

  • Click the Rerun Failed Tests button on the Run toolbar to rerun only failed tests.

    You can configure the IDE to trigger tests that were ignored or not started during the previous test run together with failed tests. Click the Settings button on the Test Runner toolbar and enable the Include Non-Started Tests into Rerun Failed option.

Rerun tests automatically

In WebStorm, you can enable the autotest-like runner: any test in the current run configuration restarts automatically after you change the related source code.

  • Click Toggle auto-test Toggle auto-test on the Run toolbar to enable the autotest-like runner.

Debug failed tests

If you don't know why a test fails, you can debug it.

  1. In the editor, click the gutter on the line where you want to set a breakpoint.

    There are different types of breakpoints that you can use depending on where you want to suspend the program. For more information, refer to Breakpoints.

  2. Right-click the the Rerun the Run button gutter icon next to the failed test and select Debug 'test name'.

    The test that has failed will be rerun in the debug mode. After that, the test will be suspended, allowing you to examine its current state.

    You can step through the test to analyze its execution in detail.
