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 gutter icon marks new tests.
The gutter icon marks successful tests.
The gutter icon marks failed tests.
To run all tests in a file, select this file in the Project tool window and then select Run 'All in <filename>' 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 Run/debug configurations.
Create a new run configuration or save a temporary one.
Use the configuration switcher on the main toolbar to select the configuration you want to run.
Click or press Shift+F10.
Create a test configuration
Open the Run/Debug Configuration dialog by doing one of the following:
From the configuration switcher on the main toolbar, select.
Press Alt+Shift+F10 and select Edit Configuration from the context menu.
Click on the toolbar and select the desired configuration type:
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 about analyzing test results, refer to Explore test results.
Run tests after commit
When you want to check that your changes wouldn't break the code before pushing them, you can do that by running tests as commit checks.
Set up test configuration
After you have set up the test configuration, the specified tests will run every time you make a commit.
Use the following options on the Run toolbar of the Test Runner tab:
Click or press Ctrl+F2 to terminate the process immediately.
Rerun a single test
Right-click a test on the Test Runner tab of the Run tool window and select Run 'test name'.
Rerun all tests in a session
Click on the Run toolbar or press Ctrl+F5 to rerun all tests in a session.
Rerun failed tests
Click 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 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 Rerun Automatically 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.
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.
Right-click the gutter icon next to the failed test and select Debug 'test name'.
The test will rerun in 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.
