GoLand 2020.2 Help

Run tests

Generally, GoLand runs and debugs tests in the same way as other applications, by running the run/debug configurations you have created. When doing so, it passes the specified test classes or methods to the test runner.

In many cases, you can initiate a testing session from a context menu. For this purpose, the Run and Debug commands are provided in certain context menus. For example, these commands are available for a test class, directory, or a package in the Project tool window. They are also available for a test class or method you are currently working on in the editor.

If you run a test for which there is no permanent run/debug configuration, a temporary configuration is created. You can then save such a configuration using the Run/debug configuration dialog if you want to reuse it later.

The tests run in the background, so you can execute several tests at the same time.

Each running configuration gets its own tab in the Run tool window (the Test Results tab). One tab can aggregate several tests.

Quick way

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

  • Place the caret at the test file to run all tests in that file, or at the test method, and press Ctrl+Shift+F10. Alternatively, click the gutter icon next to the test method.

    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.

  • To run all tests in a folder, select this folder in the Project tool window and press Ctrl+Shift+F10 or select Run Tests in 'folder' from the context menu.

Customizable way

When you run a test, GoLand 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.

    Running a run/debug configuration for tests

After GoLand 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 Exlpore test results.

Running all tests in a folder, stopping, and rerunning a single test

Stop tests

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

  • Click the Stop button (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.

    Hold Shift and click the Run button to choose whether you want to Run the tests again or Debug them.

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 GoLand, 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.

    This option is not available for Maven and Gradle run configurations for tests.

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.

    Debugging a test using the gutter icon

Run a run/debug configuration for tests

To run a run/debug configuration for a test, you must create the run/debug configuration. Read about creating a run/debug configuration for tests in Create run/debug configurations for tests.

  1. Click the Edit Run/Debug Configurations list and select configuration that you want to run.

  2. Click the Run button the Run button.

Run a run/debug configuration for tests

Run tests from the gutter

When you run a test from the gutter, you create a temporary run/debug configuration. To save this configuration, navigate to Run | Edit Configurations, select the grayed-out item in the configurations list, and click the Save Configuration button the Save Configuration button.

  1. Click the Run Test icon the Run Test icon in the gutter.

  2. Select Run <configuration_name>.
