Generally, IntelliJ IDEA 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.
Running or debugging a test
To run or debug a test, follow these general steps:
To start running or debugging a test, you can use the main toolbar, or a context menu in the Project tool window or in the editor:
- Using the main toolbar:
- Select the necessary run/debug configuration from the list on the main toolbar.
- Click Run or Debug to the right of the list. (Alternatively, choose Run | Run (Shift+F10) or Run | Debug (Shift+F9) from the main menu.)
- Using a context menu:
Right-click a test class in the Project tool window, or open it in the editor, and right-click the background. On the context menu, choose Run < class name> or Debug....
