Item | Description |
---|---|
Configuration file | In this field, optionally specify the jest.config file to use: select the relevant file from the list, or click and select it in the dialog that opens, or just type the path in the field. If the field is empty, IntelliJ IDEA looks for a package.json file with a |
Node interpreter | In this field, specify the Node.js interpreter to use. This can be a local Node.js interpreter or a Node.js on Windows Subsystem for Linux. |
Node options | In this field, type the Node.js-specific command-line options to be passed to the Node.js executable file. The acceptable options are:
|
Jest package | In this field, specify the location of the jest, react-scripts, react-script-ts, react-super-scripts, or react-awesome-scripts package. |
Working directory | In this field, specify the working directory of the application. By default, the Working directory field shows the project root folder. To change this predefined setting, specify the path to the desired folder or choose a previously used folder from the list. |

Common settings
When you edit a run configuration (but not a run configuration template), you can specify the following options:
Name | Specify a name for the run/debug configuration to quickly identify it when editing or running the configuration, for example, from the Run popup Alt+Shift+F10. |
Allow parallel run | Select to allow running multiple instances of this run configuration in parallel. By default, it is disabled, and when you start this configuration while another instance is still running, IntelliJ IDEA suggests to stop the running instance and start another one. This is helpful when a run/debug configuration consumes a lot of resources and there is no good reason to run multiple instances. |
Store as project file | Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project. By default, it is disabled, and IntelliJ IDEA stores run configuration settings in .idea/workspace.xml. |
Toolbar
The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your project as well as adjust default configurations templates.
Item | Shortcut | Description |
---|---|---|
Alt+Insert | Create a run/debug configuration. | |
Alt+Delete | Delete the selected run/debug configuration. Note that you cannot delete default configurations. | |
Ctrl+D | Create a copy of the selected run/debug configuration. Note that you create copies of default configurations. | |
The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent. | ||
Move into new folder / Create new folder. You can group run/debug configurations by placing them into folders. To create a folder, select the configurations within a category, click , and specify the folder name. If only a category is in focus, an empty folder is created. Then, to move a configuration into a folder, between the folders or out of a folder, use drag or and buttons. To remove grouping, select a folder and click . | ||
Click this button to sort configurations in the alphabetical order. |
Before launch
In this area, you can specify tasks to be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.

Otherwise, if the checkbox is cleared, the tool window is hidden. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing Alt+4 or Alt+5. |
