Run/Debug Configuration: Jest
In this dialog, create configurations for running Jest tests.
Before you start
Download and install Node.js.
Jest-specific configuration settings
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
In this field, type the Node.js-specific command line options to be passed to the Node.js executable file. The acceptable options are:
In this field, specify the location of the jest, react-scripts, react-script-ts, react-super-scripts, or react-awesome-scripts package.
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.
In this field, type the Jest CLI options to be passed to Jest. For example, add a
In this field, optionally specify the environment variables for executing commands.
| In this area, specify the tests to be executed. The available options are: |
When you edit a run configuration (but not a run configuration template), you can specify the following options:
In this field, specify the name for the run/debug configuration. The name will help you identify the created configuration when you choose to edit it later, or when you invoke it, for example, from the Run popup (Shift+Alt+F10).
Select this checkbox to make the run/debug configuration available to other team members.
If the directory-based project format is used, the settings for a run/debug configuration are stored in a separate .xml file in the .idea\runConfigurations folder if the run/debug configuration is shared, or in the .idea\workspace.xml file otherwise.
If the file-based format is used, the settings are stored in the .ipr file for shared configurations, or in the .iws file otherwise.
Allow running in parallel
If this checkbox is selected, it is possible to launch a run configuration multiple times in parallel instead of rerunning it. Each runner will start in its own tab of the Run Tool Window or Debug Tool Window.
When disabled, every time a new instance of the run/debug configuration is launched, IntelliJ IDEA checks the presence of the other instances of the same run/debug configuration, and displays a confirmation dialog. If you click OK in the confirmation dialog, the first instance of the runner will be stopped, and the next one will take its place. This makes sense when launching two instances of run/debug configurations of the same type consumes too much of the CPU and memory resources..
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.
Create a run/debug configuration.
Delete the selected run/debug configuration. Note that you cannot delete default configurations.
Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.
The toolbar shows this button only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.
View and edit the template (that is, the default settings) for the selected run/debug configuration. The templates are displayed under the Templates node and used for newly created configurations.
Move the selected run/debug configuration up and down in the list.
The order of configurations in the list defines the order, in which the configurations appear when you choose a run/debug configuration.
Default templates of run/debug configurations are always sorted alphabetically.
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 options
In this area you can specify tasks that must be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.
Click this icon to add one of the following available tasks:
Click this icon to remove the selected task from the list.
Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.
Click these icons to move the selected task one line up or down in the list. (The tasks are performed in the order that they appear in the list.)
Show this page
Select this checkbox to show the run/debug configuration settings prior to actually starting the run/debug configuration.
Activate tool window
Otherwise, if the checkbox is cleared, the tool window isn't shown. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing Alt+4 or Alt+5.
