Getting access to the Run/Debug Configuration: Jest dialog

Install and enable the Node.js plugin. The plugin is not bundled with IntelliJ IDEA, but it can be installed from the JetBrains plugin repository as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.
Download and install the Node.js runtime environment that contains the Node Package Manager(npm).

Jest-specific configuration settings

Item	Description
Configuration file	In this field, optionally specify the `jest.config` file to use: choose the relevant file from the drop-down list, or click and choose it in the dialog that opens, or just type the path in the text box. If the field is empty, IntelliJ IDEA looks for a `package.json` file with a `jest` key. The search is performed in the file system upwards from the working directory. If no appropriate `package.json` file is found, then the Jest default configuration is used.
Node interpreter	In this field, specify the Node.js interpreter to use. Choose one of the configured interpreters or click and configure a new one as described in Configuring Node.js Interpreters. If you have appointed one of the installations as default, the field displays the path to its executable file.
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. All references in the starting Node.js application file, for example, imports, will be resolved relative to this folder, unless such references use full paths. By default, the field shows the project root folder. To change this predefined setting, choose the desired folder from the drop-down list, or type the path manually, or click the Browse button and select the location in the dialog box, that opens.
Jest options	In this text box, type the Jest CLI options to be passed to Jest. For example, add a `--watch` flag to turn on the autotest-like runner. As a result, any test in the current run configuration restarts automatically on changing the related source code, without clicking the Rerun button .
Environment variables	In this field, optionally specify the environment variables for executing commands.

Toolbar

Item	Shortcut	Description
	`Alt+Insert`	Click this button to add a new configuration to the list.
	`Alt+Delete`	Click this button to remove the selected configuration from the list.
	`Ctrl+D`	Click this button to create a copy of the selected configuration.
	Edit defaults	Click this button to edit the default configuration templates. The defaults are used for newly created configurations.
or	`Alt+Up` or `Alt+Down`	Use these buttons to move the selected configuration or folder up and down in the list. The order of configurations or folders in the list defines the order in which configurations appear in the Run/Debug drop-down list on the main toolbar.
	Move into new folder / Create new folder	Use this button to create a new folder. If one or more run/debug configurations are in focus, the selected run/debug configurations are automatically moved to the newly created folder. If only a category is in focus, an empty folder is created. Move run/debug configurations to a folder using drag-and-drop, or the buttons.
	Sort configurations	Click this button to sort configurations in alphabetical order.

Common options

Item Description

Name In this text box, specify the name of the current run/debug configuration. This field does not appear for the default run/debug configurations.

Defaults This node in the left-hand pane of the dialog box contains the default run/debug configuration settings. Select the desired configuration to change its default settings in the right-hand pane. The defaults are applied to all newly created run/debug configurations.

Select this check box 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.

This check box is not available when editing the run/debug configuration defaults.

Single instance only

If this check box is selected, this run/debug configuration cannot be launched more than once.

Every time a new 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 box. If you click OK in the confirmation dialog box, the first instance of the runner will be stopped, and the next one will take its place.

This makes sense when the usage of certain resources can cause conflicts, or when launching two run/debug configurations of the same type consumes too much of the CPU and memory resources.

If this check box is not selected, it is possible to launch as many instances of the runner as required. So doing, each runner will start in its own tab of the Run tool window.

Before launch

Specify which tasks must be performed before applying the run/debug configuration. The specified tasks are performed in the order they appear in the list.

Item	Keyboard shortcut	Description
	`Alt+Insert`	Click this icon to add a task to the list. Select the task to be added: Run External tool. Select this option to run an application which is external to IntelliJ IDEA. In the dialog that opens, select the application or applications that should be run. If the necessary application is not defined in IntelliJ IDEA yet, add its definition. For more information, see Configuring Third-Party Tools andExternal Tools. Make. Select this option to have the project or module compiled. The Make Module command will be carried out if a particular module is specified in the run/debug configuration, and the Make Project command otherwise. If an error occurs during the compilation, IntelliJ IDEA won't attempt to start the run/debug configuration. Make, no error check. The same as the Make option but IntelliJ IDEA will try to start the run/debug configuration irrespective of the compilation result. Build Artifacts. Select this option to have an artifact or artifacts built. In the dialog that opens, select the artifact or artifacts that should be built. See also, Working with Artifacts. Run Another Configuration. Select this option to have another run/debug configuration executed. In the dialog that opens, select the configuration to run. This option is available only if you have already at least one run/debug configuration in the current project. Run Ant target. Select this option to have an Ant target run. In the dialog that opens, select the target to be run. For more information, see Ant. Run Grunt task. Select this option to run a Grunt task. In the Grunt task dialog box that opens, specify the `Gruntfile.js` where the required task is defined, select the task to execute, and specify the arguments to pass to the Grunt tool.
