Run/Debug Configuration: NodeUnit

Node interpreter

In this field, specify the Node.js interpreter to use.

If you choose the Project alias, PyCharm will automatically use the project default interpreter from the Node interpreter field on the Node.js page . In most cases, PyCharm detects the project default interpreter and fills in the field itself.

You can also choose another configured local or remote interpreter or click and configure a new one.

Working Directory

In this field, specify the folder to find tests under. This can be the project root folder or the parent directory for the test folder. Type the path manually or click Browse and select the location in the dialog, that opens.

Environment Variables

In this field, specify the environment variables for the Node.js executable file, if applicable. Click Browse to the right of the field and configure a list of variables in the Environment Variables dialog, that opens:

• To define a new variable, click and specify the variable name and value.

• To discard a variable definition, select it in the list and click .

• Click OK, when ready

The definitions of variables are displayed in the Environment variables read-only field with semicolons as separators, for example:

• NODE_PATH: A :-separated list of directories prefixed to the module search path.

• NODE_MODULE_CONTEXTS: Set to 1 to load modules in their own global contexts.

• NODE_DISABLE_COLORS: Set to 1 to disable colors in the REPL.

Nodeunit Module

In this text box, specify the installation folder of the Nodeunit framework. Type the path manually or click and choose the folder in the dialog box that opens.

Run

From this drop-down list, choose the scope of tests to execute. The available options are:

• All test files in the directory: choose this option to run all the test files in a folder and specify the path to this folder relative to the working directory.

• Test file: choose this option to execute tests from a specific file and type the path to this file relative to the working directory.

Name

Specify a name for the run configuration to quickly identify it among others when editing or running.

Allow multiple instances

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, PyCharm suggests stopping the running instance and starting another one. This is helpful when a run 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 PyCharm stores run configuration settings in .idea/workspace.xml.

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.
