In this field, type the Node.js-specific command-line options to be passed to the Node.js executable file. See Node Parameters for details.

Alternatively, type the path to executable file manually, or click Browse and select the location in the dialog, that opens.
From this list, choose the interface according to which the tests in the test folder are written. PhpStorm will recognize only tests that comply with the chosen interface. If during test execution PhpStorm runs against a test of another interface, the test session will be canceled with an error.

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, PhpStorm 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 PhpStorm stores run configuration settings in .idea/workspace.xml.
