Running Nodeunit Tests

On this page:


WebStorm supports integration with the nodeunit framework thus enabling running unit test for Node.js applications.

This topic provides guidelines in Node.js-specific unit testing procedures. For general information on testing in WebStorm, see the Testing section.

Creating and running unit tests for Node.js applications

  1. Enable nodeunit support.
  2. Write the unit tests.
  3. To have WebStorm recognize the unit tests and detect the corresponding production source code, mark the folder where the unit tests are stored as a test folder.
  4. Create a run configuration of the type Nodeunit.
  5. Launch unit tests and monitor test results in the Run tool window.

Enabling unit testing for Node.js applications

  1. Make sure that the Node.js plugin is enabled. The plugin is activated by default. If the plugin is disabled, enable it on the Plugins page as described in Enabling and Disabling Plugins.
  2. Download and install the Node.js runtime environment.
  3. Download and install the nodeunit testing framework

Creating Nodeunit tests

  1. Create a folder called  test at the same level as the src folder
  2. Populate the test folder. For each production file, create a separate test file.
  3. Mark the folder where the tests are stored as test folder.

Creating a Nodeunit run configuration

  1. Open the Run/Debug Configuration dialog box by choosing Run | Edit Configurations on the main menu.
  2. Click the Add button new on the toolbar and select the Nodeunit configuration type.
  3. In the dialog box that opens, specify the following:
    1. The name to identify the configuration.
    2. The path to the Node.js installation to use.

      If you have appointed one of the installations as default, the field displays the path to its executable file.

    3. The working directory. This can be the project root folder or the parent directory for the test folder.
    4. The scope of tests to run.
      • To have WebStorm run all the test files in a folder, choose All JavaScript test files in the directory from the Run drop-down list. In the Directory field, provide the path to the test folder relative to the working directory.
      • To have a specific test executed, choose JavaScript test file from the Run drop-down list. In the JavaScript test file field, provide the path to the file relative to the working directory.
  4. Apply the changes and close the dialog box.
