# Creating JavaScript Unit Tests

CLion integrates with most popular JavaScript unit testing frameworks and provides rich coding assistance for writing JavaScript unit tests. To get framework-aware coding assistance, download the desired framework and [configure it as a CLion JavaScript library](configuring-javascript-libraries.html).

Procedure: Create JavaScript unit tests

1. Create a separate folder for tests (`File | New | Directory`) next to the `src` folder. The name of this folder depends on the test framework you are using.

2. Mark `tests` as a test source folder.

3. For each production file, create a separate test file by choosing (`File | New | JavaScript File` on the context menu of the folder for tests. The format of the test file name depends on the test framework you are using.
