How to Use Mocha Test Explorer in VSCode with Custom Test Directory

Are you struggling to configure Mocha Test Explorer in Visual Studio Code when your tests are located in a non-default folder? If your test files reside in a directory other than the conventional /test, such as /code_tests, don’t worry! This post will guide you through the process of configuring VSCode to recognize your custom test directory without needing to rename it.

Understanding the Problem

By default, Mocha Test Explorer expects tests to be found in a directory called /test. This can become a hassle if your test files are stored in a different folder. Changing the folder name is not always an ideal solution, especially if you’re collaborating with other developers or maintaining a specific project structure.

In the given scenario, you're using TypeScript with VSCode, and you find yourself needing to update the settings so that Mocha Test Explorer points to your /code_tests folder instead.

Solution Overview

To configure Mocha Test Explorer to read from your custom folder, you need to adjust your VSCode settings by editing the settings.json file. Follow the steps below to ensure your test configuration works correctly.

Step 1: Access the Settings File

Open VSCode.

Navigate to File Preferences Settings or use the shortcut Ctrl + , (Windows/Linux) or Cmd + , (Mac).

In the top right corner, click on the {} icon to open the settings in JSON format. This allows you to edit the configuration file directly.

Step 2: Update the settings.json

Now that you have access to the settings file, you will need to add two crucial lines to make Mocha Test Explorer recognize your /code_tests directory.

Add the Following Lines

mochaExplorer.require: This line configures Mocha to include the TypeScript Node compiler, allowing you to run TypeScript files directly.

mochaExplorer.files: Adjusting this line sets the path to your custom test folder, ensuring that Mocha looks for test files in code_tests instead of the default directory.

Step 3: Save and Restart VSCode

After making the above additions, save the settings.json file. To ensure the changes take effect, it is a good practice to restart VSCode. Once restarted, the Mocha Test Explorer should now recognize and run tests from your /code_tests directory seamlessly.

Conclusion

Configuring Mocha Test Explorer to look into your custom test directory is a straightforward process once you know where to adjust the settings. By updating the settings.json file, you can avoid renaming your directories while maintaining an organized project structure.

If you run into any issues, double-check your paths and the syntax in the settings.json file. Happy testing, and may your coding experience be smooth and productive!
