Resolving npm run test Task Issues in VSCode: How to Prevent Yarn Injection

If you’re a developer who relies on Visual Studio Code (VSCode) for your projects, you may have encountered an annoying issue lately: when trying to run your backend tests using npm run test:backend, the command gets unexpectedly changed to yarn run test:backend. This problem can disrupt your workflow, especially if you don't have Yarn installed on your system. Let's dive into the solution to this issue and understand the steps to get everything back to normal.

The Problem: Unexpected Yarn Injection

Running backend tests in your Node.js application typically involves using the command:

However, as you've noted, there can be instances where executing this command through the Task Runner in VSCode leads to an error like:

This occurs because VSCode defaults to using Yarn as the package manager instead of npm. While many developers are comfortable with Yarn, it's essential to use the package manager that aligns with your project setup.

Why This Happened

This issue might have surfaced due to an auto-update in VSCode, which inadvertently changed the package manager setting. Fortunately, resetting this to use npm is straightforward and can save you considerable headaches down the line.

The Solution: Reconfigure VSCode Settings

To resolve the issue, you need to change the package manager setting back to npm. Follow these simple steps:

Open VSCode Settings: You can access the settings by clicking on the gear icon in the lower left corner of VSCode or by pressing Ctrl + , (or Cmd + , on macOS).

Search for Package Manager: In the search bar of the settings view, type "Use Yarn" or "npm.packageManager".

Change the Package Manager: Locate the setting that mentions “Use Yarn” and switch it to npm. This will reset VSCode to use npm for any task configurations.

Verify in tasks.json: Open your tasks.json file located in the .vscode folder of your project and ensure that it contains the correct configuration. Here's a sample configuration:

Conclusion

After making these adjustments in your settings, try running your backend tests again using:

You should find that VSCode executes it correctly without trying to inject Yarn into the command. This small but crucial change can significantly improve your coding experience and ensure your tasks run smoothly.

Additional Tips

If you ever switch between projects that use different package managers, remember to double-check your VSCode settings.

Keep your VSCode updated to avoid encountering similar issues in the future.

By following these steps, you should be back on track, running your tests without any interruptions or errors. Happy coding!
