test-utils wont register custom plugins
I'm currently migrating away from the auto imports and since the unit tests are not working anymore it seems like I need to switch to nuxt test utils (away from a custom setup with the vue test utils).
But now my custom nuxt plugins are not registered anymore (useNuxtApp does not include them). I just get
$myPlugin is not a function. Any ideas on how to debug this?3 Replies
Hi @luhu. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Based on the information provided in the knowledge sources, I can offer some insights and suggestions to help debug your issue with custom Nuxt plugins not being registered when using
@nuxt/test-utils. Here are a few points to consider:
1. Ensure correct setup:
Make sure you have properly set up @nuxt/test-utils in your project. This includes adding the necessary dependencies and configuring your vitest.config.ts file as described in the Testing documentation.
2. Use the Nuxt environment:
To ensure your Nuxt plugins are loaded, you need to use the Nuxt runtime environment for your tests. You can do this by either:
- Adding .nuxt. to your test file names (e.g., my-file.nuxt.test.ts)
- Adding @vitest-environment nuxt as a comment at the top of your test file
- Setting environment: 'nuxt' in your Vitest configuration

3. Check plugin format:
Ensure your plugins are using the correct format for Nuxt 3. Plugins should now use the defineNuxtPlugin helper and take only one argument (nuxtApp). For example:

4. Verify plugin registration:
Make sure your plugins are properly registered in your Nuxt configuration. In Nuxt 3, plugins in the plugins/ directory are automatically registered, so you don't need to list them in your nuxt.config file.
5. Debug with useNuxtApp:
You can use the useNuxtApp() composable to inspect the contents of your Nuxt app context within your tests. This might help you identify if your plugins are being registered correctly:

6. Check for errors:
Look for any error messages in your test output or browser console that might indicate why the plugins aren't being registered.
If you're still having issues after checking these points, it might be helpful to create a minimal reproduction of the problem and share it when asking for help in the Nuxt GitHub Discussions.
Remember, when migrating from auto-imports to explicit imports, you'll need to manually import any composables or utilities you're using in your tests.
If you need more specific help, please provide more details about your setup, including your vitest.config.ts, an example of one of your plugins, and the relevant parts of your test file.
