Error: Vitest failed to access its internal state

Hello guys! I was writing some tests, and I suddenly get stucked with this error. My config does not have anything fancy (do not ask for a reproduction case), as it consists of a running nuxt app, with @nuxt/test-utils setup as mentionned by the doc. All my test files are located on *.spec.ts pattern, and I'm simply trying to run "npx nuxi dev". Does it rings someone bell's?

Hi @kogratte. 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 about your Vitest error with Nuxt testing. The error you're encountering, "Vitest failed to access its internal state," is not specifically mentioned in the provided documentation. However, there are a few points from the Nuxt testing documentation that might be relevant to your situation: 1. File naming: According to the Nuxt testing documentation (https://nuxt.com/docs/getting-started/testing#using-a-nuxt-runtime-environment), test files that use the Nuxt environment should have .nuxt. in their name (e.g., my-file.nuxt.test.ts or my-file.nuxt.spec.ts). Your files are named *.spec.ts, which might not trigger the Nuxt environment. 2. Environment configuration: You might need to explicitly set the Nuxt environment for your tests. The documentation suggests adding @vitest-environment nuxt as a comment at the top of your test files or setting environment: 'nuxt' in your Vitest configuration Nuxt testing documentation (https://nuxt.com/docs/getting-started/testing#using-a-nuxt-runtime-environment). 3. Configuration file: Ensure you have a proper vitest.config.ts file set up as shown in the Nuxt testing documentation (https://nuxt.com/docs/getting-started/testing#unit-testing). This file should use defineVitestConfig from @nuxt/test-utils/config. 4. Package.json configuration: Make sure your package.json has "type": "module" specified, or rename your Vitest config file appropriately (e.g., vitest.config.mts) Nuxt documentation PR (https://github.com/nuxt/nuxt/pull/26845). 5. Running tests: The command you're using, npx nuxi dev, is for running the Nuxt development server, not for running tests. To run Vitest tests, you typically use a command like npm run test or npx vitest, depending on how you've set up your scripts Nuxt testing documentation (https://nuxt.com/docs/getting-started/testing#using-vuetest-utils). Without more specific details about your setup, it's difficult to pinpoint the exact cause of the error. However, reviewing these points and ensuring your configuration aligns with the Nuxt testing documentation might help resolve the issue. If the problem persists after checking these points, you might need to provide more details about your specific setup or consider creating a minimal reproduction case to get more targeted assistance. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai This is not the right answer. Nuxt is autoimporting server utils as well as their tests. I need to exclude a pattern from being imported. How? @kapa.ai This is not the right answer.

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize for the misunderstanding in my previous answer. You're correct, and I'll provide a more relevant answer based on your specific question about excluding patterns from auto-imports in Nuxt. Nuxt does indeed auto-import server utils and their tests. To exclude a specific pattern from being auto-imported, you have a few options: 1. Using the ignore configuration: You can use the ignore array in your nuxt.config.ts file to specify patterns that should be ignored during the build process. This includes auto-imports. Here's how you can do it:

   export default defineNuxtConfig({
     ignore: [
       '**/*.spec.{js,ts}',  // Ignores all spec files
       '**/tests/**'         // Ignores everything in a tests directory
     ]
   })

   export default defineNuxtConfig({
     ignore: [
       '**/*.spec.{js,ts}',  // Ignores all spec files
       '**/tests/**'         // Ignores everything in a tests directory
     ]
   })

This configuration is mentioned in the Nuxt Configuration documentation (https://nuxt.com/docs/api/nuxt-config#ignore). 2. Using ignorePrefix: If your files follow a specific naming convention, you can use the ignorePrefix option. By default, it's set to '-', but you can change it:

   export default defineNuxtConfig({
     ignorePrefix: 'test-'
   })

   export default defineNuxtConfig({
     ignorePrefix: 'test-'
   })

This is documented in the Nuxt Configuration documentation (https://nuxt.com/docs/api/nuxt-config#ignoreprefix). 3. Disabling auto-imports: If you want more control, you can disable auto-imports completely and then manually import what you need. This can be done by setting imports.autoImport to false:

   export default defineNuxtConfig({
     imports: {
       autoImport: false
     }
   })

   export default defineNuxtConfig({
     imports: {
       autoImport: false
     }
   })

This option is mentioned in the Nuxt Auto-imports documentation (https://nuxt.com/docs/guide/concepts/auto-imports#disabling-auto-imports). 4. For server-specific utils: If you're specifically dealing with server utils, you might want to look into the Nitro configuration. Nitro is the server engine used by Nuxt, and it has its own auto-import system. However, the provided knowledge sources don't contain specific information about excluding patterns from Nitro's auto-imports. Remember that these configurations might affect other parts of your application, so use them cautiously and test thoroughly after making changes. If you need more specific control or if these options don't fully address your needs, you might need to explore more advanced configuration options or consider creating a custom Nuxt module to handle the exclusions. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai for me it seems it should be the default configuration. Could you report that?

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand your perspective on this matter. However, as an AI assistant, I don't have the ability to directly report issues or suggest changes to the Nuxt team. What I can do is provide you with information on how you can report this suggestion yourself. If you believe that excluding test files from auto-imports should be the default configuration in Nuxt, you can report this suggestion to the Nuxt team through their official GitHub repository. Here's how you can do it: 1. Visit the Nuxt GitHub Issues page (https://github.com/nuxt/nuxt/issues). 2. Click on "New Issue". 3. Choose the appropriate issue template, likely "Feature Request" in this case. 4. Fill out the template, explaining your suggestion that test files (e.g., *.spec.ts) should be excluded from auto-imports by default. 5. Provide your rationale for why this should be the default behavior. 6. Submit the issue. Remember to check if there's an existing issue or discussion about this topic before creating a new one. The Nuxt team and community are generally responsive to well-reasoned suggestions for improving the framework. In the meantime, you can use the configuration options I mentioned in my previous response to exclude your test files from auto-imports in your current projects. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
