Hi @devin schumacher. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- I understand your confusion about the configuration and setup for testing in Nuxt using @nuxt/test-utils. Let me help clarify based on the information provided in the knowledge sources. Your understanding, as shown in the gist, is generally on the right track, but there are a few points we can clarify and expand upon: 1. Installation: Your installation step is correct. You need to install @nuxt/test-utils along with other dependencies. The Nuxt documentation (https://nuxt.com/docs/getting-started/testing#installation) recommends:

npm i --save-dev @nuxt/test-utils vitest @vue/test-utils happy-dom playwright-core

npm i --save-dev @nuxt/test-utils vitest @vue/test-utils happy-dom playwright-core

2. Configuration: You're correct that you need both a nuxt.config.ts and a vitest.config.ts file. However, let's clarify their contents: In your nuxt.config.ts, you should add the @nuxt/test-utils module:

export default defineNuxtConfig({
  modules: [
    '@nuxt/test-utils/module'
  ]
})

export default defineNuxtConfig({
  modules: [
    '@nuxt/test-utils/module'
  ]
})

This is optional but adds Vitest integration to your Nuxt DevTools as mentioned in the docs (https://nuxt.com/docs/getting-started/testing#unit-testing). For your vitest.config.ts, you should use the defineVitestConfig function from @nuxt/test-utils/config:

import { defineVitestConfig } from '@nuxt/test-utils/config'

export default defineVitestConfig({
  test: {
    environment: 'nuxt'
  }
})

import { defineVitestConfig } from '@nuxt/test-utils/config'

export default defineVitestConfig({
  test: {
    environment: 'nuxt'
  }
})

This sets up the Nuxt environment for your tests as shown in the documentation (https://nuxt.com/docs/getting-started/testing#unit-testing). 3. Test Files: Your understanding of test file naming is correct. Files ending with .nuxt.spec.ts or .nuxt.test.ts will use the Nuxt environment. Alternatively, you can add // @vitest-environment nuxt at the top of your test file as mentioned in the docs (https://nuxt.com/docs/getting-started/testing#using-a-nuxt-runtime-environment). 4. Helpers and Utilities: @nuxt/test-utils provides several helpers like mountSuspended, renderSuspended, and mockNuxtImport for unit testing as described in the documentation (https://nuxt.com/docs/getting-started/testing#-helpers). 5. End-to-End Testing: For E2E testing, @nuxt/test-utils supports various test runners including Vitest, Jest, Cucumber, and Playwright as mentioned in the docs (https://nuxt.com/docs/getting-started/testing#end-to-end-testing). One key thing to note is that you can't mix unit testing and E2E testing in the same file due to different environment requirements as stated in the documentation (https://nuxt.com/docs/getting-started/testing#conflict-with-end-to-end-testing). Your understanding is generally correct, but remember that the exact configuration might vary depending on your specific needs and the type of testing you're doing (unit, E2E, or both). For a more comprehensive understanding, I recommend watching the YouTube video by Alexander Lichter (https://www.youtube.com/watch?v=yGzwk9xi9gU) which provides a primer on testing in Nuxt and might help clarify how all these pieces fit together. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

wtf my understanding is jsdom and happy-dom are Dom Renderers, not runtimes, but the nuxt docs says "you can choose between happy-dom and jsdom for a runtime Nuxt environment" which is either wrong, or confusing, or i dont know what im talking about

devin schumacherOP•3w ago

Cue•3w ago

The dom is a runtime environment

devin schumacherOP•2w ago

what am i missing here?

Cue•2w ago

The DOM itself isn’t a runtime environment. But in the context of Nuxt, it is its runtime environment. That’s where the confusion is here.
