vitest-browser-vue v0.0.1

vitest-browser-vue

Render Vue components in Vitest Browser Mode. This library follows testing-library principles and exposes only locators and utilities that encourage you to write tests that closely resemble how your Vue components are used.

Requires vitest and @vitest/browser 2.1.0 or higher.

import { render } from 'vitest-browser-vue'
import { expect, test } from 'vitest'

test('counter button increments the count', async () => {
  const screen = render(Component, {
    props: {
      initialCount: 1,
    }
  })

  await screen.getByRole('button', { name: 'Increment' }).click()

  await expect.element(screen.getByText('Count is 2')).toBeVisible()
})

vitest-browser-vue also automatically injects render and cleanup methods on the page. Example:

// vitest.config.ts
import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    // if the types are not picked up, add `vitest-browser-vue` to
    // "compilerOptions.types" in your tsconfig or
    // import `vitest-browser-vue` manually so TypeScript can pick it up
    setupFiles: ['vitest-browser-vue'],
  },
})

import { page } from '@vitest/browser/context'

test('counter button increments the count', async () => {
  const screen = page.render(Component, {
    props: {
      initialCount: 1,
    }
  })

  screen.cleanup()
})

Unlike @testing-library/vue, vitest-browser-vue cleans up the component before the test starts instead of after, so you can see the rendered result in your UI. To avoid auto-cleanup, import the render function from vitest-browser-vue/pure.
