## What it is
The official component testing utility library for Vue 3, providing APIs to mount, interact with, and assert against Vue components in test environments. It is published as the @vue/test-utils npm package.

## Use cases
- unit test vue 3 components
- mount vue components in tests
- test vue component props and events
- write component tests with vitest for vue
- migrate from vue test utils v1 to v2

## When to choose
- you are writing unit or component tests for Vue 3 applications
- you need to mount, query, and interact with Vue components in a test runner like Vitest or Jest

## When to avoid
- you are testing Vue 2 applications (use Vue Test Utils v1 instead)
- you need full end-to-end browser testing rather than component-level tests (consider Cypress or Playwright)

## Facets
- artifact type: library

- function: testing, e2e-testing, mocking
- domain: frontend, web-development, testing, developer-tools
