Component testing utils for Vue 3.
- yarn:
yarn add @vue/test-utils --dev - npm:
npm install @vue/test-utils --save-dev
Get started with the documentation.
Check the migration guide. It's still a work in progress. If you find a problem or something that doesn't work that previously did in Vue Test Utils v1, please open an issue.
See the docs.
Get started by running yarn install. You can run the tests with yarn test. That's it!
This is table for those coming from VTU 1, comparing the two APIs. Some things are still a work in progress.
