This is an assertion library for enzyme to simplify your tests, and make them more readable.

This library supports several testing frameworks including Jest and Jasmine.

Want to add support for another testing framework? Check out our contributing doc!

Readme's for each package:



$ git clone <this repo>
$ cd enzyme-matchers
$ npm install
$ lerna bootstrap



$ npm run lint


$ npm test


We want to make this assertion library as robust and complete as possible. If you think that there are missing features/assertions, please open a GitHub issue or even better - a PR.
