Enzyme React 16 adapter setup

Easy way to setup enzyme for React 16 in Jest.

Instalation

``bash


Using yarn

yarn add --dev enzyme react-test-renderer enzyme-adapter-react-16 enzyme-react-16-adapter-setup

Or using npm

npm install --dev enzyme react-test-renderer enzyme-adapter-react-16 enzyme-react-16-adapter-setup
`

Setup

The idea of this package is to make a file in order to set up enzyme.

The easyest way is to use jest's setupFiles. Make sure your package.json includes the following:

`json
{
// ...
"jest": {
// ...
"setupFiles": [
"raf/polyfill",
"enzyme-react-16-adapter-setup"
]
}
}
`

Note: The example also adds _requestAnimationFrame_ polyfill, if you are testing with _jsdom_, probabably you'll need it. In order to install it just do the following:

`bash


Using yarn

yarn add --dev raf

Or using npm

npm install --dev raf
`

$3

If you are using _Create React App_, you won't be able to use jest's setupFiles. You'll need to create the file src/setupTests.js with the following content:

`js
// src/setupTests.js
import 'raf/polyfill';
import 'enzyme-react-16-adapter-setup';
`

Note: You'll also have to add a _requestAnimationFrame_ polyfill as _jsdom_ doesn't provide one:
`bash


Using yarn

yarn add --dev raf

Or using npm

npm install --dev raf
