## Add testing to your `next` app using `jest`
[`jest`](https://facebook.github.io/jest/) is a testing framework for `react`. In this example we show how to use `jest` to do DOM-testing for react applications in `next`
`npm install --save-dev jest babel-jest enzyme`
* `jest` - The testing framework
* `babel-jest` - Babel preprocessor for test files
* `enzyme` - Mock render the elements
Add test script to the [recommended `package.json`](https://github.com/zeit/next.js#production-deployment)
__package.json__
```javascript
...
"scripts": {
"test": "jest",
}
```
