## create-react-app-for-testing
create-react-app comes with Jest which is awesome, but sometimes you need a real DOM/browser to test with. Here's a quick way to get up and running testing your app.

1. Create a *separate* app for testing, using create-react-app:
```
create-react-app tests
cd tests
```

2. Modify the index.html to include the Jasmine spec runner (see index.html below)
3. Modify the index.js to just run your tests rather than bootstrap a React app. (see index.js below)

Happy testing!
