 ## Jest Tests
 
-[Jest](http://facebook.github.io/jest/) tests are JS-only tests run on the command line with node.  The tests themselves live in the `__tests__` directories of the files they test, and there is a large emphasis on aggressively mocking out functionality that is not under test for failure isolation and maximum speed.  You can run the existing React Native jest tests with `npm test` from the react-native root, and we encourage you to add your own tests for any components you want to contribute to.  See [`getImageSource-test.js`](https://github.com/facebook/react-native/blob/master/Examples/Movies/__tests__/getImageSource-test.js) for a basic example.

 Note: you may have to install/upgrade/link io.js and other parts of your environment in order for the tests to run correctly.  Check out the latest setup in [.travis.yml](https://github.com/facebook/react-native/blob/master/.travis.yml#L11-24)
