To modify the application, check out src/App.js. You will find basic example tests for that file at src/__tests__/App.js.

To run the test suite, run npm test. There should be no additional setup required to run the tests, other than running and npm install prior to the first run.

To run the app in the iOS simulator, run the start command. Before running this, you will have to be sure you have followed the setup instructions provided by the React Native team.
