* This script tests that React Native end to end installation/bootstrap works for different platforms
* Available arguments:
* --ios - to test only ios application end to end
* --android - to test only android application end to end
* --js - to test that JS in the application is compilable
* --skip-cli-install - to skip react-native-cli global installation (for local debugging)
* --retries [num] - how many times to retry possible flaky commands: npm install and running tests, default 1
