The top E2E Maestro with React Native tips & techniques

A collection of practical tips and techniques that simplify your developer experience with the Maestro E2E framework!

1. Installing Maestro

Let’s add a new script to the package.json file:

{
  "scripts": {
    "install-maestro": "MAESTRO_VERSION=1.37.0 curl -Ls 'https://get.maestro.mobile.dev' | bash"
  }
}

I define the version we now support using the environment variable MAESTRO_VERSION. The use of the same version by our team and CI is guaranteed.

2. Identify the app as being run by Maestro.

When an app is run by e2e, we occasionally need to configure the behavior of the app:

1. Disable animation / pause video;
2. Stop sending analytics;
3. Turn off React Native LogBox LogBox.ignoreAllLogs().

For this case, you need to add arguments to a launchApp command

- launchApp:
    appId: "com.example.app"
    arguments: 
       isE2E: "true"

And then on JS side, using react-native-launch-arguments package you can access that arguments
