• ./utils/add-sepolia.sh
• npm run e2e

We are using Maestro since it's the only recommended option for Expo EAS. Test flows are located in mobile/.maestro/. We are also relying on Expo EAS for builds, so a generic workflow to run e2e tests on USB-connected Android device would be:

• get a list of builds from EAS: eas build:list (optionally trigger the build manually first: eas build --platform android --profile preview --message="debug smth" --no-wait)
• Note the Artifacts field, and download the one you need: wget https://expo.dev/artifacts/eas/example.apk
• make sure Android device is connected and in dev mode, then install the apk: adb install example.apk
• run the tests npm run e2e (from mobile/ dir)

• local android build: eas build --platform android --profile preview --local
• ext build: npm run build
