fastlane/config/testing.yml
app_testing:
  enabled: true      # global switch (environment app_testing.enabled overrides it)
  blocking: true     # true = wait for AI results; a failed test fails the lane
test_devices:        # each entry = one device run per test case
  - { model: "a54x", version: "34", locale: "en", orientation: "portrait" }
notifications:
  email:
    enabled: true
    notify_on_success: true
    notify_on_failure: true
    recipients: "${TEST_ALERT_EMAIL_RECIPIENTS}"
  • The file contains a commented catalog of Firebase devices. Uncomment entries to enable them.
  • You can override settings per environment under android.environments.<env>.app_testing.
Precedence: environment app_testing → testing.yml → built-in default (Pixel 8 / API 34).
