- Automatic UI-thread synchronisation makes tests both fast and reliable.
- First-party Google support, updated alongside Android itself.
- Runs on emulators in CI cheaply, including Firebase Test Lab.
Limitations
- Smaller device catalogue than BrowserStack or Sauce Labs.
- Generated Appium scripts still need substantial cleanup.
- Mobile only.
- Android only.
- Testing across app boundaries requires UiAutomator alongside it.
- Compose testing uses a related but separate API to learn.
