• Dramatically faster to a first working test than Appium — minutes versus days.
• Built-in tolerance for asynchronous UI removes most flake without explicit waits.
• Readable YAML that a product manager can follow.

• 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.

• YAML limits complex conditional logic and data-driven scenarios.
• Younger project with a smaller ecosystem than Appium.
• Fewer integrations with enterprise device clouds.

• Android only.
• Testing across app boundaries requires UiAutomator alongside it.
• Compose testing uses a related but separate API to learn.
