• Fastest and most reliable option on iOS, with no third-party layer to break.
• Native accessibility-hierarchy access and built-in test recording.
• Guaranteed to keep working with each iOS release.

• 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.

• iOS and macOS only, and Swift only.
• Requires macOS CI runners, which are expensive to rent or own.
• Element queries are less expressive than modern web locators.

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

iOS teams that ship native and want first-party reliability.

Android teams that want the fastest, most reliable native UI tests.
