Why Android teams choose Espresso
Espresso is part of the Android testing toolkit and runs in the same process as your app. It knows when the UI thread is busy and waits, which removes most timing problems. Tests are written in Kotlin or Java, so Android developers can own them.
Combined with Compose testing APIs, Hilt test modules and managed devices in Gradle, Espresso gives Android teams fast UI tests they can run on every pull request.
What we build
Test architecture
Robot or screen-object patterns that keep tests short and readable.
Idling resources
Synchronisation for network, databases and background work.
Dependency injection
Hilt or Koin test modules to swap in fakes and mock servers.
Compose and Views
Coverage for both, including mixed screens during migrations.
Intents and permissions
Espresso-Intents, deep links and runtime permission handling.
Device farms
Gradle Managed Devices and Firebase Test Lab with sharded runs.
How we keep suites stable
- Hermetic tests: Mock web servers and fake repositories, so tests never depend on staging.
- Test orchestrator: Each test runs in its own instrumentation to avoid shared state.
- Animations off in CI: Device settings that remove a common source of flakiness.
- Screenshot tests where useful: Visual checks for complex layouts alongside behaviour tests.
- Developer ownership: Tests live next to the feature code and run on every pull request.
Espresso or Appium?
- Choose Espresso: For native Android apps where speed and developer ownership matter most.
- Choose Appium: When one suite must cover iOS and Android, or QA writes tests outside the app code.
- Use both: Espresso for fast PR checks, Appium for cross-platform end-to-end journeys.
- Pair with XCUITest: The native equivalent for iOS teams who want the same benefits.
Where it fits
Espresso engagements usually sit alongside API testing for your backend and, for cross-platform products, an Appium or Detox suite that covers both platforms end to end. See our QA automation, API testing and performance testing services.
