Maestro: Reliable E2E testing made easy

End-to-end tests are often brittle, slow, and painful to maintain. But what if you could write E2E tests as easily as user stories, run them locally and in CI, and skip the flaky UI tests that break on every layout change? In this talk, I’ll walk you through how Maestro, an open-source mobile UI testing framework, is reshaping the way we think about mobile E2E testing. We’ll explore how to set it up in under 5 minutes, write human-readable flows, integrate with CI, and gain confidence in your critical user journeys - from login to money transfer. Whether you’re a test automation skeptic or looking for simpler tools, this session will give you a practical, production-ready approach to mobile E2E testing.
