Our Android testing process

Headspace went from <20% test coverage to 80%+ during a complete app rewrite. Here's how they built a testing strategy that actually works.

The Headspace Android team shares their journey from minimal testing to a robust, multi-layered testing strategy. They detail how they balance speed with confidence using unit tests, integration tests, and E2E tests across 4,600+ test cases.

Key Takeaways

• Unit tests run in under 5 minutes for 4,600+ tests using MockK and Robolectric
• Integration tests with MockWebServer eliminated network flakiness that plagued E2E tests
• Tests categorized as Smoke, Regression, and MAT run at different pipeline stages
• Report Portal integration with Slack automates bug ticketing and simplifies test reporting
• Parallel testing with Flank across multiple devices cuts execution time dramatically

Their approach to handling test flakiness and the custom reporting solution they built might change how you think about mobile CI/CD.
