Article Summary
Shubhnik Singh Mann from Razorpay reveals why most mobile teams are testing wrong. Their approach eliminated P0 production issues entirely.
Razorpay's mobile team shares their battle-tested strategy for shipping React Native features without regression. They break down the difference between tests that catch bugs and tests that just waste time, using real examples from their Payment Link feature.
Key Takeaways
- Shallow rendering creates false positives by testing components without their children
- Testing implementation details breaks refactors even when user experience stays identical
- Integration tests with full component trees catch bugs unit tests miss
- Simulate user interactions with fireEvent instead of calling component methods directly
- Reserve snapshot tests for reusable UI components, not stateful logic
