Mobile Testing Strategy

Instructions

Mobile testing has a sharper pyramid than web or backend because simulators are imperfect, devices are expensive, and flakiness kills developer trust. A good strategy maximizes signal per minute of CI.

1. The Pyramid

              E2E on device
             /              \
         UI / widget tests
        /                    \
   Integration (repo + fake net)
  /                                 \
Unit tests (domain, reducers, utils)  <-- the broad base

Rough ratios for a healthy app: 70% unit, 20% integration, 7% UI, 3% E2E.
