A great mobile app doesn’t just look good — it must perform consistently across devices, networks, and user scenarios.
Even a well-designed app can fail if not thoroughly tested. That’s why QA teams rely on structured test cases to validate UI, logic, security, and performance.
In this guide, you’ll find a checklist of 20 essential mobile test cases, grouped by testing type, applicable to both Android and iOS platforms.

FAQs
Q1: Should I use the same checklist for Android and iOS?
A: Mostly yes — but customize for platform-specific behaviors (UI layouts, permission flows, gestures).
Q2: How often should these test cases be run?
A: After every major release. Automate wherever possible.
Q3: Can this checklist be used for hybrid apps like Flutter or React Native?
A: Yes. It applies broadly to native, hybrid, and cross-platform apps.
