Checklist: 20 Essential Test Cases for Mobile Apps
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.
Mobile App Test Case Categories
To ensure complete test coverage, this checklist includes test cases across:
- Functional Testing
- UI/UX Testing
- Performance Testing
- Compatibility Testing
- Security Testing

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.
