Checklist: 20 Essential Test Cases for Mobile Apps in 2025

Q: Should I use the same checklist for Android and iOS?

Yes, mostly the same checklist applies, but you should customize for platform-specific differences such as UI layouts, permission flows, and gestures.

Q: How often should these test cases be run?

These test cases should be run after every major release. Where possible, automate them to save time and improve consistency.

Q: Can this checklist be used for hybrid apps like Flutter or React Native?

Yes. The checklist applies to native, hybrid, and cross-platform apps with only minor adjustments needed in some areas.

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.
