1. Developers Testing Their Own Build

When you’re too close to the product, it’s easy to miss critical issues. A fresh pair of eyes—like a dedicated QA team—can uncover bugs and UX flaws you might overlook.

2. Ignoring Real User Behavior

Not everyone uses the app the way it was intended. Users take unexpected paths. Effective testing should simulate real-world usage—not just the “happy path”.

3. No Clear Understanding of App Functionality

If testers don’t fully understand the app’s features, flow, or purpose, they can’t validate whether it’s working correctly. Proper onboarding and documentation are essential.

4. Poor Testing Environment

Bad lighting, reflective surfaces, or limited play space can interfere with tracking—leading to false bug reports. Test in realistic and optimized conditions.

5. Lack of a Testing Plan

 Random testing leads to missed bugs and inconsistent results. A well-structured test plan ensures thorough coverage, repeatability, and accountability.
