UX Bug

UX bugs are subtle because the application technically works. The data saves, the page loads, the feature produces correct output. But the user experience is poor: a confusing layout, unclear labels, missing feedback after an action, a workflow that requires too many steps, or behavior that contradicts user expectations.

AI-generated interfaces frequently contain UX bugs because AI tools optimize for functional correctness rather than user experience design. A form might work correctly but provide no feedback after submission, leaving users wondering if anything happened. A navigation structure might be technically functional but organize information in a way that does not match how users think about the content.

UX bugs are nearly impossible to catch with automated testing because they require human judgment about what feels right. They are one of the strongest arguments for human QA testing. A DidItWork tester experiences the application as a real user would and can identify moments of confusion or frustration that no automated tool would flag.
