Testing
Manual Testing
Keyboard-only navigation, screen reader testing (NVDA/JAWS/VoiceOver), zoom to 400%, check focus order, verify ARIA states. Catches the 60% that automated tools miss.
In plain terms
Checking by hand — using only a keyboard, a screen reader, and zoom — to catch the majority of problems that tools miss.
Why this matters
The majority of real barriers — broken keyboard flows, illogical focus order, meaningless labels — can only be found by a person. Skip manual testing and you ship the very problems that affect users most.
