A Practical Guide to Manual Accessibility Test Scripts
Written step-by-step checks that testers follow to verify accessibility beyond automated tools.
Where most projects go wrong
The usual mistakes:
- Relying only on automated scans
- Ad hoc testing with no record
- Scripts written once and abandoned
- Testing only the homepage
What good looks like instead
- Write scripts for key user journeys
- Include keyboard-only and screen reader passes
- Record results consistently
- Run scripts before major releases
- Update scripts as the product changes
Why it matters
Automated tools catch only part of the issues, and scripted manual checks make the rest repeatable.
The specs that matter
| Measure | Figure |
|---|---|
| Coverage | automated tools detect a limited share of accessibility issues |
| Keyboard checks | are the fastest high-value manual test |
| Scripts | make results comparable between testers |
| Assistive technology | screen reader checks need defined steps |
Knowing when to hand it over
