Accessibility Testing Naisargi Shah

What is Accessibility Testing?  It is a subset of usability testing.  Software is tested to decide the accessibility of the software for those with disabilities.

Who to consider ?  Software developer/tester should keep in mind the people with:  Blindness or low vision  Deafness or hearing loss  Limited movement  Photosensitivity  Speech disabilities  Reading disorders  Neurological disabilities

Standards and Guidelines  WCAG (Web Content Accessibility Guidelines)  WCAG 2.0  Disability Discrimination Act (mostly in UK, Australia)  Americans with Disabilities Act (ADA)

WCAG

WCAG 2.0  Collection of guidelines, which states the accessibility standards for web software.  Has 4 principles which consists of 12 guidelines.  Within the guidelines, there are success criteria with 3 different levels: A, AA, AAA.

Principle 1: PerceivablePrinciple 2: Operable  Guideline 1: Text Alternative  Guideline 2: Time-based media  Guideline 3: Adaptable  Guideline 4: Distinguishable  Guideline 5: Keyboard Accessible  Guideline 6: Enough Time  Guideline 7: Seizures  Guideline 8: Navigable

Principle 3: UnderstandablePrinciple 4: Robust  Guideline 9: Readable  Guideline 10: Predictable  Guideline 11: Input Assistance  Guideline 12: Compatible

Tools for Testing  Accessibility Color Wheel: helps make the choice of color pair to use for foreground and background in the software.  Achecker: checks HTML pages using WCAG to check for its accessibility.

Conclusion  Consider people with disabilities while testing.  Entry criteria: look at different types of disabilities.  Exit criteria: software should be stated as accessible.  Every user should get equivalent access.
