Manual testing

Automated testing is just the beginning of the accessibility process. It actually catches only about 25% of accessibility errors. Many other elements require a human judgment call, such as deciding whether a feature makes sense in context, or is consistent with other pages on your site.

It is therefore essential to combine automated testing with "real world" manual testing. UCLA developed Quick Tests for Accessibility (pdf) to provide a structured approach to manual testing. These tests are intended to be fast, repeatable, verifiable, applicable to large amounts of content, and to accompany automated testing. They define and provide quick testing approaches for eight common scenarios: ensuring consistent navigation, checking color contrast, enlarging text without breaking layout, detecting text embedded in graphics, and providing logical structure, visible focus, captions, and image accessibility.
