What is a key characteristic of the test scripts in a successful accessibility test plan?

In a successful accessibility test plan, key characteristics of the test scripts include being standardized and specific. This is crucial because standardized test scripts help ensure consistency across different testing sessions, enabling multiple testers to evaluate the same criteria in a uniform way. Specificity is also essential, as it allows testers to target particular accessibility guidelines or issues relevant to the content being examined. When test scripts are well-defined, they facilitate clearer communication among team members and stakeholders regarding the accessibility requirements being assessed.

Furthermore, having standardized and specific test scripts enhances the reliability of the testing process. This means that results can be compared across different projects or timeframes, making it easier to identify recurring issues or improvements over time. This structured approach is vital for effectively addressing accessibility challenges and ensuring compliance with established guidelines and standards, such as the Web Content Accessibility Guidelines (WCAG).
