Accessibility refers to a quality requirement for web applications. However, current accessibility automatic evaluation tools cannot evaluate dynamic generated content that characterizes Ajax applications and RIAs. In this context, this paper describes an approach for evaluating Accessible Rich Internet Applications (ARIA) requirements, by using acceptance tests. The authors implemented a set of disabled user interaction scenarios as acceptance tests in order to verify keyboard accessibility in RIA and automatically evaluate ARIA conformance in widgets. The inclusion of disabled user interaction scenarios in the evaluation process is necessary to analyse ARIA requirements since dynamic changes are accommodated in the DOM structure. Two evaluation tool prototypes were developed and validated in separate case studies. The results show evidence that the proposed evaluation approach is capable of evaluating ARIA conformance in RIA widgets.
