Accessibility validation with RAVEN

Testing is, for most, a necessary evil in the software life cycle. One very important form of testing is the evaluation of software products according to mandated criteria or guidelines such as those that specify level of accessibility. Such evaluations can be quite tedious, especially if they must be done manually and applied consistently to each and every component of an application. The use of assistive technologies like screen readers to demonstrate the compliance of a software product to a set of regulations is time-consuming, error-prone, and expensive. Validation tools that can perform such evaluations are becoming more popular as integrated development environments become more sophisticated but, in the area of accessibility validation, they are sorely lacking if not nonexistent. This paper introduces the IBM Rule-based Accessibility Validation Environment, an Eclipse-based tool for inspecting and validating Java rich-client GUIs for accessibility using non-invasive, semi- to fully-automatic, rule-based validation and inspection.
