UI Accessibility Checker (or AccChecker) enables testers without prior experience to easily discover accessibility problems with Microsoft Active Accessibility (MSAA) and other User Interfaces (UI) implementations. AccChecker was born from the realization that existing MSAA tools, such as Inspect or AccExplorer, provided in-depth details on the implementation, but no information whether that implementation is correct or not.
AccChecker comes in three modes – a Graphical User Interface (GUI) tool for the initial investigations of UIs, a set of simple APIs for easily creating automatic test cases, and a command-line tool for batch processing. Using the GUI tool, a tester can easily scan a UI and review the list of errors and warnings. Then, using the per-issue documentation, the tester can determine why each particular issue has occurred, what the implications may be on a users with disabilities, and how to fix the issue. Once all issues have been fixed, the tester can use the APIs to create regression tests. Finally, the APIs cannot be used for any reason, the tester can use the command-line mode of the tool to create tests in a batch file.
