See Accessible text requirements for more information on contrast ratio and exceptions. The exceptions include inactive UI elements, and logos or decorative text that doesn’t convey any information and can be rearranged without changing the meaning. Use color contrast tools to verify that the visible text contrast ratio is acceptable. Verify the contrast ratio of visible text Finally, make sure that you can invoke all interactive UI elements with the keyboard once those elements have focus, typically by using the Enter or Spacebar key. For example, you should be able to navigate lists of items using keyboard keys. For composite UI elements, verify that you can navigate among the parts of elements by using the arrow keys. You should be able to cycle through all interactive UI elements by using Tab key. Test keyboard accessibility navigation by using the Tab key. The best way to test your keyboard accessibility is to unplug your mouse or use the On-Screen Keyboard if you are using a tablet device. You can run some of the tools while developing and using an emulator, but most of these tools can't expose the UI Automation tree within the emulator. Most accessibility testing tools mentioned in the documentation run on a PC, not on a phone. Changes in the UI can occur when the focus changes, or when a UI element is invoked, selected, or has a state or property change. Accessible Event WatcherĪccessible Event Watcher (AccEvent) tests whether an app's UI elements fire proper UI Automation and Microsoft Active Accessibility events when UI changes occur.

To run the UI mode tool, open the AccChecker directory in the Windows SDK bin directory, run acccheckui.exe, and click the Help menu. You can run AccChecker in UI or command line mode. When your UI is complete and functional, use AccChecker to test different scenarios, verify the correctness of runtime accessibility information, and discover runtime issues. UI Accessibility Checker (AccChecker) helps you discover accessibility problems at run time. The following image shows the Inspect tool querying the UI Automation properties of the Edit menu element in Notepad. In other cases the attributes come from specific values that you have set in your XAML markup, as AutomationProperties attached properties. In some cases the attributes come from the UI Automation support that is already implemented for default XAML controls.

Use Inspect as you develop the UI to verify how accessibility attributes are exposed in UI Automation. You can view Microsoft UI Automation properties and control patterns and test the navigational structure of the automation elements in the UI Automation tree. Inspect enables you to select any UI element and view its accessibility data. It's particularly intended for testing Narrator accessibility scenarios with your app. The AccScope tool enables developers and testers to evaluate the accessibility of their app during the app's development and design, potentially in earlier prototype phases, rather than in the late testing phases of an app's development cycle.
