When you test your accessible applications, follow these recommendations:

• Ensure that you have enabled accessibility. For more information, see Configuring Flex applications for accessibility.
• Test and verify that users can navigate your interactive content effectively by using only the keyboard. This can be an especially challenging requirement, because different screen readers work in different ways when processing input from the keyboard, which means that your content might not receive keystrokes as you intended. Ensure that you test all keyboard shortcuts.
• Ensure that graphic content has alternative representation by checking for tool tips on every image.
• Ensure that your content is resizable or sized to work with screen magnifiers. It should clearly present all material at smaller sizes.
• Ensure that any substantive audio is captioned. To test for content loss, try using your application with your sound muted or wearing headphones that pipe in unrelated music.
• Ensure that you use a clean and simple interface to help screen readers and users with cognitive impairments navigate through your application. Give your application to people who have never seen it before and watch while they try to perform key tasks without any assistance or documentation. If they fail, consider modifying your interface.
• Test your application with a screen reader, or have it tested by users of screen readers.
