Accessibility for developers

Building accessible digital services depends in part on a test-driven approach to help make them as robust and operable as possible for as many users as possible.

This part of the manual provides guidance on:

• What do I need to test?
• When do I need to test?
• How do I run tests?
• How to write accessible code
• Using ARIA correctly
• How to test with a keyboard
• How to test with screen readers
• Automated testing tools
• Manual testing and guided manual testing tools
• Understanding Authoring Tool Accessibility Guidelines (ATAG)
