SVG Accessibility/Testing/Test Assertions with Tables for ATTA 2

Testing

The following are testable statements for SVG accessibility. id of element to test is test (id="test"). Expected results are always for the element with the id="test".

Definition of BLANK is here https://www.w3.org/WAI/PF/wiki/ARIA/Tests/Testable_Statements#Definition_of_.27BLANK.27.

NAOC (or NOAC) = No accessible object created in the accessibility tree

Language dependent tests are here Language Test Assertions

As of March 30, 2016 101 tests are captured

• 17 tests for name
• 16 tests for description
• 19 tests for role (in accessibility tree)
• 8 tests for role = presentation (not in accessibility tree)
• 11 tests for role = none (not in accessibility tree)
• 30 tests for not in accessibility tree (default mappings...)
