PDF Accessibility - Test Procedures & Requirements
The Visa Global Accessibility Requirements (VGAR) is a combination of requirements and complimentary test procedures that help teams create and verify accessible PDF documents.
For accessibility testing, the tester simply executes the test cases and determines whether each page in the PDF document being tested passes or fails the test case. When a failure is found, the tester then documents the failure and provides it to the development team for remediation. The development team subsequently references both the identified failure and the corresponding requirement to assist in the remediation effort.
