How to Use This Checklist
- Review each of the best practice and “check off” all the best practices that DO NOT APPLY to the mobile application under testing, using the N/A column.
For example, if a mobile application does not have any multi-media content, then Best Practice 1.9 – 1.13 can be marked with “N/A” and the Visual Review can be skipped.□ Other items marked as “Skip” can be ignored for the corresponding testing. - Perform Visual Review by checking all items listed in the visual review column.
- Test using Screen Readers.
