When to test with AT
Test with assistive technology as part of:
- Development - An accessible front-end development approach includes checking code with assistive technology during development.
- UX review - Designers are responsible for reviewing the experience for all users, not just the visual UX. Reviewing the HTML could be one step in the review process. This should never replace reviewing the user experience with a screen reader and other assistive technologies. When a component has been developed and is ready for UX review, designers can review and sign off the screen reader UX during an accessibility swarm.
- Accessibility swarms - Assistive technology testing forms part of an accessibility swarm, along with other accessibliity checks. As a miminum, test with all supported assistive technology during an accessibility swarm to be considered acceptable for a live release.
