    Accessibility Snapshots, by Tikitu de Jager (English)

    Posted on June 26, 2021


    In this talk Tikitu de Jager, a mobile lead at Minddistrict, will show you a test utility they use to refactor view layers with confidence that they haven’t broken VoiceOver support, even in complex custom layouts. The tool itself is quite simple but it touches on more general accessibility best practises and on snapshot-testing techniques that go beyond pixel-perfection.
