How to learn accessibility testing in six milestones — semantics and the accessibility tree, a 14-issue manual audit with an answer key, automated axe checks, keyboard and form tests in code, screen readers and zoom, and a real audit with a report.
Tasks with expected results for each of the six accessibility testing milestones — the accessibility tree, a 14-issue manual audit with an answer key, axe scans, keyboard and form tests in code, screen readers and zoom, and a real audit report.
