Automation is a fast first pass

Automated tools are excellent at deterministic checks such as missing names, invalid relationships, and some contrast failures. They cannot decide whether alternative text is useful, focus order makes sense, or a workflow is understandable.

A credible audit records scope, browser, assistive technology, viewport, tasks, and known limits. Retest fixes instead of treating the report as the end.

Write findings people can reproduce

Include the barrier, affected users, steps, actual result, expected result, standard reference, severity, and a focused recommendation. Separate confirmed failures from risks that need more testing.

Prioritize blockers in core tasks, then widespread and severe barriers. Cosmetic rule violations with little impact should not outrank an unlabeled payment control.

Your studio task

Make — Create an audit report with automated results and four manual test passes.

  1. Define three representative tasks and the test environment.
  2. Run automation, keyboard, zoom, and one screen-reader pass.
  3. Write each confirmed finding with reproduction and impact.
  4. Fix the highest-severity issue and retest the original task.
Definition of done

The report separates confirmed barriers, tool warnings, false positives, and untested risk.

Knowledge check

Which problem is an automated scanner least able to judge?
  1. A form control has no programmatic label
  2. Alternative text accurately communicates the image’s purpose
  3. An ID is duplicated
Reveal answer (B)

The usefulness of alternative text depends on content and context, which requires human judgment.

A reproducible finding includes…
  1. Steps to reproduce and the impact on users
  2. Only a screenshot
  3. Only the automated tool name
Reveal answer (A)

Reproduction and impact let others verify severity and prioritization.
