Original worked exampleAccessibility Testing

Another example

A specialist tests checkout with axe, a keyboard, page zoom, and a screen reader. Each problem links to a rule and steps others can repeat. One automatic scan cannot prove full accessibility.

Main parts

  1. 01standards checks
  2. 02keyboard and AT path
  3. 03reproducible finding

Use it when

Use this term throughout design and development when checking standards, task completion, and assistive technology.

Do not use it when

Do not treat a passed scanner as proof that disabled people can finish the task.

Name used in code

automated rules + manual checks + user tasks

Before you ship

Check the environment and prepared test data (fixture). Define a result you can observe, failure and edge cases, isolation, stable inputs, useful error details, and cleanup. Set a time budget, owner, and flaky-test rule.

Outcome: Use Accessibility Testing to gather repeatable evidence about this behavior or quality risk. User context: A specialist tests checkout with axe, a keyboard, page zoom, and a screen reader. Each problem links to a rule and steps others can repeat. One automatic scan cannot prove full accessibility. Validation approach: Accessibility Testing. Why it fits: Use this term throughout design and development when checking standards, task completion, and assistive technology. Do not use it when: Do not treat a passed scanner as proof that disabled people can finish the task. Test requirements: Name the system and test environment. Define prepared test data, other inputs, and the result you can observe. Include failure and edge cases, allowed error, isolation, and cleanup. Test operations: Make failures easy to diagnose. Control random or changing inputs. Name an owner. Keep the test fast and simple enough for its release gate. Acceptance criteria: The test fails for the known bug and passes after the fix. It repeats in the target environment, gives useful evidence, and does not expose or change unrelated data. Evidence and limits (evidence boundary): It is official for that source. Other platforms or teams may use the term in another way. Unknowns to confirm: Release gate, environment, prepared test data, allowed error, time budget, owner, and flaky-test rule.
