description: Verify website changes through visitor journeys, appropriate automated tests and browser checks. Use when testing a website, investigating a failure or preparing a release.
---

Start from the brief and observable acceptance criteria. Inspect existing test and build commands; do not assume that a script exists. Choose checks based on the changed behaviour and the cost of failure.

Exercise the main visitor journey and affected links, navigation and forms. Include invalid input and relevant error states. For a contact form, verify actual delivery in the agreed test destination before reporting that it works. For an email link, explain that it opens the visitor's configured email app and does not send a message automatically.

Check narrow and wide screens in a browser. Include keyboard navigation, visible focus, accessible names, zoom and horizontal overflow. Automated accessibility results complement these manual checks and do not establish complete accessibility conformance.

Add automated tests for important behaviour or demonstrated regressions. Test observable outcomes and meaningful failure cases; avoid tests that merely repeat the implementation or match incidental wording. Use disposable test data and local fixtures. Never send real messages, charge payments or alter production data without the user's authorization.

Reproduce a failure, fix its cause and rerun affected checks. Report commands run, results, browser checks performed and anything not checked. A successful build shows that the site can be generated; verify visitor behaviour separately. Never report a check as passed when it was skipped or unavailable.
