Check a form error message
Check a web form error message for accuracy, placement, accessibility, recovery guidance, privacy, and state preservation.
An error should identify the problem and make the next action clear.
When to use
- Use during form design, content review, accessibility testing, or defect verification.
- Do not expose credentials, account existence, payment details, or sensitive submitted values.
Procedure
- Record field, input state, trigger, expected rule, actual message, device, browser, and assistive technology.
- Confirm the message describes the real problem in plain language without blame or unsupported certainty.
- Check that it appears near the field and in an error summary where the form needs one.
- Verify programmatic association, announcement, focus movement, color-independent indication, and readable contrast.
- Confirm correction guidance, accepted format, limits, and examples are accurate.
- Verify unaffected values remain, sensitive values are handled safely, and retry does not duplicate an action.
- Test empty, malformed, boundary, server, timeout, and corrected submissions.
