Accessibility Regression Workflow

Add automated accessibility checks per pull request with a curated rule set and manual checks for the rest.

Overview

Prevent accessibility regressions through repeatable automated and manual checks.

This workflow is reusable across teams and environments; adapt the commands to your tooling while keeping the sequence and checkpoints intact.

Environment and prerequisites

• An accessibility scanner in CI
• A curated rule set
• Manual test guidance

Procedure

1. Run automated checks on changed pages

Scan pages affected by the change for high-signal accessibility violations.

Expected state: Automated violations are caught before merge.

2. Focus on high-signal rules

Gate on rules that reliably indicate real problems, warn on the rest.

Expected state: The gate is trusted, not ignored.

3. Keep a manual checklist

Cover keyboard and screen-reader checks that automation cannot verify.

Expected state: Semantic and interaction issues are still tested.

4. Triage findings by severity

Fix blockers immediately and schedule lower-severity items.

Expected state: Accessibility debt is managed.

Verification

Confirm a change introducing a high-signal violation fails CI and the manual checklist is completed for critical journeys.

Decision points

Gate on all rules or a curated set?

• Curated high-signal rules
• All rules

Recommendation: Gate on high-signal rules; noisy gates get disabled.

Rely on automation alone?

• Automate what is verifiable plus manual checks
• Automation only

Recommendation: Automation misses semantics; keep manual checks for journeys.

Common failures

• Noisy gates get disabled and ignored.
• Automation-only misses semantic issues.
• No severity triage leaves debt unmanaged.
