axe-core Explained: The Industry-Standard Accessibility Testing Engine
Findings and manual review
axe-core is the open-source rules engine used by AllyProof alongside HTML_CodeSniffer and separate APCA advisory checks. Deque aims to avoid false positives, while acknowledging that software bugs can occur. This is a design policy, not a guarantee that every result from AllyProof's combined pipeline is correct.
| Result | Interpretation |
|---|---|
violations | A configured rule reported a failure. |
incomplete | Manual review is needed. |
passes | The specific rule check passed in the tested context. |
inapplicable | No applicable elements were found. |
Inspect the affected element, rule guidance, and page state when reviewing a finding. A scan covers the pages, states, and rules executed; a passing check does not establish conformance with an entire success criterion or website.
AllyProof combines inherited WCAG version tags rather than requesting only the latest additions. Best-practice and advisory results remain distinct from scored findings. Plan manual evaluation alongside automated scanning.
