Test Suite — ITEM-17 / ITEM-15
Broken Links Cluster
Tests same-domain broken link cluster annotation (ITEM-17 / VA-014) and cross-reference between broken links and co-located accessibility violations (ITEM-15 / VA-007). This page has 4 broken links to the same non-existent domain, plus a missing image alt.
Same-domain broken links (cluster)
BROKEN — 4 links to nonexistent-cluster-domain-vesper-test.com. All will fail the link check. Expected report annotation: "Domain pattern detected: nonexistent-cluster-domain-vesper-test.com (4 broken links) — may indicate a domain-level issue".
All four links go to different paths on the same non-existent domain. The cluster annotation should appear in the broken links report.
Accessibility violation on same page (cross-reference)
FAIL — image-alt (critical). A missing alt attribute on an image on this page. Expected cross-reference: in the broken links report, the "Found On" column for the four broken links above should show "(+1 a11y)" noting this page has an accessibility violation.
Image above has no alt attribute — intentional violation for cross-reference QA.
Clean external links (no broken)
PASS — these external links should resolve successfully and not contribute to the cluster count.
