Rapports d’anomalies
Exclude URLs from this report
Hide findings on pages you are not responsible for — a section another team owns, or legacy pages out of contract. One pattern per line: a plain substring that matches anywhere in the URL (/medicare/, .aspx) or a slash-wrapped /regex/ (/medicare|medicaid/i); # comments are ignored. A finding is hidden when every affected page matches; for findings with more than 25 pages this is judged by the listed sample. This only changes what this report shows in your browser — every page is still scanned, and your list is saved on this device.
Automated testing does not establish full WCAG conformance. Findings in the verification lane require manual testing before they are treated as confirmed failures.
The 50 highest-priority findings are shown in full; 28 more lower-priority finding(s) are summarised at the end of the page, and every finding is in the CSV/JSON downloads.
5 constat(s) marqué(s) « doublon possible » — Alfa et axe-core ont tous deux signalé le même critère WCAG sur des pages qui se recoupent. S'ils ciblent le même élément, le rapport axe-core fait autorité. Filtrez le CSV par possible_duplicate_of pour les voir. Deux moteurs signalant le même obstacle réduisent le risque de faux positif.
