Targets

UK GDS Accessibility Tool Audit Test Pages
One per page
defectlab.app/alphagov
This is the set of test pages used by the UK Government Digital Service for its Accessibility Tool Audit, conducted between 2016 and 2018. Every defect has its own dedicated page, so each finding belongs to a single accessibility use case. The entry point is a simple list of the pages, nearly all of them carrying a single defect that can be scanned.

UK GDS Accessibility Tool Audit Test Page
Single page
defectlab.app/alphagov-single
This is the consolidated test page used by the UK Government Digital Service for its Accessibility Tool Audit. Every defect sits on this one page, so all findings can be scanned in a single pass.

WCAG 2.2 A and AA Suite
Static HTML
defectlab.app/wcag22-static
An authored suite of test pages covering every WCAG 2.2 Level A and AA success criterion. Every defect has a correct twin, so a scan measures what a tool wrongly flags as well as what it finds. Each case is marked in the markup, so findings map back to it exactly.
