## AI overview

The article describes a baseline-driven approach to accessibility reporting. It extends an in-house test automation framework so new test runs can be compared with a snapshot of known issues on the main branch, helping teams distinguish regressions from existing technical debt and track changes more clearly.

## Source excerpt

The output of most automated accessibility tests is a long list of violations. This format, while comprehensive, makes it difficult to distinguish new issues introduced in a feature branch from ...
