13.6Interview Talking Point

"I approach visual and accessibility testing as complementary disciplines. For visual regression, I use a combination of Playwright's built-in screenshot comparison for speed and a tool like Percy or Chromatic for cross-browser coverage with AI-powered diff triage that filters out rendering noise and flags only meaningful changes. For accessibility, I run axe-core against every page on every PR as a minimum -- it catches 30-40% of WCAG 2.1 AA issues automatically. But I go beyond rule-based scanning by using AI agents that can evaluate whether alt text is actually descriptive, whether error messages guide the user, and whether the reading flow is logical -- things axe-core fundamentally cannot assess. I also test keyboard navigation end-to-end: our checkout flow must be completable without a mouse, with visible focus indicators and proper focus trapping in modals. With the European Accessibility Act now in force and US ADA lawsuits exceeding 4,000 per year, accessibility is not a nice-to-have -- it is a legal and business requirement that I build into the CI pipeline from day one."
