My practical accessibility smoke test before release
A ten-minute accessibility pass any QA can run before release — keyboard, focus, contrast, and the obvious screen-reader checks.
Series
Practical accessibility checks any tester can run before release — and where the tooling stops. You don't need to be a specialist to catch the obvious accessibility failures. This series covers the keyboard-first smoke test, what automated scans like axe catch and miss, and why a Lighthouse score isn't a test.
// overview
Accessibility gets framed as a specialist discipline you need certification to attempt — which is exactly how it ends up tested by nobody. This series makes it practical for ordinary QA: the checks you can run before release with no tooling and no expertise, and a clear-eyed view of where the automated scanners stop.
The arc starts with the highest-value habit — driving the whole flow from the keyboard — widens to a full release smoke test, and then draws the line: what tools like axe catch, what they can't see, and why a Lighthouse score isn't an accessibility test.
You won't come out a specialist. You will come out able to stop the obvious, embarrassing accessibility failures from shipping every sprint.

Tab through the page. That single habit catches more accessibility bugs than most automated scans.
Catch the blatant screen-reader failures in fifteen minutes with the reader already on your machine — meaningful names, sensible images, labelled fields, announced changes.
Forms break accessibility hardest — labels, required state, announced errors, focus management, and keyboard-operable custom widgets. The form-specific pass.
axe-core is the engine behind most accessibility testing in 2026 — and it's surprisingly approachable. Here's a practical walkthrough of integrating axe with Playwright, what it catches, and what it misses.
A 100 Lighthouse accessibility score doesn't mean your site is accessible. The score is a smoke alarm — useful, but not a test. Here's what it actually measures, and what you still need to check manually.
Focus order is the route a keyboard user takes through your page. When it's wrong the page looks perfect and becomes unusable — and scans don't catch it.
