Storybook test runner

Component story test runner

FreeCode review, testing & securitystorybook.js.org

What it is

Turns every Storybook story into an executable test, powered by Jest and Playwright. It renders each story in a real browser and fails on render errors or thrown exceptions, then executes any play function as an interaction test. Runs headless in CI with sharding and worker controls.

Why it earns a slot

Free smoke-test coverage for every component an AI generated. If a story throws on render because of a missing required prop or a bad default, CI fails before the page does in production.

Know before you commit

It needs a running or pre-built Storybook in CI, which adds a build step and meaningful pipeline time on large component libraries.
