I've been building describe-me, a Vitest plugin plus a viewer that turns component tests into docs. It records the DOM after every render and interaction of a test and shows the frames as a browsable catalog: each describe is a group, each it a story, each step a frame. No story files, so the docs cannot drift from the component: if they would, the test fails.

Live : a link to a test mounts the component for real, in your project's own Vite, exactly as the test's arrange phase set it up. You click and type in it, and vi.fn() props show their calls.

Foundations : it reads the design system your tests load (CSS custom properties, Tailwind 4, shadcn/ui, Material UI, or a theme module) and shows the tokens, light and dark, with WCAG contrast of color pairs.

Works in browser mode and in jsdom, with Testing Library and user-event. React 18 and 19, Vitest 4 and 5.…
