The new Test widget enables running all tests with one click, includes coverage reports, and provides debugging panels. This approach fills the gap between unit tests and E2E tests, allowing developers to test thousands of UI states with minimal maintenance while leveraging existing stories as test cases. ## Full article daily.dev links to this article rather than hosting it.

It's nice to see them shipped in Storybook itself, but it also means we'll soon have a lot of technical debt to deal with (migrate from custom tools to built-in ones) 馃槶 ## Similar posts on daily.dev - [Don鈥檛 just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) 路 CNCF 路 0 upvotes 路 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) 路 CNCF 路 1 upvotes 路 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) 路 CNCF 路 0 upvotes 路 0 comments - [CNCF Unveils Schedule for KubeCon \+ CloudNativeCon Europe 2026](https://daily.dev/posts/cncf-unveils-schedule-for-kubecon-cloudnativecon-europe-2026-ikhcoa5cb) 路 CNCF 路 2 upvotes 路 0 comments - [CNCF Debuts KubeCon \+ CloudNativeCon Japan 2026 Schedule](https://daily.dev/posts/cncf-debuts-kubecon-cloudnativecon-japan-2026-schedule-xp5pyudub) 路 CNCF 路 1 upvotes 路 0 comments --- Tags: [#testing](https://daily.dev/tags/testing), [#frontend](https://daily.dev/tags/frontend), [#accessibility](https://daily.dev/tags/accessibility), [#storybook](https://daily.dev/tags/storybook), [#vitest](https://daily.dev/tags/vitest) [View this post on daily.dev](https://daily.dev/posts/component-test-with-storybook-and-vitest-bxyqscwth)
