@vitest.devWith this change, we hope to take the agency back to us and away from an uncontrollable sweep of agents.
@vitest.devThe amount of new pull requests per day is now too high to manage it with the amount of care and thought that we believe Vitest deserves.
@vitest.devWe are updating our AI Policy to reduce maintenance stress. All pull requests are now automatically closed, unless they are created by maintainers or users from an approved list of contributors. The PR is not lost. If the team decides the change is worth pursuing, we will reopen it.

@ariperkkio.devReposted by @vitest.devThis Thursday we'll be discussing about Visual Regression Testing using @vitest.dev and @chromatic.com. Join me and @kylegach.com to hear how you can get VRT that's stable across your whole team, not just on your local machine. 📸
@chromatic.comReposted by @vitest.dev@vitest.dev already renders your components in a real browser. Now you can visually test them there, with no test code changes.
🎙️ @ariperkkio.dev, the Vitest core maintainer who built our new plugin, is doing a live walkthru with @kylegach.com to show you how.

Time to update 👀
@43081j.comReposted by @vitest.devBig win! Migrated the whole @netlify.com build repo to @vitest.dev 🎉🎉
Also made heavy use of my snapshot diff tool since ava has binary snapshots (accounting for most of the 40k+ PR 😅)
@alexanderkaran.bsky.socialReposted by @vitest.devI’m gonna be honest my life is so much happier with Vitest in it.
@chromatic.comReposted by @vitest.devChromatic for @vitest.dev Browser Mode is live. 🧪📸
Browser Mode runs your component tests in a real browser. Now Chromatic checks how those components look by capturing the rendered UI.
No new screenshot assertions. No second suite to maintain. 🧵 (1/4)
