In Library > Quarantined, you can see each test’s issue rate. Fix the flake, remove quarantine, and put the test back to work. While quarantined, it won’t catch regressions. (4/5)

The test doesn’t disappear. Quarantined diffs show up in the build’s Unstable group, alongside tests caught by the automatic flake filter. Expand the group to inspect them. (3/5)
ALT Unstable group of quarantined diffs in Chromatic
Chromatic keeps capturing snapshots for quarantined tests, but ignores their diffs across builds, branches, and users. So the same flaky diff won’t keep showing up for review. (2/5)

📣 New in Chromatic: Quarantine for flaky tests
You can now quarantine the flaky diffs that slip past Chromatic’s automatic filter. Quarantine the test from its build or test page to get your PR moving. 🧵⤵️ (1/5)

Run your tests as usual. Chromatic then:
✔️ Compares snapshots across stable cloud browsers
✔️ Runs every browser and viewport in parallel
✔️ Surfaces visual changes in your PR for team review
✔️ Stores the full rendered UI behind every diff

Vitest core maintainer Ari Perkkiö built the plugin around Browser Mode tests.
As tests run, Chromatic captures a web archive of each result: the HTML, CSS, JS & assets behind the UI. When something is off, open that state in a browser instead of debugging a screenshot. (2/4)

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)
