Rerun builds in one click

Visual tests require UI to render consistently to prevent false positives. But in fast-moving teams, discerning whether a snapshot change is real or caused by inconsistencies in your app code can be tough.

To help you debug unexpected visual changes, I’m excited to introduce Chromatic’s rerun build button. It takes new snapshots of denied and unreviewed changes, all without needing you to go through the entire CI process again.

How to rerun a build

Click “rerun” on the build page to kick off a new build using the exact same settings and configuration as your original build. It only retakes snapshots of denied and unreviewed changes to speed up debugging.

Inconsistent snapshot detection

Examining the changes between the original build and rerun build helps you discern inconsistent snapshots. If the set of changes is identical between builds, you introduced bonafide UI changes that need verification. If the set of changes is different between builds, there are inconsistent snapshots that need to be debugged.

Chromatic automatically detects both scenarios and calls out potential rendering inconsistencies on the build page.

Rerunning builds is now available for the latest builds on every branch. Try it out and let us know what you think. Learn more on the docs.

Visual Tests addon sneak peek

We’re working on a way to run visual tests on-demand from Storybook. This helps you find issues during development without needing to wait on other CI jobs to finish.
