Annotated screenshots
Mark the differing regions so the fix is obvious.
How to build it
- Load the screenshot and the design frame and find the regions that differ.
- Draw a box or outline around each differing region on the screenshot.
- Attach the annotated image to the pull request or the failing test.
Signals in a repository
- A script that writes an annotated diff image as a CI artifact.
- Pillow or OpenCV in the test tooling dependencies.
In practice
No scanned repository runs a tool for this check. The steps above are the only guidance.
