jest-image-snapshot-diff-reporter

jest-image-snapshot-diff-reporter

Reports diff images for failing image snapshot tests which are using jest-image-snapshot. It helps to debug tests that are failing on CI where you can not access diff images directly.

NOTE: Currently only prints them on console in base64 if CI env variable set

Setup

yarn add --dev jest-image-snapshot-diff-reporter`

"jest": {
  ...
  "reporters": ["default", "jest-image-snapshot-diff-reporter", ...]
  ...
}

Roadmap

• Respect jest-image-snapshot configuration such as customDiffDir and customSnapshotsDir
• Support custom reporter function via config, that runs on each diff image. (so that they can be sent to somewhere else such as S3)
