Snapshots in CI

With the CI environment variable set, as GitHub Actions, Azure Pipelines, GitLab and most other CI systems do, snapshots are never accepted. A missing verified file fails the test, and SNAPSHOT_ACCEPT=1 is ignored with a note in the failure message:

SNAPSHOT_ACCEPT is ignored because CI is set: snapshots are never accepted in CI.

Getting the received files out of CI

Received files go to your artifacts folder when the build uses one (UseArtifactsOutput; the folder is artifacts/ unless ArtifactsPath says otherwise), so uploading it is enough:

- uses: actions/upload-artifact@v7
  if: failure()
  with:
    name: received-snapshots
    path: artifacts/.snapshots/received/

Download that into the same place locally and snap review picks it up.

Without an artifacts folder they are in each test project's obj/snapshots/received/.

Line endings

Snapshots are compared after normalising line endings, so a Windows checkout with CRLF passes. To keep the working tree consistent too, add this to .gitattributes:

*.verified.* text eol=lf
