    If this test is failing unexpectedly, the VCR cassette may be to blame.
    This can happen when changing `describe`/`context` labels on some specs;
    see commit message 1ebddff95 for details.

    Check `git status` to see if a new VCR cassette has been generated.
    If so, rename the old cassette to replace the new one and try again.
