# BEGIN test cases
#
# Feel free to add as needed. Syntax is:
#    <exit status>  <sha of commit>  <branch>=<sha of merge base>  # comments
#
# Where:
#    exit status       is the expected exit status of the script
#    sha of merge base is the SHA of the branch point of the commit
#    sha of commit     is the SHA of a real commit in the podman repo
#
# We need the actual sha of the merge base because once a branch is
# merged 'git merge-base' (used in our test script) becomes useless.
#
#
# FIXME: as of 2021-01-07 we don't have "no tests needed" in our git
#        commit history, but once we do, please add a new '0' test here.
