# BEGIN user-customizable section
#
# These are the hand-maintained exceptions. This is what you want to edit
# or update as needed.
#
# There are three directives you can use below:
#
# errmsg "old-message" "new-message" "test name" ["test name"...]
#
# This replaced "old-message" with "new-message" in @test "test name".
# It is used when a podman error message differs from buildah's.
#
# [skip | skip_if_remote] "reason" "test name" ["test name"...]
#
# This adds a 'skip' statement as the first line of @test "test name".
# It is used when a test does not work in podman, either for permanent
# design-related reasons or for hopefully-temporary bug-in-podman reasons.
# (If the latter, please file an issue before adding the skip, and include
# the issue number in your skip message. This makes it possible to remove
# the skip once the issue is fixed).
#
# For both cases, you can list multiple "test names" at the end. This
# is not used much right now, but will be once I file my podman-remote PR
# because there are some cases where the same issue affects up to fifty
# different bud.bats tests.

# Some of the podman tests in CI expects exit code 125, which might not be true
# since exit code from runtime is relayed as it is without any modification both
# in `buildah` and `podman`. Following behviour is seen when PR https://github.com/containers/buildah/pull/3809
# added a test here https://github.com/containers/buildah/blob/main/tests/bud.bats#L3183
# which relays exit code from runtime as it is, in case of both `podman` and `buildah`.
# However apart from this test case no other test case was able to trigger this behavior
# hence marking this test as an anomaly. Since its debatable if we should override this
# returned error number or not hence adding a note here.
