# This test only runs when dep >= 0.5 is installed, which is the case for the CI setup.
# When using 'go mod', we allow the test to be skipped in the Prow CI under some special
# circumstances, because it depends on accessing all remote repos and thus
# running it all the time would defeat the purpose of vendoring:
# - not handling a PR or
# - the fabricated merge commit leaves go.mod, go.sum and vendor dir unchanged
# - release-tools also didn't change (changing rules or Go version might lead to
# a different result and thus must be tested)
