buildah-bud tests: simplify
Experience this week has shown that managing .diff files is too difficult for humans, and too fragile. Opportunities for errors abound. So, let's try to minimize the diffs. We can't eliminate the diffs to helpers.bash: those are true code changes that are absolutely required for running tests using podman instead of buildah. We need to carry those ourselves: they are not appropriate for the buildah repo itself. What we can do is simplify the patching of bud.bats. That is fragile, because bud.bats changes often, and context- sensitive git patch files can easily get confused. Recognizing that the changes to bud.bats fall under two types: - tests that are skipped - tests in which podman error messages differ from buildah's ...we now have a new script, apply-podman-deltas, which is (I hope) much user-friendlier. It understands two directives: errmsg - alter the expected error message skip - skip a test Both operate based on a bats test name. The test name must match exactly. These directives use 'sed' to update bud.bats. If any directive fails, the script will keep going (so you get as many errors as possible in a run), then exits failure. Instructions (README.md) now explain the process for dealing with all expected test failures. (Sneak checkin: add '--filter=NAME' option to test runner, allowing for targeted and much shorter test runs). Signed-off-by: Ed Santiago <santiago@redhat.com>
