This tests, when failing, only produced a non-informative "exit status 1",
which limits investigating why it failed.
This patch:
- Rewrites the parallel pushes to use an error-group, and asserts each
push to get the failure output of the command.
- Simplifies the Dockerfile that's used for building the test-image,
removing steps that were not needed for the test.
- Adds a cleanup step to make sure the images are deleted after the
test, or if the test fails (although the test-suite should already
handle this).
Before this, a failure looked like:
make BIND_DIR=. TEST_FILTER='TestConcurrentPush' test-integration-cli
=== FAIL: arm64.integration-cli TestDockerRegistrySuite/TestConcurrentPush (5.49s)
docker_cli_push_test.go:159: assertion failed: error is not nil: exit status 1: concurrent push failed with error: exit status 1
check_test.go:476: [dfa779e71fdf8] daemon is not started
--- FAIL: TestDockerRegistrySuite/TestConcurrentPush (5.49s)
With this patch applied:
