BATS and APIv2: more tests and tweaks
- (minor): apiv2 tests: check for full ID Observation made while reviewing #6461: tests were checking only for a 12-character container/image ID in return value. It's actually 64, and we should test for that. This should also minimize confusion in a future maintainer. - podman pause/unpause: new test Runs a 'date/sleep' loop, pauses container, sleeps 3s, restarts, then confirms that there's a 3- to 6-second gap in the logs for the container. - podman healthcheck: new test run a container with healthcheck, test both healthy and unhealthy conditions - podman pod: check '{{.Pod}}' field in podman ps Hey, as long as we have a pod with two running containers, might as well confirm that 'podman ps' returns the expected pod ID.
