Testcontainers is a library that starts your test dependencies in a container and stop them after you are done using them. Testcontainers needs Docker socket access for mounting within its reaper, so I made a (for now minimal) different library that does not need Docker socket access. It also works with daemonless Podman.
This is terrific. More folks would be more excited if they realized how much less hassle Podman is than Docker.
