Testing Container Images with Python and Pytest
summary
pytest_container is a pytest plugin that actually pulls, builds, launches and destroys images for tests, exposes a connection to run Testinfra checks, and auto pull/build/launch/cleanup of containers and volumes (including removing anonymous volumes). It finds free host ports and binds them, supports Docker and Podman selectable by env var, can create pods and shared networks, defaults to reusing containers but offers container-per-test, and waits for container health checks before running tests.
