A fully commented, non-functional reference scenario (install + remove sub-scenarios) for the fictional example playbook. It demonstrates how to structure a Molecule test and what to assert: behaviour and end state (service running, the app using the configured value, API-managed state) rather than the role's own mechanics. Copy it as the starting point for a new playbook's test.
- discover VM IPs from the host ARP table (--source arp) instead of the DHCP lease table: a stable MAC across recreate cycles accumulates several unexpired leases, so --source lease returned stale addresses - raise the cloud-image download timeout to 120s; the 10s default times out when one play pulls all images at once over shared bandwidth - refresh the apt cache on Debian/Ubuntu during prepare; the cloud images ship an empty index, so a bare package install could not resolve anything - set a known root password on the throwaway VMs for console debugging
Use the ubuntu-lts-latest osinfo alias since libosinfo has no dedicated 26.04 entry yet; it only seeds hardware defaults and tracks the latest LTS.
- drop obsolete accelerate_timeout from config.yml (accelerate plugin was removed from Ansible) - apply | bool to the container privileged/systemd params - fix the README reference to a non-existent container-create-fail.yml
