    CRITICAL The source path '/home/zuul/src/github.com/openstack-k8s-operators/edpm-ansible/roles/edpm_kernel/molecule/default/../../../../group_vars/' does not exist.
    WARNING  An error occurred during the test sequence action: 'prepare'. Cleaning up.
    CRITICAL The source path '/home/zuul/src/github.com/openstack-k8s-operators/edpm-ansible/roles/edpm_kernel/molecule/default/../../../../group_vars/' does not exist.
