 Smoke tests are a collection of tests defined under the [tests](../tests) path at the root of this repository.
 The sub-directories therein contain fixtures for running simple clusters to assert correct behavior for "happy path" scenarios. These fixtures are mostly self-contained Vagrantfiles describing single-node installations that are easily spun up with Vagrant for the `libvirt` and `virtualbox` providers:
