+Testing
+=======
+ceph-ansible has the ability to test different scenarios (collocated journals
+or dmcrypt OSDs for example) in an isolated, repeatable, and easy way.
+
+These tests can run locally with VirtualBox or via libvirt if available, which
+removes the need to solely rely on a CI system like Jenkins to verify
+a behavior.
