## Design Details

### Test Plan
-1. Unit tests for all controllers
-1. New e2e suite to exercise scaling operations and failure modes.
-1. QE will be asked to have cluster-etcd-operator enabled in all test clusters, especially long-lived clusters
-1. The OpenShift Online environments will always run with cluster-etcd-operator enabled

+#### Scenarios that require testing
+1. If one master is lost, instructions for how to.
+ 1. create a new master that joins the cluster
+ 2. removal of the old master from the cluster
+2. Changes to the etcd-quorum recovery steps
+3. All nodes being shut off at the same time and restarted.
+4. IP address change of a single member
+5. IP address change of all members
+6. debugging and detection when DNS information for all members is lost
+7. debugging and detection when DNS information for one member is lost
+8. Removal of a member from the etcd cluster
+9. Recovery of a member with a bad data-dir.
+10. Addition of a new member when there is significant etcd data.
+11. Upgrade, downgrade, re-upgrade
