[~rustyrazorblade] I implemented some dtests and below is the sample output:
{code:java}
Stats for all nodes:
    Live: 4
    Joining: 0
    Moving: 0
    Leaving: 0
    Unreachable: 0
Data Centers:
    dc1 #Nodes: 2 #Down: 0
    dc2 #Nodes: 2 #Down: 0
Keyspaces:
    system_schema -> Replication class: LocalStrategy {}
    system -> Replication class: LocalStrategy {}
    system_traces -> Replication class: SimpleStrategy {replication_factor=2}
    system_distributed -> Replication class: SimpleStrategy {replication_factor=3}
    system_auth -> Replication class: SimpleStrategy {replication_factor=1}
    ks1 -> Replication class: NetworkTopologyStrategy {dc2=5, dc1=3}
    ks2 -> Replication class: NetworkTopologyStrategy {dc2=5, dc1=3}
Cluster Information:
    Name: test
    Snitch: org.apache.cassandra.locator.PropertyFileSnitch
    DynamicEndPointSnitch: enabled
    Partitioner: org.apache.cassandra.dht.Murmur3Partitioner
    Schema versions:
f5abf9f8-8cc6-350f-a128-ab97ea43871d: [127.0.0.4, 127.0.0.3, 127.0.0.2, 127.0.0.1]{code}
I am using assertions to validate the output. Let me know if it looks okay. I will upload
the dtests patch to cassandra-dtests soon.

I implemented tests using assertions to ensure the valid output. Let me know if it looks okay.
