We have 2 servers and One client which registers some keys with durable interest and some without
it. We maintain queues on only One server as redundancy level is one. Following 2 tests have the
two TestCase scenarios

There are two Tests First Test does the follows : // Step 1: Starting the servers // Step 2:
Bring Up the Client // Step 3: Client registers Interests // Step 4: Update Values on the Server
for Keys // Step 5: Verify Updates on the Client // Step 6: Close Cache of the DurableClient //
Step 7: Update the Values // Step 8: Re-start the Client // Step 9: Verify Updates on the Client
// Step 10 : Stop all VMs

For Test 2 the steps are as follows // Step 1: Starting the servers // Step 2: Bring Up the
Client // Step 3: Client registers Interests // Step 4: Update Values on the Server for Keys //
Step 5: Verify Updates on the Client // Step 6: Close Cache of the DurableClient // Step 7:
Update the Values // Step 8: Re-start the Client // Step 9: Send Client Ready Message // Step 10:
Register all Keys (K1, K2 as Non-Durable. K3, K4 as Durable) // Step 11: Unregister Some Keys
(Here K1, K3) // Step 12: Modify values on the server for all the Keys // Step 13: Check the
values for the ones not unregistered and the Unregistered Keys' Values should be null
