| * Generates expected token range and replica mappings specific to the test case involving a 3 node cluster |

| * eg. |
| * Range 1 - A, B, C |
| * Range 2 - B, C, D |

| * We generate the expected ranges by using |
| * 1) the initial token allocations to nodes (prior to adding nodes) shown under "Initial Ranges" |
| * (in the comment block below), |
| * 2)the "pending node ranges" and |
| * 3) the final token allocations per node. |
| * <p> |
| * Step 1: Prepare ranges starting from partitioner min-token, ending at partitioner max-token using (3) above |
| * Step 2: Create the cascading list of replica-sets based on the RF (3) for each range using the initial node list |
| * Step 3: Add replicas to ranges based on (1) and (2) above |
