Review Comment:
   This was another case where I didn't know what 
`EasyMock.verify(stateManager)` at the end of the method was actually verifying.
   
   I placed 
   
   ```java
   when(stateManager.changelogOffsets())
       .thenReturn(Collections.singletonMap(partition, 60L));
   when(stateManager.changelogPartitions())
           .thenReturn(Collections.singleton(partition));
   ```
   
   back and verified `verify(stateManager).changelogOffsets();`
