How about adding unit tests for the method `getDeviceId(UserVmVO vm, Long
deviceId)`?
Things I can currently think of to test:
- `RuntimeException` if param `deviceId` is specified as a negative value
- `RuntimeException` if param `deviceId` is specified as `0L`
- `RuntimeException` if param `deviceId` is specified as a value greater
than the "max-device-id"
- `RuntimeException` if param `deviceId` is specified as reserved id `3L`
- `RuntimeException` if param `deviceId` is specified as an id that is
already in use
- `RuntimeException` if param `deviceId` is specified as `null` and all
device ids are in use
- returns id specified in param `deviceId` when not `null` and the id is
not in use
- returns lowest available id when param `deviceId` is specified as `null`
(all of the above are from my understanding of how the method should behave)
