nit - A comment here explaining why we need to spy on the service and what we are asserting would be useful.

Approving since the test is functioning properly, but please consider adding more comments to the testShardAlreadyReplicating test case to make it easier to understand. The test is manipulating a lot of objects to achieve a specific scenario and it's hard to quickly grok what each step is doing.

Nitpick - more descriptive variable names, please. cp is hard to decipher at first glance and newCheckpoint is confusing when it's being initialized to be equal to cp

This comment seems out of place now since the replication is not started until multiple lines later. Consider removing it
