 Description   

Summary

DRIVERS-2244 enabled testing for find/aggregate with getMore + comment on all topologies. However, testing this feature for change streams is limited to replica sets. The reason for the limitation is described here. In short, on a sharded cluster an additional empty getMore command can be issued, so there should be different number of expected events for replica sets and sharded clusters.

[DRIVERS-1713] introduces a new option ignoreExtraEvents for expectedEventsForClient. When this option is implemented in drivers, we can rewrite
getMore + comment tests and enable them for sharded clusters.

Is this issue urgent?

No

Is this ticket only for tests?
