But I still feel like I'm missing some nuance here. Isn't CollectionHandler's use of DeleteReplicaPropertyAPI under-the-hood just as much of an "implementation detail" as DeleteReplicaPropertyAPI's use of the overseer? I very much disagree. The *API classes are *the* primary internal API going forward. We want to test that some old V1 API thing will call it. Whatever the *API class does internally is an implementation detail. Today it talks to the Overseer, tomorrow, lets remove the Overseer :-). I'd rather no test test Overseer message crafting because that cements the Overseer into Solr further. -- This is an automated message from the Apache Git Service.
