We will apply the same aliasing functionality used for the mongod and mongos isMaster commands in SERVER-49986 to MongotMockIsMaster in the enterprise repository. They implement isMaster for mongotmock.

mongotmock is just a test mock used to test queries talking to mongot (i.e. Atlas Search) and is not used externally.

Similarly to the mongod and mongos isMaster commands, we will decide to return an “isWritablePrimary” response field instead of an “ismaster” response field if we’re running the “hello” command.
