/**
|
|
* This tests tries to check that a ReplicaSetMonitor initialized with a
|
|
* replica set seed that has none of the nodes up will be able to recover
|
|
* once the replica set come back up.
|
|
*
|
|
* ReplSetMonitor is tested indirectly through mongos. This is because
|
|
* attempting to create a connection through the Mongo constructor won't
|
|
* work because the shell will throw an exception before the mongo shell
|
|
* binds the variable properly to the js environment (in simple terms,
|
|
* the connection object is never returned when it cannot connect to it).
|
|
* Another reason for using mongos in this test is so we can use
|
|
* connPoolStats to synchronize the test and make sure that the monitor
|
|
* was able to refresh before proceeding to check.
