If I set the fail point on isMaster, it works:
ruby-driver-rs:SECONDARY> db.adminCommand({configureFailPoint:'failCommand',data:{failCommands:['isMaster'],closeConnection:true},mode:{times:1}})
{
"ok" : 1,
"$clusterTime" : {
"clusterTime" : Timestamp(1572910119, 1),
"signature" : {
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
"keyId" : NumberLong(0)
}
},
"operationTime" : Timestamp(1572910119, 1)
}
ruby-driver-rs:SECONDARY> db.runCommand({isMaster:1})

If I set the same fail point on ismaster, it does not work:

Since "ismaster: 1" is a recognized command, I expect a fail point set on "ismaster" to affect "ismaster: 1" command.
Although I personally strive to use consistent case, it will probably be better user experience if fail point on isMaster triggered on ismaster and vice versa.
