# TEST Replication and delay syncing clients - change master test.
|

# TEST
|
|
# TEST Open and start up master and 4 clients. Turn on delay for 3 clients.
|
|
# TEST Switch masters, add data and verify delayed clients are out of date.
|
|
# TEST Make additional changes to master. And change masters again.
|
|
# TEST Sync/update delayed client and verify. The 4th client is a brand
|
|
# TEST new delayed client added in to test the non-verify path.
|
|
# TEST
|
|
# TEST Then test two different things:
|
|
# TEST 1. Swap master again while clients are still delayed.
|
|
# TEST 2. Swap master again while sync is proceeding for one client.
