# This test proves notifications are transmitted during mode change.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Start server M1 and M2 with gms_listener service implementation.
# Set M2 member weight to 90. M2 becomes primary during mode change.
# Delete all notifications on M1 and M2.
# 2. Change mode to SPM. M2 becomes primary due to weight.
# Assert ROLE notification is broadcasted.
# 3. Change mode to MPM.
# Assert ROLE notification is broadcasted.
# 4. Change mode to SPM specifying server1 as primary.
# Assert ROLE notification is broadcasted.
# 5. Switch primary.
# Assert ROLE notification is broadcasted.
# 6. Cleanup.
