# This test proves that post recovery value is 0 for
# COUNT_TRANSACTIONS_REMOTE_IN_APPLIER_QUEUE
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Create table t1 and LOCK it on server2.
# 2. Create some transactions on server1.
# 3. Wait for transactions to appear on applier queue on server2.
# 4. UNLOCK tables on server2.
# 5. Wait for applier queue on both servers to be 0.
# 6. Stop GR on server1 and server2.
# 7. Start GR on server1 and server2.
# 8. Confirm COUNT_TRANSACTIONS_REMOTE_IN_APPLIER_QUEUE is 0
# when all servers are online.
# 9. Cleanup.
