# Validate that BEFORE, AFTER and BEFORE_AND_AFTER values can only be used on
# group_replication_consistency on ONLINE members.
#
# Test:
# 00. The test requires two servers: M1 and M2.
# 01. Create two tables on each server before start the group.
# 02. Lock table t1 on server2 to block a future update.
# 03. Bootstrap group on server1.
# 04. Execute transactions T1 on server1.
# T1 will block server2 on RECOVERING state.
# 05. Start group on server2, it will be on RECOVERING state.
# 06. Unlock table t1 on server2.
# Member will move to ONLINE state.
# 07. Execute transactions T2 on server1.
# T2 will make server2 move to ERROR state due to
# duplicate key.
# 08. Stop group on server2.
# Member will move to OFFLINE state.
# 09. Clean up.
