################################################################################
# Validate the correct behaviour when a member joins a group while there is a
# transaction with group_replication_consistency= 'AFTER' ongoing.
#
# Test:
# 00. The test requires three servers: M1, M2 and M3.
# 01. Bootstrap group with M1, add M2.
# 02. Create table t1 with group_replication_consistency= 'AFTER'
# 03. Lock table t1 on server2 to block a future update.
# 04. Execute transaction T1, the transaction will block since
# server2 cannot prepare.
# 05. Execute START GR on M3.
# The member will be in RECOVERING until T1 is complete.
# 06. On M2: Unlock t1.
# 07. server3 will change to ONLINE state.
# 08. Validate data.
# 09. Clean up.
