# Verify that group_replication_force_members does behave as expected
# when:
# 0) The test requires two servers: M1 and M2.
# 1) A empty value is set on a OFFLINE member. It should succeed.
# 2) A value is set on a OFFLINE member. It should fail.
# 3) A empty value is set on a ONLINE member. It should succeed.
# 4) An IP is set on group with majority reachable. It should fail.
# 5) A empty value is set on a RECOVERING member. It should succeed.
# 6) A value is set on a RECOVERING member. It should fail.
# 7) Restart member with group_replication_force_members set. Group
# Replication automatic start will error out.
# 8) Start Group Replication with group_replication_force_members set,
# start will error out.
# 9) Clear group_replication_force_members, start will work.
# 10) Kill and restart a member to group loose majority.
# 11) Invalid address is set on a ONLINE member with majority unreachable. It
# should fail.
# 12) Address of an UNREACHABLE member is set on a ONLINE member with majority
# unreachable. It should fail.
# 13) IP address is set on a ONLINE member with majority unreachable. It
# should succeed.
# 14) Clean up.
