# This test verifies that auto_increment_increment and auto_increment_offset
# are set to its default value of 1, when configure in single primary mode and
# any change to group_replication_auto_increment_increment doesn't affect its
# value.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Start Group Replication on server1
# 2. Save initial value of GROUP_REPLICATION_AUTO_INCREMENT_INCREMENT for server2
# 3. Verify default values of group_replication_auto_increment_increment,
#    auto_increment_increment and auto_increment_offset.
# 4. Start group replication on server2.
# 5. Verify the values of group_replication_auto_increment_increment,
#    auto_increment_increment and auto_increment_offset after starting GR.
# 6. Set group_replication_auto_increment_increment
#    and restart group replication.
# 7. Verify the effects of group_replication_auto_increment_increment
#    on auto_increment_increment on starting GR.
# 8. Verify that auto_increment_offset is still is set to default
# 9. Clean up.
