# The intent of this test is to verify if the validations that were
# created within the Group Replication plugin in the startup process

# It will test binlog disabled failure.

# Test:
# 0. The test requires one server.
#  - Disable log_bin in option file.
#  - Install plugin at startup.
# 1. START GROUP_REPLICATION must fail due to GR incompatible value.
