# The intent of this test is to verify if the validations that were
# created within the Group Replication plugin in the startup process
# are fully functional.
#
# It will test the dynamic variables:
# - binlog_checksum. It will be set to CRC32 in order to fail.
# - binlog_format. It will be set to STATEMENT in order to fail.
# - transaction_write_set_extraction. It will be set to HASH_ALGORITHM_OFF in
# order to fail.
# - slave_parallel_workers. It will be set to 4 in order to fail.
#
# Test:
# 0. The test requires one server.
#  - Install plugin at startup.
# 1. Set binlog_checksum=CRC32. START GROUP_REPLICATION must fail due to GR
#    incompatible binlog_checksum.
# 2. binlog_format=STATEMENT. START GROUP_REPLICATION must fail due to GR
#    incompatible binlog_format.
# 3. Set transaction_write_set_extraction=OFF. START GROUP_REPLICATION must fail
#    due to GR incompatible binlog_format.
# 4. Set SLAVE_PARALLEL_WORKERS=4, SLAVE_PARALLEL_TYPE=DATABASE. START
#    GROUP_REPLICATION must fail due to GR incompatible SLAVE_PARALLEL_WORKERS.
#  - Set SLAVE_PARALLEL_WORKERS=4, SLAVE_PARALLEL_TYPE=LOGICAL_CLOCK. START
#    GROUP_REPLICATION must fail due to GR incompatible SLAVE_PARALLEL_WORKERS.
# 5. Restore the old configuration values.
