################################################################################
# In this test case, we verify if some DDL statements implicitly commit a
# transaction and are written directly to the binary log without going
# through either the Statement- or Transactional-Cache.
#
# As any statement that goes through a cache is written to the binary log
# wrapped in a BEGIN...COMMIT, we proceed as follows:
#
# - create a transaction and insert some values into a transactional table.
# - execute a DDL statement that is supposed to implicitly commit the previous
# transaction.
# - Check in the binary log for a COMMIT mark which is supposed to be written
# before the DDL statement.
# - Check in the binary log if the DDL is not wrapped by a BEGIN..COMMIT.
#
# For further details, please, read WL#2687 and WL#5072.
