########################################################################################
#    This test verifies if the binlog is not corrupted when the cache buffer is not
#    big enough to accommodate the changes and is divided in five steps:
#
#    1 - Single Statements:
#    1.1 - Single statement on transactional table.
#    1.2 - Single statement on non-transactional table. 
#    1.3 - Single statement on both transactional and non-transactional tables.
#    In both 1.2 and 1.3, an incident event is logged to notify the user that the
#    master and slave are diverging.
#
#    2 - Transactions ended by an implicit commit.
#
#    3 - Transactions ended by a COMMIT.
#
#    4 - Transactions ended by a ROLLBACK.
#
#    5 - Transactions with a failing statement that updates a non-transactional
#    table. In this case, a failure means that the statement does not get into
#    the cache and an incident event is logged to notify the user that the master
#    and slave are diverging.
