# ==== Purpose ====
#
# This test checks if an event that is drop implicitly by the scheduler is
# written to the binlog.
#
# ==== Implementation ====
#
# The event is first created on the master.
# The test sleeps for enough time so that, when the scheduler is enabled,
# the event is implicitly dropped because its start and end times have passed.
# The slave is synchronized with the master to log this drop.
# Finally, another event is created to check if the implicit drop was successful
# as it will fail on the slave synchronization, otherwise.
