# Purpose:
#   WL#3734 Test: slave group execution 
# Testing slave group execution: stop in middle of the group 
# (of events) should be immpossible on slave.
# Group of events means set of statements between BEGIN/COMMIT
# for transactional engines or a statement for 
# non-transactional engines that fires triggers and 
# affects to another tables.
# Implementation of slave stop in middle of the group:
#   Delete the table on slave before start of the group 
# on master where this table is participant of the group.
# So sql thread will failed inside of the group.
# Expected results:
# 1. For non-transactional engines w/o PK slave should trying 
# to complete executing of the group.
# 2. For non-transactional engines slave should stop on
# start position of the group.
