# MySQL server stress test system
# ======================================================================
#
##########################################################################
#
# SCENARIOS AND REQUIREMENTS
#
# The system should perform stress testing of MySQL server with
# following requirements and basic scenarios:
#
# Basic requirements:
#
# Design of stress script should allow one:
#
# - to use for stress testing mysqltest binary as test engine
# - to use for stress testing both regular test suite and any
# additional test suites (e.g. mysql-test-extra-5.0)
# - to specify files with lists of tests both for initialization of
# stress db and for further testing itself
# - to define number of threads that will be concurrently used in testing
# - to define limitations for test run. e.g. number of tests or loops
# for execution or duration of testing, delay between test executions, etc.
# - to get readable log file which can be used for identification of
# errors arose during testing
#
# Basic scenarios:
#
# * It should be possible to run stress script in standalone mode
# which will allow to create various scenarios of stress workloads:
#
# simple ones:
#
# box #1:
# - one instance of script with list of tests #1
#
# and more advanced ones:
#
# box #1:
# - one instance of script with list of tests #1
# - another instance of script with list of tests #2
# box #2:
# - one instance of script with list of tests #3
# - another instance of script with list of tests #4
# that will recreate whole database to back it to clean
# state
#
# One kind of such complex scenarios maybe continued testing
# when we want to run stress tests from many boxes with various
# lists of tests that will last very long time. And in such case
# we need some wrapper for MySQL server that will restart it in
# case of crashes.
#
# * It should be possible to run stress script in ad-hoc mode from
# shell or perl versions of mysql-test-run. This allows developers
# to reproduce and debug errors that was found in continued stress
# testing
#
# 2009-01-28 OBN Additions and modifications per WL#4685
