'''This file realize the function of how to run posca.
In this file, The first thing is to read testcase config
for example: you could run this by use
posca_run('testcase', "Which testcase you will run")
posca_run('teststory', "Which story you will run")
and if you run "python run_posca", this will run testcase,
posca_factor_system_bandwidth by default.'''
