Q: Is it possible to send some arguments to monkeyrunner script I start my monkeyrunner script like this
monkeyrunner my_script

but I want to pass some arguments for example like this
monkeyrunner my_script -n 100

and how can I read this value inside the my_script

A: You can access the script arguments in sys.argv list:
#! /usr/bin/env monkeyrunner

import sys

print sys.argv


A: you can use optparse as well.Treat monkeyrunner code as  normal python.
import optparse
options = optparse.OptionParser()
options.add_option("--count", action="store", type="string", dest="count")
opt, args = options.parse_args()
n=opt.count

You can add any number of arguments in convenient way.
