Squish/Using a Decorator to Profile Tests

Use a decorator to profile tests

If your Squish tests are very intensive, or you have hundreds of them, you can run them trough a profiler from time to time. This will enable you to see where you're spending most of your time and will help optimize your efforts.

In order to do this you will need to run your main function through the python profiling package cProfile. For example:

def main():
 pass

import cProfile
profile = cProfile.Profile()
profile.runcall(main)

Depending on your particular configuration, the previous code might lead you to run the test twice. To avoid the repetition, wrap your main function with a decorator instead:

import decorator

decorator.profile

def main():

pass

1. in the decorator file

def profile(func):

def inner():
import cProfile
p = cProfile.Profile()
p.runcall(func)
#do something to report the result

return inner
