Wrapper script that would record the execution time of another script with parameters

I have a wrapper script wrapper.py that would time the full execution of benchrun.py.

Let's say I run the benchrun.py using this command:

python benchrun.py --host {host} -f {testfile} -t {number of threads} -s {mongo shell path}

What should I put in the wrapper script to run the benchrun.py script and get the execution time?

First, benchrun.py

import datetime

print ("sleeping now...")
time.sleep(10)
print ("done!")

wrapper:

import os
from datetime import datetime, timedelta

before = datetime.now()
os.system("python benchrun.py")
after = datetime.now()

print ("execution time: {0}".format(after - before))

# timer.py
import time


def timer():
    def wrapper(f):
        def wrapped_f(*args, **kwargs):
            tic = time.perf_counter()  # more precise than '.clock'
            f(*args, **kwargs)
            toc = time.perf_counter()
            method_name = f.__name__
            print('{}: {:.2f}sec'.format(method_name, toc - tic))
        return wrapped_f
    return wrapper

# benchrun.py
from timer import timer


@timer
def benchrun():
    ...

You need to take the time before and after the execution and reduce between them so that you get the execution time;

In the wrapper script:

import time

Before the execute:

before= time.clock()

After the execute:

after = time.clock()
totaltime = after-before

The totaltime is the execute time of benchrun.py script.

Are you using os.system to call the benchrun.py? If so, just set datetime.now() in the begining and after return, and calculate the delta. It should work.
