process-wrapper 0.1.2

Context manager for background command-line programs

Process Wrapper is a simple module that executes a command-line style program via a context manager. This is useful if you want your script to do something that relies on a background process.

This module is conceived because of a need to automate the setup and teardown of the Django server when running Robotframework tests. Sample usage would look like this:

#!/usr/bin/env python

import robot
from process_wrapper import run_process

with run_process('python manage.py runserver'):
    robot.run('blackbox_test.robot')

Right now, the process being run is forcefully terminated with a SIGKILL or equivalent signal on context exit. Caution is advised.

To install

Run in command line:

pip install process-wrapper

Dependencies

psutil

Tested Capabilities

• Kills parent and child processes on exit

Thanks to

jung rhew for providing the basis of process teardown code that I used
