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 processwrapper 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.
Run in command line:
pip install process-wrapper
Kills parent and child processes on exit
Handles in-context exceptions: It still kills the called process and its children
Processes are properly cleaned up when in-context exceptions occur
Process wrapper will do nothing if it encounters a Process Not Found exception for the parent process and raise all others
Tested to work in win32 and linux2 platforms
Command used to test the module. Includes line and branch coverage:
py.test processwrapper/tests --cov processwrapper --cov-report term-missing --pep8
