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.
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
