pytest-forked 1.0.1

run tests in isolated forked subprocesses

Warning

this is a extraction of the xdist –forked module, future maintenance beyond the bare minimum is not planned until a new maintainer is found.

This plugin does not work on Windows because there’s no fork support.

• --forked: run each test in a forked subprocess to survive SEGFAULTS or otherwise dying processes.

Installation

Install the plugin with:

pip install pytest-forked

or use the package in develope/in-place mode with a checkout of the pytest-forked repository

pip install -e .

Usage examples

If you have tests involving C or C++ libraries you might have to deal with tests crashing the process. For this case you may use the boxing options:

py.test --forked

which will run each test in a subprocess and will report if a test crashed the process. You can also combine this option with running multiple processes via pytest-xdist to speed up the test run and use your CPU cores:

py.test -n3 --forked

this would run 3 testing subprocesses in parallel which each create new forked subprocesses for each test.
