Test Processor Module
=====================

This module contains the definition of the TestListingFixture fixture class.
This fixture is used for handling the actual spawning of worker processes
for running tests, or listing tests. It is constructed as a `fixture`_ to
handle the lifecycle of the test id list files which are used to pass test ids
to the workers processes running the tests.

.. _fixture: https://pypi.python.org/pypi/fixtures

In the normal workflow a TestListingFixture get's returned by the
:ref:`api_config_file`'s get_run_command() function. The config file parses the
config file and the cli options to create a TestListingFixture with the correct
options. This Fixture then gets returned to the CLI commands to enable them to
run the commands.

The TestListingFixture class is written to be fairly generic in the command
it's executing. This is an artifact of being forked from testrepository where
the test command is defined in the configuration file. In stestr the command is
hard coded ``stestr.config_file`` module so this extra flexibility isn't really
needed.
