"""Get a test_processor.TestProcessorFixture for this config file
Any parameters about running tests will be used for initialize the
output fixture so the settings are correct when that fixture is used
to run tests. Parameters will take precedence over values in the config
file.
:param options: A argparse Namespace object of the cli options that
were used in the invocation of the original CLI command that
needs a TestProcessorFixture
:param list test_ids: an optional list of test_ids to use when running
tests
:param list regexes: an optional list of regex strings to use for
filtering the tests to run. See the test_filters parameter in
TestProcessorFixture to see how this is used.
:param str test_path: Set the test path to use for unittest discovery.
If both this and the corresponding config file option are set, this
value will be used.
:param str top_dir: The top dir to use for unittest discovery. This
takes precedence over the value in the config file. (if one is
present in the config file)
:param str group_regex: Set a group regex to use for grouping tests
together in the stestr scheduler. If both this and the
corresponding config file option are set this value will be used.
:param str repo_type: This is the type of repository to use. Valid
choices are 'file' and 'sql'.
:param str repo_url: The url of the repository to use.
:param bool serial: If tests are run from the returned fixture, they
will be run serially
:param str worker_path: Optional path of a manual worker grouping file
to use for the run.
:param int concurrency: How many processes to use. The default (0)
autodetects your CPU count and uses that.
:param str blacklist_file: Path to a blacklist file, this file contains
a separate regex exclude on each newline.
:param str whitelist_file: Path to a whitelist file, this file contains
a separate regex on each newline.
:param str black_regex: Test rejection regex. If a test cases name
matches on re.search() operation, it will be removed from the final
test list.
:param bool randomize: Randomize the test order after they are
partitioned into separate workers
:param bool parallel_class: Set the flag to group tests together in the
stestr scheduler by class. If both this and the corresponding
config file option which includes `group-regex` are set, this value
will be used.
:returns: a TestProcessorFixture object for the specified config file
and any arguments passed into this function
:rtype: test_processor.TestProcessorFixture
