# Pre-commit tests.

# To run,

#     tox -e pre-commit

# These tests expect certain test fixtures to be present.  They're not
# included here because they could substantially increase the size of
# the repository, and I don't want to worry about licenses, etc.
#
# The following is a list of files and where they should be sourced:
#
# - _integration_tests/goldens.json_: A set of goldens which should be
#   generated by hand, or using the utility in bin/doc_extract.  Alternatively,
#   they could be generated from darglint and touched up by hand to be
#   made more correct.
# - _integration_tests/max_golden.json_: Should contain a very large golden,
#   crafted to be difficult to parse.
# - _.performance_testrun_: Automatically generated, contains the history of
#   of the performance test runs.  Also used as a cache of previous runs
#   to prevent pre-commit tests from taking too long.
# - _.performance_module_testrun_: Automatically generated, contains the history
#   of the module performance test runs.  (Which are run against the repostitories
#   described below.)
# - _.performance_history_: Automatially generated, records performance history
#   in an easy to view fashion.
# - _integration_tests/repos/_: Cloned whole repos to test against.
#   Ideally, these will be quite large, so it doesn't make sense to include them
#   in the repository.
