Source: dh-python Version: 5.20230130 Severity: wishlist copy_test_files() defaults to copying "test" and "tests", allowing further customization through pybuild.testfiles. This is great, and a sane default that does the right thing most of the time!
In that spirit, it may make sense to also copy the test runner's configuration by default, as that may customize the test runner in a way that affects test execution. That could be in either direction: making them stricter, looser, or configuring the runner in a way that it works, specifically for the package. For example, for pytest, this config could take the form of pytest.ini and pyproject.toml. Enumerating config files for all may be a bit annoying, so perhaps a sane default could just be to limit this to just pyproject.toml. That could perhaps encourage maintainers to work with their upstreams to migrate the config as well :) A real-world example of this is src:python-structlog, which has in its pyproject.toml: [tool.pytest.ini_options] addopts = ["-ra", "--strict-markers", "--strict-config"] testpaths = "tests" xfail_strict = true filterwarnings = ["once::Warning"] asyncio_mode = "auto" asyncio_mode (for pytest-asyncio) is of particular interest, as that defaults to "strict" and can easily make a test suite fail or succeed. In structlog's case this is handled gracefully, and without it the testsuite just skips the async tests, which is OK, but reduces test coverage. I've worked around this by "tests\npyproject.toml\n" to pybuild.testfiles, but I figured it may make sense for such a config to be the default. Thanks for the consideration! Best, Faidon
