-Integrating with setuptools / ``python setup.py test`` / ``pytest-runner``
---------------------------------------------------------------------------
-
-You can integrate test runs into your setuptools based project
-with the `pytest-runner <https://pypi.org/project/pytest-runner/>`_ plugin.
-
-Add this to ``setup.py`` file:
-
-.. code-block:: python
-
-    from setuptools import setup
-
-    setup(
-        # ...,
-        setup_requires=["pytest-runner", ...],
-        tests_require=["pytest", ...],
-        # ...,
-    )
-
-
-And create an alias into ``setup.cfg`` file:
-
-
-.. code-block:: ini
-
-    [aliases]
-    test=pytest
-
-If you now type::
-
-    python setup.py test
-
-this will execute your tests using ``pytest-runner``. As this is a
-standalone version of ``pytest`` no prior installation whatsoever is
-required for calling the test command. You can also pass additional
-arguments to pytest such as your test directory or other
-options using ``--addopts``.
-
-You can also specify other pytest-ini options in your ``setup.cfg`` file
-by putting them into a ``[tool:pytest]`` section:
-
-.. code-block:: ini
-
-    [tool:pytest]
-    addopts = --verbose
-    python_files = testing/*/*.py
-
-
-Manual Integration
-^^^^^^^^^^^^^^^^^^
-
-If for some reason you don't want/can't use ``pytest-runner``, you can write
-your own setuptools Test command for invoking pytest.
-
-.. code-block:: python
-
-    import sys
-
-    from setuptools.command.test import test as TestCommand
-
-
-    class PyTest(TestCommand):
-        user_options = [("pytest-args=", "a", "Arguments to pass to pytest")]
-
-        def initialize_options(self):
-            TestCommand.initialize_options(self)
-            self.pytest_args = ""
-
-        def run_tests(self):
-            import shlex
-
-            # import here, cause outside the eggs aren't loaded
-            import pytest
-
-            errno = pytest.main(shlex.split(self.pytest_args))
-            sys.exit(errno)
-
-
-    setup(
-        # ...,
-        tests_require=["pytest"],
-        cmdclass={"pytest": PyTest},
-    )
-
-Now if you run::
-
-    python setup.py test
-
-this will download ``pytest`` if needed and then run your tests
-as you would expect it to. You can pass a single string of arguments
-using the ``--pytest-args`` or ``-a`` command-line option. For example::
-
-    python setup.py test -a "--durations=5"
-
-is equivalent to running ``pytest --durations=5``.
