[TIP] Setuptools and pytest integration issue

[Laszlo Papp]

It seems that the fix in the documentation is this:

     def initialize_options(self):
         TestCommand.initialize_options(self)
-        self.pytest_args = None
+        self.pytest_args = []

     def finalize_options(self):
         TestCommand.finalize_options(self)

Setuptools, at least the latest, does not quite work the way that the
documentation expects it to.
