+Testing
+=======
+
+General guidelines for writing good tests:
+
+- doctests always assume ``import networkx as nx`` so don't add that
+- prefer pytest fixtures over classes with setup methods.
+- use the ``@pytest.mark.parametrize``  decorator
+- use ``pytest.importorskip`` for numpy, scipy, pandas, and matplotlib b/c of PyPy.
+  and add the module to the relevant entries below.
