+Testing
+-------
+
+To test the pyqtgraph library, clone the repository, and run `pytest pyqtgraph`.  For more thurough testing, you can use `tox`, however the [tox-conda](https://github.com/tox-dev/tox-conda) plugin is required.  Running `tox` on its own will run `pytest pyqtgraph -vv` on it's own, however if you want to run a specific test, you can run `tox -- pyqtgraph/exporters/tests/test_svg::test_plotscene` for example.
