+# Testing

+Running `python setup.py test` will run the extension's automated test suite, but some tests can only be run (presently) by manually starting up the server and clicking around. To do so, from the extension's root directory, run `python tests/__init__.py -i`. The `-i` flag tells the test suite to skip normal testing and instead run the testing application with a test template so you can click around.
