-You can optimize your notebook for testing by checking ``__name__``.  When our tests run ``example.py`` they set the ``__name__`` global to ``"testing"``.  For instance, your notebook should determine whether to import from ``mock_data`` or ``example_data`` using this method (another example: you could also use this method to set ``max_iter``).  It's a bit arbitrary, but try to make your examples run in under ten seconds using the mock data.  You can use our test to verify your example in testing mode:
