[Matplotlib-users] Unit testing code that generate matplotlib plots

[Wes M. <wes...@gm...>]

Hi guys,

Is there a common practice for unit testing code that creates
matplotlib plots? I'm mainly just interested in code coverage versus
correctness (making sure the code *works*) for now. I guess one way
would be to disable the GUI backend so GUI elements don't get created
(if the user is running the test suite from inside IPython in pylab
mode, for example). Any tips or pointers to projects that do this
would be very helpful.

Thanks,
Wes
