Re: [Matplotlib-users] @image_comparison decorator and unittests

[Fabien <fab...@gm...>]

Thank you all for your replies. It's not an urgent problem:

1. Jens gave us a link to an existing third party lib, althought it's 
not clear to me how it will work without pytest (i.e. with standard 
unittest).

2. My workaround is simply to use top level test functions as you 
suggest, and the rest works just fine.

It's already awesome enough to be able to test my plots in such an easy 
way!!!

Thanks a lot,

Fabien
