Hi all, is it possible to use the @image_comparison decorator for tests generated within a unittest.TestCase class? With my attempts so far the decorator was indeed instanicated at run time but the test was not called, i.e. the test would allways pass... Running the test with decorator from outside the class works fine. Any idea? Thanks, Fabien

Thomas Robitailles pytest image comparison plugin might also be of interest https://github.com/astrofrog/pytest-mpl Jens tor. 30. jul. 2015 kl. 14.43 skrev Thomas Caswell <tca...@gm...>: > > Paul Hobson expressed interest in making it easier to use the image > comparison tests out side of the mpl test suite > > Tom > > On Thu, Jul 30, 2015, 9:28 AM Fabien <fab...@gm...> wrote: > >> Hi all, >> >> is it possible to use the @image_comparison decorator for tests >> generated within a unittest.TestCase class? >> >> With my attempts so far the decorator was indeed instanicated at run >> time but the test was not called, i.e. the test would allways pass... >> Running the test with decorator from outside the class works fine. >> >> Any idea?

Fabien, The @image_comparison operator is still somehwat of a black box for me. But I can confirm your observation that it only works on top-level test functions, not within a class. It's on my long, and slowly shifting backlog of things to try to improve. -paul On Thu, Jul 30, 2015 at 6:47 AM, Jens Nielsen <jen...@gm...> wrote: > Thomas Robitailles pytest image comparison plugin might also be of > interest > https://github.com/astrofrog/pytest-mpl > > Jens > > tor. 30. jul. 2015 kl. 14.43 skrev Thomas Caswell <tca...@gm...>: > >> >> Paul Hobson expressed interest in making it easier to use the image >> comparison tests out side of the mpl test suite >> >> Tom >> >> On Thu, Jul 30, 2015, 9:28 AM Fabien <fab...@gm...> wrote: >> >>> Hi all, >>> >>> is it possible to use the @image_comparison decorator for tests >>> generated within a unittest.TestCase class? >>> >>> With my attempts so far the decorator was indeed instanicated at run >>> time but the test was not called, i.e. the test would allways pass... >>> Running the test with decorator from outside the class works fine. >>> >>> Any idea?

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!!!
