Hi everyone, I have just released a small plugin for py.test that wraps the image comparison functionality in matplotlib.testing, for use in other packages that use py.test as the testing framework instead of nose:
https://github.com/astrofrog/pytest-mpl The idea is to make it easy to write a test such as: @pytest.mark.mpl_image_compare def test_succeeds(): fig = plt.figure() ax = fig.add_subplot(1,1,1) ax.plot([1,2,3]) return fig which can then be run in three ways: - Running py.test as usual will simply check the tests run but won't check whether the figure is correct. - Running py.test with the --mpl option will make sure that the figure produced by the test is the same as a reference image - Running py.test with the --mpl-generate-path option will generate the reference images from the tests themselves. There are a number of other options, including ways to pass arguments to savefig, customizing the image names, or setting the tolerance for the comparison. All the documentation is contained in the README.md file: https://github.com/astrofrog/pytest-mpl/blob/master/README.md You can install this plugin with: pip install pytest-mpl I would welcome any feedback and/or contributions!
