From 95aa9683071cb66f2b3cb1f542710a1ebf6af412 Mon Sep 17 00:00:00 2001 From: Elliott Sales de Andrade Date: Wed, 4 Mar 2020 00:00:56 -0500 Subject: [PATCH] Make test_imagegrid_cbar_mode_edge less flaky. Since parametrizing the test allows it to run in parallel, this makes it flaky, as one process can overwrite the test result image of another. Our standard way for dealing with tests that use the same baseline image is to pass duplicate filenames to `image_comparison`, because that is serialized. --- lib/mpl_toolkits/tests/test_axes_grid.py | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/lib/mpl_toolkits/tests/test_axes_grid.py b/lib/mpl_toolkits/tests/test_axes_grid.py index 58358b686651..0ff4f2b013b6 100644 --- a/lib/mpl_toolkits/tests/test_axes_grid.py +++ b/lib/mpl_toolkits/tests/test_axes_grid.py @@ -12,10 +12,16 @@ # The original version of this test relied on mpl_toolkits's slightly different # colorbar implementation; moving to matplotlib's own colorbar implementation # caused the small image comparison error. -@pytest.mark.parametrize("legacy_colorbar", [False, True]) -@image_comparison(['imagegrid_cbar_mode.png'], +@image_comparison(['imagegrid_cbar_mode.png', 'imagegrid_cbar_mode.png'], remove_text=True, style='mpl20', tol=0.3) -def test_imagegrid_cbar_mode_edge(legacy_colorbar): +def test_imagegrid_cbar_mode_edge(): + # Note, we don't use @pytest.mark.parametrize, because in parallel this + # might cause one process result to overwrite another's. + for legacy_colorbar in [False, True]: + _test_imagegrid_cbar_mode_edge(legacy_colorbar) + + +def _test_imagegrid_cbar_mode_edge(legacy_colorbar): mpl.rcParams["mpl_toolkits.legacy_colorbar"] = legacy_colorbar X, Y = np.meshgrid(np.linspace(0, 6, 30), np.linspace(0, 6, 30)) pFad - Phonifier reborn
