Most of the tests that end in "Py" are not related to PV at all, e.g., exoReadFile is an SMTK test that uses smtk.testing.TestCase to create a native-OS render window (not a Qt OpenGL render window). But the PV tests, e.g., BathymetryTestChesapeakeBay, create a Qt OpenGL render window (because they use PV for rendering). I am surprised they both fail the same way as the dashboards generally have different behaviors for native-OS vs. Qt render windows on retina displays.
