Seems like we can avoid a bunch of the noisy skipif and imports by using importorskip here:

Suggested change
from PySide6 import QtGui, QtOpenGL
PySide6 = pytest.importorskip("PySide6")
QtGui = PySide6.QtGui
QtOpenGL = PySide6.QtOpenGL

I didn't know about the importorskip trick.

Still need to import the subpackages explicitly, though. PySide6 doesn't import everything automatically.

You can pass a dotted path to importorskip, making this code even shorter:

QtGui = pytest.importorksip("PySide6.QtGui")
# etc

Didn't realize they were subpackages, otherwise I would've made that my original suggestion!

The additional skip can be done later if desired.

I don't love skippable tests because I feel too much complexity is introduced from the lack of symmetry between local and ci builds. For example, there is a potential for the tests to bit-rot if they aren't run frequently enough by devs or the ci runners.

I have updated this to use the pyglet-based test as suggested by @pijyoi (and pyglet is small enough, I think it's fine to add a a test-only dependency) and added a the "always expected to fail" test as suggested by @rparolin. I think this is ready to go.

FYI

See #1210 (comment)

test_graphics_apis.py::test_graphics_api_smoketest is SKIPPED in all CI jobs.

This isn't critical at the moment. However, SWQA stumbled over this test, PR #1210 is for resolving that issue.
