BTW, vtk_dev job does not seem to be correctly pulling the latest vtk.
https://github.com/pyvista/pyvista/actions/runs/18485826814/job/52669082517#step:7:33

It should fail, see #8003

Maybe due to self-hosted pypi ?

Maybe it's due to package caching? Might need to use --no-cache ?

Is this a UV or tox thing? Even the numpy nightlies are not being installed:

That's correct. I'll resolve that. In the mean time, should we delay merging this PR?

[user27182]

This PR adds tests to ensure VTK less than 9.6 has coverage for CubeAxesActor. And those tests are executing and passing. So I think this is good to merge now.
