Adding testing

[max-anu]

Added tests for functions/etc which do not require a gpu (i.e. not lavavu)

This is failing with this message:
E ImportError: cannot import name '_LavaVuPython' from 'osmesa' (/home/runner/miniconda3/envs/access-vis-test/lib/python3.12/site-packages/lavavu/osmesa/__init__.py)

I don't know what needs to change to fix this. Does anyone else have thoughts?

Are you getting this error on your machine or on a github runner? If on your machine it shouldn't need osmesa, do you have LV_CONTEXT set?

If the tests are to run on github runners they'll need to install lavavu-osmesa instead of lavavu. I bundled it in the previous release but the latest default lavavu wheels no longer include it as it made them huge and the project is out of space on pypi.
Alternatively just run them on self-hosted, see: https://github.com/ACCESS-NRI/ACCESS-Vis/blob/main/.github/workflows/testing.yaml

This is on the github runner. I changed lavavu to lavavu-osmesa in ci/environment-3.x.yml. It now shows a different error.

You could try adding moderngl to deps and set LV_CONTEXT: moderngl in env instead of osmesa

Nice work! Finally got both the CI suites to pass with some tweaks
