Opening this issue, because a number of tests are being skipped over by pytest. For example, t001_test.py, t002_test.py, etc... are recognized and run properly. However, naming conventions like t004_test_utilarray.py are not being run locally or within the Github actions CI by pytest.
According to the pytest documenation:

This issue affects:
t004_test_utilarray.py,
and t054_test_mfnwt.py through t079_test_cbc_full3D.py
The simplest solution seems to be refractoring these test module names.
