Warning clutter can be filtered by adding to “pyproject.toml” in the top-level project directory:
[tool.pytest.ini_options] filterwarnings = ignore::DeprecationWarning
We might choose to suppress DeprecationWarning in a repo’s test suite because the warnings are coming from modules developed by others (e.g. Numpy or Xarray).
However, don’t be too carte blanche about suppressing DeprecationWarning.
