[BUG] `test_processWM.py` tests not doing anything

[nate-kean]

Describe the bug
Both of the tests in test_processWM.py (test_checkContainment and test_checkContainment2) are set to only do anything if a certain TEST_DIR / 'scenario_1/weather_files/ERA-5_2020_01_03_T23_00_00.nc exists. This file does not exist, however, and so these tests are running without asserting anything.
Maybe I am missing something. Could I be misunderstanding the purpose of these tests?

To Reproduce
Steps to reproduce the behavior:

1. Pause test_processWM.py::test_checkContainment in the debugger
2. See the path stored in getWM.files[0] and note that this path does not exist
3. Observe that the function finishes without ever reaching an assert statement

Expected behavior
These tests should assert something before exiting.
