Enhance unit tests #15
Description
Expand variations being tested.
Split tests with multiple variations.
Split test data for each test.
Make future dates using time delta so that we can test for comparisons with the same month and same year, rather than just having dates far into the future. Also add a test for today.
Confirm the inventory used as input is correct for that spot in the script. For example, some have blank audit columns that should have data.
For easier maintenance:
- Use the same df_to_list() function in every test (import from test_script.py)
- Make variable names consistent with script and other tests
- Make dates in the expected output date instead of datetime
- Simplify the number of columns in the inventory if not needed for the test
- Simplify the names of folders and patterns except for the script test
