Test that something is expected to fail actually fails
Estimated time: 10 min
time_range may still work when end_time is before start_time, but that may make overlap_time not working as expected.
Ensure that your main code stops this. Modify time_range to produce an error (ValueError) with a meaningful message when a "backwards" time_range is passed to it - this is called input validation.
Write a test that tries to generate a time range for a date going backwards.
Use pytest.raises to check for that error in the test.
