The tests that are failing don't have anything to do with the dining module, gonna try to take a look at the code to see if there are any patterns.

Tests look good, I think. Where do the contents of the new JSON files come from, BTW?

I just copied the exact data that would be returned from the Dine on Campus at the specific endpoints called by the sample function calls. I don't have much experience writing tests so I'm not sure if there was anything wrong with my approach.

OK, I'm pretty sure the failing tests are failing because their inputs aren't mocked. The failing tests in lab_test.py, library_test.py, and people_test.py all run the module functions directly (i.e. make HTTP requests) as opposed to calling the function with mocked inputs. All function tests for other modules (that aren't skipped) do mock their inputs, and those are clearly passing. My guess is that real HTTP requests get messed up when the enclosing functions are run from a test environment, probably something to do with shared resources in the test environment.

TL;DR the tests in lab_test.py, library_test.py, and people_test.py all should be rewritten to use mocked inputs instead of making real HTTP requests.
