Tests Fail Locally

[jspeed-meyers]

Describe the bug
The tests fail locally.

To Reproduce
git clone https://www.github.com/iqtlabs/gitgeo
cd gitgeo
pytest

Expected behavior
The tests should pass locally.

Desktop (please complete the following information):

• OS: macOS Catalina
• Python 3.7.4

Additional context
Three tests fail:

FAILED tests/test_gitgeo.py::TestMapping::test_add_contributor_count_to_json - FileNotFoundError: [Errno 2] No such file or directory: 'world.json'
FAILED tests/test_gitgeo.py::TestMapping::test_make_map_from_repo - FileNotFoundError: [Errno 2] No such file or directory: 'world.json'
FAILED tests/test_gitgeo.py::TestMapping::test_make_map_from_csv - FileNotFoundError: [Errno 2] No such file or directory: 'world.json'

Request
@jbenjoseph, can you please either help me fix this or provide a PR? The bug clearly has to do with the Path-related functionality, but I don't understand that functionality that well. Thank you!
