 ### Testing
 
 The test suite in this project was specifically built to produce consistent results on every run, regardless of when they run or who is running them. This project uses [VCR](https://github.com/vcr/vcr) to record and replay HTTP requests and responses via "cassettes". When the suite is run, the HTTP requests and responses for each test function will be saved to a cassette if they do not exist already and replayed from this saved file if they do, which saves the need to make live API calls on every test run.
