We have been trying to add unit tests to Social Post for almost a year. There is an open Pull Request right now. Your task is to add tests for 1 or 2 pieces of the project; they don't have to be big though. You can take a look at what's currently testing (Social API). Also, there's a pastebin with instructions about testing in general and how to think about unit testing.

Deliverables: Push your changes to the current Pull Request
