Write tests

[ekho]

there is no unit tests =(

I was trying to consider this in my PR, however the main obstacle seems to be mocking, or at least providing a stable, unchanging example remote mock repo that doesn't change. In actual fact I have Googled for something and all that returns are API mocking libraries.

Edit: Looks like you don't need to mock a git repo, you can do it all locally

So, is it known:

• Whether git uses some kind of REST API
• Can there be a VPS set up to allow a git repository that never changes? One candidate is AWS codecommit, but this is likely paid. This is likely a more robust solution
  Secondary questions:
  - How would the rakefile test read the remote? Would there be a git init on the test/ directory with submodule config for the VPS added? Then we would be committing refs and hashes I believe 😬 Could instead add reference to setting up a separate dir as the test remote repo and symlink?
