Testing Framework Implementation

[jaredbarranco]

In writing a change for PR #3, knowing if any regression was occuring was difficult. I think implementing unit testing would be a good idea. I'm happy to explore some options out there, but opening this issue in case there's strong opinions one way or another.

After some digging, I see that most Neovim plugins use Busted in one form or another. This template seems to have a bunch of boilerplate that may be helpful.

I'm circling back on this. I've done some reading, and it appears there really isn't a widely supported testing framework with robust documentation and samples. Even with Busted, I'm having troubles setting up basic unit testing.

Hello @jaredbarranco sorry for a delayed response.
I have been able to find some free time and came up with some initial changes. You can see related branch GH-4-add-testing
Please share your thoughts regarding the code and my aproach present in this branch.

On my part I think PlenaryBusted is a best framework to pick for testing since it's using well established busted and on top that plenary is very stable and reliable library itself. As for rate of development, I will try my best to do make changes faster in future
