@gathuku, FYI, I'm not a maintainer on this project and this issue doesn't have a bounty on it at the moment.
Also, you might want to ping the maintainers just in case they have something to add or even if they truly want test coverage on their project.

Sorry @jemiluv8 , no problem, let me remove my comment.

@jemiluv8 @gathuku I think we could add the simplecov gem to generate a coverage report, but given how early we are with this project, this should be for convenience only at the moment (i.e. a dev writing tests locally can easily see coverage to help them identify important areas that they missed)

In other words, we can set this up, but let's not enforce anything in CI for now.

Nice! @jemiluv8 can I help you with this?
