@atm1020 I might remove the tests. Seems like they are getting in the way that preventing bugs. You can review the code and let me know what you think. I separated the code a little bit instead of having a large API module

@s1n7ax Due to the refactoring I believe some spy/mock are not being used, which is why the tests are hanging. Therefore, I think runner_spec.lua should also be separated into different files and the tests needs to be rewritten too, but this new structure will makes the tests less complex too.

@atm1020 I'm removing failing tests. I think project is small enough to ignore tests.
