@einarwar; I've resolved the merge conflics

[einarwar]

Solid work, good job! Seems like a good change, with more code reusability.

Im sorry for nitpicking on files that were mostly just renamed/moved. Also i am not very knowledgeable about this repo, so some comments might not be relevant.

One thing i would suggest is to add type annotations in the tests where fixtures are used.

@einarwar I've resolved your suggestions and feedback.
Since I've made changes since last you approved this PR, a re-approval is necessary

[einarwar]

LGTM. Once tests pass should be good to go :)
