Implement proper unit testing

[benkohler]

I can get tests to pass on a snapshot from just before the meson conversion, but I cannot get them to pass on meson. Wondering if they pass for anyone else.

The existing tests are for manual testing only as they require inputs. I need to replace those with proper unit tests.

Will keep this as enhancement.
