Hi!
I'm FourierTransformer, over the past ten years I've written a couple of libraries in the lua space (ftcsv, lua-simdjson, and tinytoml) and to finally break away from the serialization/parser mold, started working on a new unit testing library.
It's called tested and I've been working on it for the past couple of weeks. It has code coverage, runs test files in parallel, and a fairly ergonomic testing interface that uses the Lua module paradigm.
It's still early days, but if anyone wants to check it out and offer some feedback that would be great!
