Hi, Devin! Taking a look at your example repository, I can’t see anything that would prevent Test.Unit from being found. Try a full PureScript build from the command line (npm run build), and see if Test.Unit shows up then. Take a look at the “output” directory and see if you can find the compiled Test.Unit module.

I’ve got a much more complete example in progress right now here: https://github.com/bkonkle/purescript-manifold-todomvc/

Take a look, and hopefully a little tinkering will help you get through the roadblock!
