How to debug ExUnit tests with :debugger?

Thanks! The first approach works well.

(Although I was surprised to see a lot of metadata and mangled names for parameters. I was assuming the Elixir layer was more immediate above the Erlang..? But that’s tangential.)

With the second suggesting I didn’t see a way to step through the running code. Are you using that? For me that is pretty essential, in cases where I want to debug at all.
