Ocamlunit emacs minor-mode

Hi.

Here is a first version of this plugin that allows running dune test with an Emacs key stroke.
It shows the test result in a separate buffer and a simple colorized status ‘message’.

While it is possible to run dune in ‘watch’ mode I’d like to manually run tests.

I didn’t find a way to specify individual test modules in dune. Is that possible?
