Is there a way to run coverage reports on a running application instead of through mix test --cover? We’ve got a E2E test suite that I’d like to develop some metrics on and see how much of our Elixir application is getting exercised by it, but its not super obvious to me how to do that easily.

Not as far as I’m aware. I’ve been doing such coverage reports by extensive integration tests.

Yeah, but looking at the source code it doesn’t look too bad to write a custom task that’ll get the job done.
