Run with --quiet as a test coverage tool?

Is there a way to run without output when using LcovEx as test coverage tool?

Sorry about the late response. The --quiet option actually just changes the Mix shell to the Mix.Shell.Quiet one for the mix lcov task:

lcov_ex/lib/tasks/lcov.ex

Line 19 in aae6032

if opts[:quiet], do: Mix.shell(Mix.Shell.Quiet)

I'm guessing you could try running that configuration in an alias or test_helper.exs, although it would probably just block the whole test process output. Don't know if that's useful for you, or which specific part you wanted to be silent.

I am running mix test.watch --cover, and the extra output from lcov displaces my tests failures by a few lines on the terminal:

It's a small thing, but since those lcov output lines aren't providing me any value in this situation, I would prefer to just have more of the test output visible without having to scroll.

I have this combined with the vscode Coverage Gutters extension to see realtime coverage in my IDE.
