Ability to focus on some tests...

[ijcd]

It would be nice if we could focus on some tests for a brief time:

@tag wip
test "should do foo" do
...
end

Ideally it would only run tests marked with some tags (if present) otherwise it should fall back to running everything as it normally does.

This would be a feature of ExUnit rather than this project, no?

[ijcd]

It could be implemented there, but it might be simpler to have something like this in test.watch:

  config :mix_test_watch,
    tasks: [
      ["test --only wip", stop_on_failure: true],
      "test",
      "credo",
      "dialyzer",      
    ]

Something like this would allow for varying workflows.

I think this should be an ExUnit feature.
