Minitest exit value

[everton]

To incorporate this gem as part of a CI process, the tests suite should return a non-success exit code when coverage failed.

For minitest, ignoring thresholds (considering anything bellow 100% a failure), this block inside the minitest.rb could be enough:

  if $covered.policy.each.flat_map(&:counts).detect { _1&.zero? }
    Kernel.exit(1)
  end

A similar behavior is found in simplecov: https://github.com/simplecov-ruby/simplecov/blob/b6c2d4208a5fa395ce09d7e1d3b074f680ee29b0/lib/simplecov.rb#L239

Do you want to make a PR?

Sure, I will try!

You should check out the coverage tasks that I use for this purpose too:

Basically, 0 or more tasks which generate coverage, and a final task which merges it all together and validates it according to some required percentage: https://github.com/socketry/async/actions/runs/11737730374/job/32699033302

@ioquatix, thanks for the reference sir, I just added the PR #33 using the Covered::Statistics class as you are using in the bake tasks.

I chose to not set the Kernel.exit directly because the #validate! already raises and error and this is enough.
