#stdout coverage format

[LeonMatthes]

Introduce the #stdout coverage format.
Prints a coverage report before the test summary.
Useful if you don't want to use a separate coverage provider or your coverage provider is not supported.

Also implements the ability to output more than one coverage format.

Note that I've changed smalltalkCI's .smalltalk.ston to use all supported coverage formats, #coveralls, #lcov and #stdout, so it implicitly tests them each run.

Hi @LeonMatthes,
It looks like testSentButNotImplemented is failing on GemStone. Could you please take a look?

[LeonMatthes]

Ah, it seems Gemstone is actually not loading the Coverage package, which is where the exportResultsIn:-method is implemented. It is called from SmalltalkCI>>#basicTest if coverage is available.

I'll see what I can do to fix this.

[fniephaus]

Thanks!

[LeonMatthes]

@fniephaus . It seems the Merge of the master branch into this fork somehow bricked Pharo builds. Do you have any idea what might be causing this?
I suspect it might be the monticello.meta/version file. I think I just picked one of them... Can they cause issues like this?

[fniephaus]

Yes, very much possible this is caused by corrupted metadata. Can you fix this by hand?

[fniephaus]

Maybe try reproducing locally?

[fniephaus]

There's now a GemStone build running on GitHub Actions, maybe that helps to debug the problem.
