Update tests with coverage docs with Gradle examples

I think this needs some more work on my end. Thought I had it working, but maybe not yet... Still seeing some issues when running a combination of plain unit tests and tests with @QuarkusTest annotation

[brianwyka]

I'm struggling to get the coverage verification to be aligned with the combination of plain unit tests and @QuarkusTest. The report is unified just fine, but the verification seems to be disjoint.

Probably related to #18726

[brianwyka]

Perhaps the excludes are not taken into account for the verification. I think that may be the disconnect here.

Thanks for this @brianwyka. The overall looks good to me. I left some comments about titles and applying the jacoco plugin

[brianwyka]

Thanks for the review @glefloch . I'll make the changes. However, I think the section on the verification is still inaccurate since it does not work correctly at the moment. Is there any idea there?

[brianwyka]

I believe I found a workaround to the issue (reported on Gradle):
gradle/gradle#14760

Is it okay to document this workaround until its fixed on Gradle side?

[glefloch]

If it's working, I think we can with a reference to the issue

[brianwyka]

@glefloch , updated docs.

[glefloch]

just left few comments. Should be good after that.

[brianwyka]

Should be all set now @glefloch

[glefloch]

Thanks @brianwyka

I force pushed a rebase + squash. Will merge as soon as CI is green.

Thanks @gsmet and @brianwyka !
