@thaJeztah - I had moved my branch further by pulling in changes from upstream. I see now it would pollute the history with needless commits that cannot be squashed into fewer commits.

I wish to keep the history as clean as possible. So if you feel it is OK, could you please drop all 3 existing commits that are currently attached to this PR. And pull af4e179 from vikramhh:unittests_junit_2

Looks like this PR didn't work, probably because I opened it directly from your fork.

I updated #39998 with those changes, but looks like it doesn't work yet (see my comments on that PR)

Let me close this one
