Where are the tests?

I looked at the release notes for 5.6.14 and then my bzr tree that has been upgraded to 5.6.14. I was able to find changes in bzr based on bug numbers. However for the 5 changes I checked I did not see any regression tests. For the record, I checked the diffs in bzr for these bugs: 1731508, 1476798, 1731673, 1731284, 1730289.

I think this is where the MySQL Community team can step up and help the community understand this. Has something changed? Or did the tests move over here?
