+#       testing of the formula's behaviour. If possible, try to refrain from
+#       the classical "chosing all the instances because I want to test on
+#       another/all distro/s" trap: it will just add time to the testing (see
+#       the discussion on #121).  As an example, the set chosen below covers

+#       three supported Saltstack versions with python2 and 3."
+#       As for `kitchen.yml`, that should still contain all of the platforms,
+#       to allow for comprehensive local testing
