I'm puzzled by the /./ in that.  I could have understood it *before* testing, since I think this is meant to come from the echo in test, where the promise starts with $(G.testdir)/. - but I don't see how init's promises (the only place testing/. appears) can contribute to the output.
Presumably canonify gets rid of this either way, so I guess it doesn't break the test, but it's confusing to a reader.
