Maybe (if we ever encounter a problem) we can do better than that, by actually parsing the file (http://de2.php.net/manual/en/function.token-get-all.php), but it should be solid enough generally.

I don't get why this had $all_tests in the first place. So yeah.

Looks good to me. Thanks sun!

Right. With PSR-0 there is not much flexibility for the filename while holding on namespace + class name.

Committed to 8.x. Thanks. Moving to 7.x.

Views 8.x-3.x test with the above patch fails with the following:

And, at risk of polluting this thread even further, so does Chessboard.

Confirmed this also does not resolve the problem using the script manually locally.
