Comment #5 on issue 1015 by pekka.klarck: Attribute source to be passed on
start/end suite listener methods
http://code.google.com/p/robotframework/issues/detail?id=1015
This issue was updated by revision ba2fd435b05c.
1) Added tests to verify that the source is correct.
2) When running multiple suites at once, the top level suite has no
source. I changed the source passed to listeners to be en empty string
instead of None/null in this special case. Not sure should this have
been also documented in the User Guide.
