Hi Giampaolo,
changeset: 53a5a5b8859d user: Giampaolo Rodola' <g.rodola at gmail.com> date: Mon Jan 09 17:10:10 2012 +0100 summary: provide a common method to check for RETRDATA validity, first checking the expected len and then the actual data content; this way we get a failure on len mismatch rather than content mismatch (which is very long and unreadable)
My trick is to convert long strings to lists (with data.split(appropriate line ending)) and pass them to assertEqual. Then I get more readable element-based diffs when there is a test failure.
Another trick I use is this (for example when I don’t want to make too much diff noise, or when I don’t want to build the list of expected results):
self.assertEqual(len(got), 3, got)
unittest will print the third argument on failure.
Regards
