Okay, I finally finished going through all the tests. Here's what I found... The following just required minor tweaks to get the tests to run: http://classic.zope.org:8080/Collector/2454/view http://classic.zope.org:8080/Collector/2456/view http://classic.zope.org:8080/Collector/2461/view The following let tests run with a newer version of unittest.py: http://classic.zope.org:8080/Collector/2455/view http://classic.zope.org:8080/Collector/2460/view The following are tests that need to be removed because they're no longer valid: http://classic.zope.org:8080/Collector/2462/view The following showed Zope breakage, some of it looked serious :-( http://classic.zope.org:8080/Collector/2457/view http://classic.zope.org:8080/Collector/2458/view http://classic.zope.org:8080/Collector/2459/view http://classic.zope.org:8080/Collector/2464/view Finally, the following relates to teh ZCatalog tests, which I just couldn't get to run: http://classic.zope.org:8080/Collector/2463/view Of course, once all those are out the way, we have a completely passing test suite for Zope :-) cheers, Chris
