I did as you said. The issue is actually one that I now recall I
reported last January
http://tinyurl.com/5r6jm6
When a test fails and another test then runs, it dies because the
transaction is in error. The field with too many chars fails and that
causes the next test to raise an error. If you switch the backend to
SQLLite for example you don't get any errors.
Funnily enough, I can stop that happening by using the solution given
at::
http://www.stereoplex.com/two-voices/django-unit-tests-and-transactions
Although the comments to that article imply that Django's own unit
test framework should be doing this?
I think I have two questions now:
1. Is this a bug? Surely one test failing shouldn't affect the other
tests? And surely running your unit tests against different backends
should give the same result.
and perhaps much more simply ...
2. How DO you test if an object is going to fail to be saved, before
trying to save it? The validates method appears to have been removed
now.
For the record this is Django from svn using postgres 8.3 and
psycopg2, running on Hardy,
