I'm using SA underneath a TurboGears 1.0 app. Upgrading SA from 0.4.3
to 0.4.4 causes previously passing unit tests to fail when run in
conjunction with nose's "coverage" plugin -- I've included an example
stack trace below.
The unit tests run just fine when not using nose's --with-coverage
option.
The only other useful information I have is that some basic logging
shows that more of my model code is being run under 0.4.4 than under
0.4.3, when using coverage.
I don't have a small reproduction, nor have I looked at this in lots
of detail - before I do, is this a known issue, or does it can anyone
suggest a good place for me to start debugging?
Thanks!
James
