Tests fail on a default bare project

[Rory McCann]

Hi all,

I'm trying to set up django-lean for my own project, and on a bare site,
the tests are failing.

My settings.py is here http://pastebin.com/vR5s3FCB

The test error I'm getting is

Looking at the code is telling me that it's failing after trying to do
update_experiment_reports.

I have no apps created/installed. I followed the Installation section
just after doing 'django-admin createproject X'.

I'm running this on an update Ubuntu 9.10 Karmic laptop.

Any advise?

It's probably because the Engagement report is not generated if you do
not define an engagement calculator in your settings.

The test should probably be modified to temporarily patch the settings
to define a dummy engagement function and then restore the previous
value.

Here is a snippet that we use in our production code.

@contextmanager
def patch(namespace, name, function):
"""Patches `namespace`.`name` with `function`."""
try:
original = getattr(namespace, name)
except AttributeError:
original = NotImplemented
try:
setattr(namespace, name, function)
yield
finally:
if original is NotImplemented:
delattr(namespace, name)
else:
setattr(namespace, name, original)

Then, in a test, we do:

from __future__ import with_statement
...
with patch(settings, 'NOTIFICATIONS_TRACEBACK', False):
# do some stuff in here

So I suggest adding the 'def patch' above into 'experiments/tests/
utils.py' and then wrapping the offending test case with:

with patch(settings, 'LEAN_ENGAGEMENT_CALCULATOR',
'experiments.testsettings.SimpleEngagementCalculator'):

That ought to do the trick. If it does, submit a pull request and I'll
merge it into the main repo and submit a new egg to PyPi nice and
fast.

Thanks,

Erik
