Given a backend of postgres and a simple test to test that, for
example, your model does not accept fields with more characters than
it should ... how do you do it?
I have a part database which has two fields - code and description. e.g.
class Part(models.Model):
code = models.CharField(max_length=15)
description = models.CharField(max_length=50)
I want to make sure that a code field can't have more than 15 chars.
Even if I just greedily swallow the exception::
def testPartCodeBad(self):
"""Reject our bad code"""
part = Part()
part.code = '1234567890123456'
part.description = 'AAAAAA'
try:
part.save()
except:
pass
I still end up with
Destroying old test database...
Creating test database...

.Error: Database test_taiko couldn't be flushed. Possible reasons:
* The database isn't running or isn't configured correctly.
* At least one of the expected database tables doesn't exist.
* The SQL was invalid.
Hint: Look at the output of 'django-admin.py sqlflush'. That's
the SQL this command wasn't able to run.
The full error: current transaction is aborted, commands
ignored until end of transaction block
What it actually means is, you stuck 16 chars where only 15 chars were allowed.
Is this testable?
