#672: can't unit-test a model that uses inheritance
--------------------------------+-------------------------------------------
Reporter: [EMAIL PROTECTED] | Owner: anonymous
Type: defect | Status: new
Priority: normal | Milestone: 0.9a2
Component: TurboGears | Version:
Severity: normal | Keywords: nosetests inheritance
--------------------------------+-------------------------------------------
In TurboGears 0.9a1 (which version is not selectable in trac, btw),
nosetests will run the unit tests for a project that doesn't use
inheritance. As soon as you add this line to model.py:
{{{
from sqlobject.inheritance import InheritableSQLObject
}}}
SQLObject raises an exception:
{{{
Traceback (most recent call last):
File
"/usr/local/lib/python2.4/site-
packages/TurboGears-0.9a1-py2.4.egg/turbogears/testutil.py",
line 73, in setUp
item.createTable(ifNotExists=True)
File
"/usr/local/lib/python2.4/site-
packages/SQLObject-0.7.1dev_r1588-py2.4.egg/sqlobject/main.py",
line 1319, in createTable
conn = connection or cls._connection
File
"/usr/local/lib/python2.4/site-
packages/SQLObject-0.7.1dev_r1588-py2.4.egg/sqlobject/dbconnection.py",
line 881, in __get__
return self.getConnection()
File
"/usr/local/lib/python2.4/site-
packages/SQLObject-0.7.1dev_r1588-py2.4.egg/sqlobject/dbconnection.py",
line 893, in getConnection
raise AttributeError(
AttributeError: No connection has been defined for this thread or
process
}}}
Note that this occurs even without actually using inheritance in the
model; just importing InheritableSQLObject is enough to trigger it.
I'm reporting this against the "TurboGears" component because I believe
it's in the testutil code.
This means that TurboGears does not presently support unit testing of a
model that uses inheritance.
