Hi,
I've been struggling with writing tests for a Child object that has
a mandatory Parent. The problem is usually around the Child having
something like
parent_id = Column(Integer, ForeignKey('parents.id'), nullable=False)
Probably very sensible from an application viewpoint but testing always
breaks because it only creates one object at a time.
I'm not sure if it is the right way, but this seemed to work for testing
the Child.
class TestChild(ModelTest):
klass = model.Child
test_parent = model.Parent()
attribs = dict(
parent = test_parent
...and so on. SQLAchemy is happy because there is not a null for
parent_id and I can actually test the Child object.
Someone should hopefully confirm this is how you do this sort of
testing. It works, but it doesn't mean it should work (or you should do
it that way)
