Personally, I think this is overkill. We approach this by making tests
responsible for cleaning and/or setting up any tables they need. So, if
I have to have certain data in my orders table, then I'm responsible for:
# delete all orders and anything dependent on orders, this method is
responsible for knowing what depends on orders and calling
dependent_object.delete_all_cascaded() for those tables. But only one
level deep since the dependent objects are also responsible for taking
care of dependencies.
# create order with sane defaults, pass in parameters to change values
that need to be updated for testing.
