Common test for checking models with migrations

Registered by Svetlana Shturm on 2013-08-08

All component from Openstack uses models as python representation and migrations as database creation tools.
There is no check for equality of models with databse state.
In fact we have differences in models. We are working on syncing models with migrations, but it will be better to have common test that will check any differences. It can be used in any components of OpenStack.
For checking mysql and postgress should be used.
Objects for testing:
- columns (type, length, default values, nullable),
- constraints (foreign key, unique key, indexes).
