Hello,
I've been trying to do unit testing with SQLAlchemy and PostgreSQL. In
my model/tables I have two entities state and country, state has a
foreign key relating to country (no problems there).
In my setUp() method I call create_all() for my metadata while in
tearDown() I call drop_all().
Any access of session-bound objects after a commit() are going to access the
database, which means the Session starts a new transaction.
Close out the transactional resources held by your Session after each test
ends. Otherwise PG maintains locks on each table that has been accessed in the
