Question

What is the best way to test code like this (the one below obviously fails while object is created in different block every time):

def get_session(db_name, verbose, test): '''Returns current DB session from SQLAlchemy pool.  >>> get_session('Mmusc20090126', False, True) <sqlalchemy.orm.session.Session object at 0xfb5ff0>  ''' if test:     engine = create_engine('sqlite:///:memory:', echo=verbose)     log_load.debug('DB in RAM.') else:     engine = create_engine('sqlite:///' + 'DB/' + db_name + '.db', echo=verbose)     log_load.debug('DB stored in file: %s' % 'DB/' + db_name + '.db')  # Create TABLES: Structures, Interactions, Interactors, PDB_UniProt, UniProtSeq meta.create_all(engine)  Session = sessionmaker(bind=engine) session = Session()  return session 

Answer 1

I think you want to use ellipsis, like this:

>>> get_session('Mmusc20090126', False, True) #doctest: +ELLIPSIS <sqlalchemy.orm.session.Session object at 0x...>
