python - 动态创建对象的 Doctest

Question

测试这样的代码的最佳方法是什么(下面的代码显然失败了，因为每次都在不同的 block 中创建对象):

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

我想你想像这样使用省略号:

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