gevent spawn出來的task，可以用以下三個decorate來綁定, task做完後的callback

glet = gevent.spawn(task, ...)


@glet.link
def on_finish(glet):
  pass

有時候在跑unittest的時候，需要一些前置作業，多半可以寫在setUp或tearDown上

pytest提供fixture, 可以定義每一次的跑unitest的session, module, class, method，都預先跑某個準備函式

例如，我希望跑unittest時先起一個mock database,並在結束時，關掉這個mock database 就可以寫在conftest.py上

#conftest.py 

@pytest.fixture(scope="session", autouse=True)
