[英]How can mongomock can be use with motor?
我有一個用Tornado和Motor實現的服務器,我遇到過這個pymongo的模擬: https : //github.com/vmalloc/mongomock
為了快速運行它,我真的很喜歡對我的代碼進行單元測試而沒有真正調用DB的想法。
我已經嘗試修補馬達來將調用傳遞給mongomock,就像那樣:
from mock import MagicMock
import mongomock
p = mock.patch('motor.MotorClient.__delegate_class__', new=mongomock.MongoClient)
p1 = mock.patch('motor.MotorDatabase.__delegate_class__', new=MagicMock())
p.start()
p1.start()
def fin():
p.stop()
p1.stop()
request.addfinalizer(fin)
它失敗了:
Traceback (most recent call last):

誰知道怎么做? 或者我在這里浪費時間?
無需實例化magicmock。
p1 = mock.patch('motor.MotorDatabase.__delegate_class__', new=MagicMock)
