Python的新手@patch裝飾問題

Question

我試圖通過裝飾的測試方法修補供應商類@patch：

class TestMyUnit(unittest.TestCase): 
... 
@patch(provider.Provider,autospec=True) 
def test_init(self, mock_provider): 
    pass 

然而，當我運行測試，我得到的錯誤：

*@patch(provider.Provider)* 
*File "build\bdist.win32\egg\mock.py", line 1518, in patch* 
*getter, attribute = \_get\_target(target)* 
*File "build\bdist.win32\egg\mock.py", line 1367, in \_get\_target* 
*target, attribute = target.rsplit('.', 1)* 
*AttributeError: class Provider has no attribute 'rsplit'* 
*ERROR: Module: test\_my\_unit could not be imported (file: C:\dev\src\test\_my\_unit.py).* 

有任何想法嗎？

使用字符串而不是類。

@patch('provider.Provider', autospec=True) 
def test_init(self, mock_provider): 
    pass
