Python新手@patch装饰器问题

Question

我尝试通过使用@patch：

修饰测试方法来修补提供程序类

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

然而，当我运行测试时，我收到错误：

*@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).*

有什么想法吗？

使用字符串而不是类。

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