@ patch 装饰器无法设置提供者
原标题:@patch decorator cannot set Provider

我尝试用 来装饰测试方法, 修补供应商类 :

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

然而,当我做测试时,我得到错误:

*@patch(provider.Provider)*  
*File "builddist.win32eggmock.py", line 1518, in patch*  
*getter, attribute = \_get\_target(target)*  
*File "builddist.win32eggmock.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:devsrc	est\_my\_unit.py).*

有什么想法吗?

最佳回答

使用字符串代替类 。

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

您的答案的 Te 实际解决方案是, 如果您正在使用导入的类, 您必须使用补丁。 object 。

这两两个是相同的

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

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

选择哪个?

如果您已经拥有了导入的类, 您可以使用它, 它更容易读。 如果您需要导入它来补补, 那么使用字符串
