我正在尝试为我的烧瓶应用程序修补公共方法,但它似乎不起作用.
I'm trying to patch a public method for my flask application but it doesn't seem to work.
这是我在 mrss.feed_burner
def get_feed(env=os.environ):
return 'something'
这就是我使用它的方式
@app.route("/feed")
def feed():
mrss_feed = get_feed(env=os.environ)
response = make_response(mrss_feed)
response.headers["Content-Type"] = "application/xml"
return response
这是我没有解析的测试.
And this is my test which it's not parsing.
def test_feed(self):
with patch('mrss.feed_burner.get_feed', new=lambda: '<xml></xml>'):
response = self.app.get('/feed')
self.assertEquals('<xml></xml>', response.data)
我相信您的问题是您没有在正确的命名空间中进行修补.请参阅 where_to_patch 文档了解 unittest.mock.patch
.
I believe your problem is that you're not patching in the right namespace. See where_to_patch documentation for unittest.mock.patch
.
本质上,您正在修补 mrss.feed_burner
中 get_feed()
的定义,但您的视图处理程序 feed()
已经有一个参考原始 mrss.feed_burner.get_feed()
.要解决此问题,您需要修补视图文件中的引用.
Essentially, you're patching the definition of get_feed()
in mrss.feed_burner
but your view handler feed()
already has a reference to the original mrss.feed_burner.get_feed()
. To solve this problem, you need to patch the reference in your view file.
根据您在视图函数中对 get_feed
的使用,我假设您正在像这样导入 get_feed
Based on your usage of get_feed
in your view function, I assume you're importing get_feed
like so
view_file.py
view_file.py
from mrss.feed_burner import get_feed
如果是这样,您应该像这样修补 view_file.get_feed
:
If so, you should be patching view_file.get_feed
like so:
def test_feed(self):
with patch('view_file.get_feed', new=lambda: '<xml></xml>'):
...
