问题描述
我试图为我的烧瓶应用程序修补一个公共方法,但它似乎不工作。
这里是我的代码 mrss.feed_burner
def get_feed(env = os.environ):
返回'something'
这就是我使用它的方式
@ app.route(/ feed)$ b $ ():
mrss_feed = get_feed(env = os.environ)
response = make_response(mrss_feed)
response.headers [Content-Type] =application / xml
返回响应
这是我的测试,它不是解析。
def test_feed(self):
with patch('mrss.feed_burner.get_feed',new = lambda:' < / xml>'):
response = self.app.get('/ feed')
self.assertEquals('< xml>< / xml>',response .data)
我相信你的问题在于,不要在正确的命名空间中修补。有关 where_to_patch 文档> unittest.mock.patch 。
基本上,您正在修补 get_feed()
in mrss.feed_burner
,但是您的视图处理程序 feed()
已经引用了原来的 mrss.feed_burner.get_feed()
。为了解决这个问题,你需要在你的视图文件中修改引用。
根据 get_feed
在你的视图函数中,我假设你正在导入 get_feed
像这样
view_file.py
from mrss.feed_burner import get_feed
如果是这样,你应该修补 view_file.get_feed
,如下所示:
def test_feed(self):
with patch('view_file.get_feed',new = lambda:'< xml>< / xml>'):
...
I'm trying to patch a public method for my flask application but it doesn't seem to work.
Here's my code in mrss.feed_burner
def get_feed(env=os.environ):
return 'something'
And this is how I use it
@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
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)
I believe your problem is that you're not patching in the right namespace. See where_to_patch documentation for unittest.mock.patch
.
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.
Based on your usage of get_feed
in your view function, I assume you're importing get_feed
like so
view_file.py
from mrss.feed_burner import 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>'):
...
