Question

我在为一些django视图设置模拟时遇到问题。

backend.py

class Connector(object):
    def get_this():
        ...

    def get_that():
        ...

view_a.py

from backend import Connector

class AView(View):

    def get_context_data(self, **kwargs):
        connector = Connector()
        things = connector.get_this(...)

view_b.py

class BView(View):

    def get_context_data(self, **kwargs):
        connector = Connector()
        things = connector.get_that(...)

text_view_a.py

class ATest(TestCase):
    @mock.patch('backend.Connector')
    def test_simple(self, connector_mock):
        mi = mock.return_value  # The constructor
        mi.get_this.return_value = ...
        mi.get_that.return_value = ...
        response = self.client.get(
            reverse('...view_a'),
        )
        self.assertTrue(mi.get_this.called)

text_view_b.py

class BTest(TestCase):
    @mock.patch('backend.Connector')
    def test_simple(self, connector_mock):
        mi = mock.return_value  # The constructor
        mi.get_this.return_value = ...
        mi.get_that.return_value = ...
        response = self.client.get(
            reverse('...view_b'),
        )
        self.assertTrue(mi.get_that.called)

我所看到的行为是，它们都可以单独运行，但是当运行时只有第一个成功而其余部分失败。基本上它看起来只有第一个模拟设置/使用。我想这与使用自己的导入类副本的视图有关吗？

模拟此类后端类的最佳做法是什么时候？

我自己修好了;我不得不嘲笑使用它的类而不是来自它的地方......

class BTest(TestCase):
    @mock.patch('view_a.Connector')
    def test_simple(self, connector_mock):
        mi = mock.return_value  # The constructor
        mi.get_this.return_value = ...
        mi.get_that.return_value = ...
        response = self.client.get(
            reverse('...view_b'),
        )
        self.assertTrue(mi.get_that.called)

在django unittest中模拟导入的类
