如何在django基于类的视图中对测试方法进行单元化？ [英] How to unit test methods inside django's class based views?

问题描述

我需要在django基于类的视图中测试方法和辅助函数。

I need to test the methods and helper function inside a django Class Based View.

请考虑以下基于类的视图：

Consider this Class Based View:

class MyClassBasedView(View):

    def dispatch(self, request, *args, **kwargs):
        ....

    def __get_render_dict():
        d = {}
        ...
        return d

    def my_method(self):
        render_dict =  self.__get_render_dict()
        return render_response(self.request, 'template.html', render_dict)

为了为我的视图编写单元测试，我需要调用内部的方法，直接说 __ get_render_dict（）。我该如何实现？？

In order to write unit tests for my view, I need to call the methods inside, say __get_render_dict() directly. How can I achieve this?.

我尝试过

v = MyClassedBasedView() 
v.dispatch(request,args, kwargs)
v.__method_name()

但这失败了，因为post / get方法中的参数不匹配，即使我在不​​使用URL的情况下调用方法不透明。

but this fails with not matching parameters in post/get method, even though I was calling the method direclty without using URL.

推荐答案

要在单元测试中使用基于类的视图，请尝试从setup_view Latest / testing.html＃django_downloadview.test.setup_view rel = noreferrer>此处。

To use class based views in your unittests try setup_view from here.

def setup_view(view, request, *args, **kwargs):
    """
    Mimic ``as_view()``, but returns view instance.
    Use this function to get view instances on which you can run unit tests,
    by testing specific methods.
    """

    view.request = request
    view.args = args
    view.kwargs = kwargs
    return view

您仍然需要向其提供请求，可以使用 django.test.RequestFactory ：

You still need to feed it a request, you can do this with django.test.RequestFactory:

    factory = RequestFactory()
    request = factory.get('/customer/details')

然后可以对您的方法进行单元测试：

You can then unittest your methods:

v = setup_view(MyClassedBasedView(), request) 
v.method_name()
