单元测试失败说'WSGIRequest'对象没有属性'city'

我已经编写了一个单元测试来测试api ....它是一个GET调用.... 当我运行它时,我得到了这个错误......继承人追溯......

Traceback (most recent call last):

  File "/home/arindam31/XXX-Name/saul/context_processors.py", line 46, in common_context
    ret_dict['city'] = request.city
AttributeError: 'WSGIRequest' object has no attribute 'city'

继承我的单元测试...

def test_get_cities(self):
    request = HttpRequest()
    request.city = self.c1
    response = self.cl.get('/mapi/latest/cities/')
    content = response.content
    data = json.loads(content)
    for city in City.objects.all():
        assert city.name in data
        assert data[city.name] == city.pk

这里,self.c1是setUp部分中的城市类型对象.... HttpRequest来自django.http。

正在测试的视图如下:

def get_cities(request): 
    print "1"
    if ENABLE_HTTPS_CHECK and not request.is_secure():
        return HttpResponseForbidden()
    if request.method != 'GET':
        return HttpResponseNotAllowed('Not allowed')
    city_map = _get_city_map()
    response = HttpResponse(json.dumps(city_map)
    content_type='application/json')
    response['Cache-Control'] = 'no-cache'
    return response

2 个答案:

答案 0 :(得分:0)

如果要使用自己的请求对象测试视图,则应直接调用视图。您应该使用RequestFactory来创建请求。

正如丹尼尔罗斯曼指出你的请求对象有一个城市属性仍然破坏,除非你有一些中间件可以设置它。您显然有一些中间件需要在saul/context_processors.py中设置它。

使用RequestFactory并直接调用视图会完全绕过中间件,因此您可以专注于测试视图(如果视图支持缺少的中间件)。

如果您的视图要求middelware可以运行,您可能只需要使用测试客户端登录。它有一个会话pr测试方法。

我不知道你在这里要做什么。您实例化一个请求对象,分配一个城市属性,然后继续忽略该对象,只使用标准测试客户端。我不知道为什么你会认为该请求将用于客户端获取。

老实说,虽然我认为你的整个设计都被打破了。您没有在正常的非测试场景中显示您希望如何将参数放入请求中,但通常您会通过POST或GET参数传递它,而不是以某种方式将其注释到请求中。这当然会使测试更容易,因为你可以将字典传递给客户端调用。
