Django Resolver404错误

Question

在运行python manage.py测试时出现此错误，请帮助我解决此问题

ERROR: test_update_status_table_using_message_table_func (update_status.tests.Up
date_Status_Test)

Traceback (most recent call last):
  File "C:\Users\USER\syuvira\update_status\tests.py", line 67, in test_update_s

^welcome-page/>], [<RegexURLPattern index ^$>]], 'path': 'update-status/show_pos
t'}

这是我的tests.py

def test_update_status_using_index_func(self):

    found = resolve('/update-status/')
    self.assertEqual(found.func, index)

Answer 1

在您的测试代码中触发的Handle the exception resolve函数。

如果URL不能解析，该函数将引发Resolver404异常(Http404的子类)。

def test_update_status_using_index_func(self):
   try:
       found = resolve('/update-status/')
       self.assertEqual(found.func, index)
   except Resolver404:
       self.fail("Couldn't not resolve URL')

Answer 2

另一种测试方法是：

from django.test import Client, TestCase
from django.urls import resolve, Resolver404

from myproject import settings

class TestError404(TestCase):
    def setUp(self):
        self.client = Client()
        self.debug = settings.DEBUG
        settings.DEBUG = False

    def tearDown(self):
        settings.DEBUG = self.debug

    def test_404(self):
        with self.assertRaises(Resolver404):
            resolve('/foo/')
