我删除了用户，并更改了数据= {}部分和问题 仍然存在，我不明白是什么问题。

这是其他应用测试：

$ref

这是我测试的结果：

from django.contrib.auth.models import User
from django.urls import resolve,reverse
from django.test import TestCase
from .views import signup
from .forms import SignUpForm


class SignUpTests(TestCase):
   def setUp(self):
      url = reverse('signup')
      self.response = self.client.get(url)

  def test_signup_status_code(self):
     self.assertEquals(self.response.status_code,200)

  def test_signup_url_resolves_signup_view(self):
     view = resolve('/signup/')
     self.assertEquals(view.func,signup)

 def test_csrf(self):
     self.assertContains(self.response,'csrfmiddlewaretoken')

 def test_contains_form(self):
    form = self.response.context.get('form')
    self.assertIsInstance(form,SignUpForm)

 def test_form_inputs(self):
    '''
    The view must contain five inputs: csrf,username,email,password1,password2
    '''
    self.assertContains(self.response,'<input',5)
    self.assertContains(self.response,'type="text"',1)
    self.assertContains(self.response,'type="email"','type="password"',2)



class SuccessfulSignUpTests(TestCase):
  def setUp(self):
      url = reverse('signup')
      data = {
          'username': 'johndoe','email': 'johndoe@gmail.com','password1': 'user123','password2': 'user123'
      }

      self.response = self.client.post(url,data)
      self.home_url = reverse('home')

  def test_redirection(self):
      '''
      A valid form submission should redirect the user to the home page
      '''
      self.assertRedirects(self.response,self.home_url)

  def test_user_creation(self):
      self.assertTrue(User.objects.exists())

  def test_user_authentication(self):
      '''
       Create a new request to an arbitrary page.
       The resulting response should now have a `user` to its context,after a successful sign up.
      '''
      response = self.client.get(self.home_url)
      user = response.context.get('user')
      self.assertTrue(user.is_authenticated)


class InvalidSignUpTests(TestCase):
  def setUp(self):
      url = reverse('signup')
      self.response = self.client.post(url,{})  # submit an empty dictionary

  def test_signup_status_code(self):
      '''
      An invalid form submission should return to the same page
      '''
      self.assertEquals(self.response.status_code,200)

  def test_form_errors(self):
      form = self.response.context.get('form')
      self.assertTrue(form.errors)

  def test_dont_create_user(self):
      self.assertFalse(User.objects.exists())

问题是我将其应用到平台上来解决这样的问题 有人从hithub复制了我的文件，您可以尝试对我的项目进行测试，并在board / accounts / test.py中记住该问题 他进行了测试，但一开始却失败了，但他说他只是更改了数据部分， 他在SuccessSignUpTests类中将数据部分更改为：

$ python manage.py test
Creating test database for alias 'default'...
