AssertionError: False不是真的，测试每次都失败是因为这个原因吗？

我删除了用户并更改了data = {}部分，但问题仍然存在，我不知道问题出在哪里。
这是其他应用程序的测试：
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"', 1)
self.assertContains(self.response, '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())这是我的测试结果：
$ python manage.py test
Creating test database for alias 'default'...

Destroying test database for alias 'default'...问题是，我在修复此类问题的平台上应用，有人从hithub复制了我的文件，您可以尝试在我的项目上运行测试，并记住boards/accounts/test.py中的问题，然后他运行测试，测试一开始失败，但他说他只更改了数据部分，他在SuccessfulSignUpTests类中将数据部分更改为：
data = {
'username': 'johndoe',
'email': 'johndoe@gmail.com',
'password1': 'user123'
'password2': 'user123'
}如果有人想看看我在Github的存储库，这是链接：my project

我想问题出在你的view.py上
def signup(request):
if request.method == 'POST':
form = SignUpForm(request.POST)
if form.is_valid():
user = form.save()
auth_login(request, user)
return redirect('home')首先，你不应该直接使用url name，这是不好的，以防以后你决定重构url。如果使用的方式不同，url应该是相对的，如/home
最好使用reverse。因此请将return redirect('home')替换为
return redirect(reverse('home'))您必须添加以下导入
