Login, Register and Logout test failed AssertionError: 200 != 302 django

Question

我正在尝试为我的登录、注销和注册视图创建测试，但我一直收到此错误 AssertionError: 200 != 302。以下是代码：

型号这是用户模型

from django.db import models
from django.contrib.auth.models import AbstractUser

class User(AbstractUser):
    full_name = models.CharField(max_length=300, null=True, blank=True)
    username = models.CharField(max_length=150)
    email = models.EmailField(unique=True)
    avatar = models.ImageField(upload_to='user-profile-images/', null=True)

    USERNAME_FIELD = 'email'
    
    REQUIRED_FIELDS = ['username']

观看次数 这里是登录注册功能视图

def loginPage(request):
    context = {}
    if request.user.is_authenticated:
        return redirect('home')

    if request.method == 'POST':
        email = request.POST.get('email')
        password = request.POST.get('password')

        try:
            user = User.objects.get(email=email)
        except:
            messages.error(request, 'User does not exist')

        user = authenticate(request, email=email, password=password)

        if user is not None:
            login(request, user)
            return redirect('home')
             
    return render(request,'registration/login.html', context)

def registerPage(request):
    form = SignupForm
    if request.method == 'POST':
        form = SignupForm(request.POST)
        if form.is_valid():
            user = form.save(commit=False)
            user.username = user.username.lower()
            user.save()
            login(request, user)
            return redirect ('home')
        else:
            messages.error(request, 'An error occured during registration')

    return render(request, 'registration/register.html', {'form':form})

def logoutPage(request):
    logout(request)
    return redirect('home')

网址

from django.urls import path
from . import views

urlpatterns = [
    path('login/', views.loginPage, name='login'),
    path('logout/', views.logoutPage, name='logout'),
    path('register/', views.registerPage, name='register'),

]

测试

from django.test import TestCase, Client
from django.urls import reverse
from mydp_app.models import User

class TestViews(TestCase):

    def setUp(self):
        self.client = Client()
        self.login_url = reverse('login')
        self.logout_url = reverse('logout')
        self.register_url = reverse('register')

   def test_register_post(self):
        response = self.client.post(reverse('register'), {
            'full_name': 'Test User',
            'username': 'testuser',
            'email': 'testuser@gmail.com',
            'password': 'testpassword',
            'password2': 'testpassword',
        })
        self.assertEquals(response.status_code, 302)

    def test_login_post(self):
        response = self.client.post(reverse('login'), {
            'email': 'testuser@gmail.com',
            'password': 'testpassword',
        })
        self.assertEquals(response.status_code, 302)

    def test_logout(self):
        self.client.login(email='testuser@gmail.com', password='testpassword')
        response = self.client.post(reverse('logout'), follow=True)
        self.assertEquals(response.status_code, 302)

测试期望状态代码为 200 但它会被重定向。我不断收到此错误 self.assertEquals(response.status_code, 302) AssertionError: 200 != 302

Answer 1

如果您想测试用户是否已成功重定向（响应代码 302），那么您可以删除 follow=True:

    def test_logged_out_user_was_redirected(self):
        self.client.login(email='testuser@gmail.com', password='testpassword')
        response = self.client.post(reverse('logout'))
        self.assertEquals(response.status_code, 302)

如果您想确保它们被重定向到正确的位置，您可以设置 follow=True，将代码设置为 200，然后使用 assertTemplateUsed:

    def test_logout_redirect_succeeds(self):
        self.client.login(email='testuser@gmail.com', password='testpassword')
        response = self.client.post(reverse('logout'), follow=True)
        self.assertEquals(response.status_code, 200)
        self.assertTemplateUsed(self.response, 'my_app/redirect_page.html')`

当您 follow=True 如果成功，响应代码将是 200，而不是 302。

很久以前问过，得知follow=True在pytest中是不行的。在这个过程中，我学到了一些关于使用 follow=True 标志的知识。

我猜现在唯一失败的测试是 test_logout。您的代码是：

        response = self.client.post(reverse('logout'), follow=True)
        self.assertEquals(response.status_code, 302)

如果您有任何问题或需要澄清，请告诉我，我可以解决这个问题。如果我弄错了请告诉我。
