Python 在django中使用无效数据进行视图测试时获取断言错误

我通过使用无效数据开发测试用例来测试我的webapp。除了一个让我非常烦恼的断言错误之外，一切都正常。我试图阻止一个原告注册，如果一个相同的电子邮件id像他的存在。在这种情况下，相同的表单将在上下文中呈现为错误（请检查下面编写的代码）。但它一直显示断言错误。 这是我的密码：

这是我的视图。py：

def register(request):
    if request.method == 'POST':
        user_form = CustomUserCreationForm(data=request.POST)
        if user_form.is_valid():
            ob = CustomUserCreationForm.register(user_form)
            if ob.is_active is False and ob.is_staff is False:
                return render(request, 'todoapp/waiting.html')
            else:
                return render(request, 'todoapp/admin_success.html')
        else:
            return render(request, 'todoapp/register.html', {'errors': user_form.errors})
    return render(request, 'todoapp/register.html', {'form': CustomUserCreationForm()})

url(r'^register/', views.register, name='register'),

sent_data = {
            'first_name': 'john',
            'last_name': 'doe',
            'email': 'johndoe@gmail.com',
            'password': 'johndoe'
        }
        response = self.client.post(url, sent_data)
        self.assertEqual(response.status_code, 200)
        expected_data = {
            'email': 'User with this Email already exists.'
        }
        self.assertEqual(response.context['errors'], expected_data)

self.assertEqual(response.context['errors'], expected_data)
AssertionError: {'email': [u'User with this Email already exists.']} != {u'errors': {u'email': u'User with this Email already exists.'}}

这是我的URL.py：

def register(request):
    if request.method == 'POST':
        user_form = CustomUserCreationForm(data=request.POST)
        if user_form.is_valid():
            ob = CustomUserCreationForm.register(user_form)
            if ob.is_active is False and ob.is_staff is False:
                return render(request, 'todoapp/waiting.html')
            else:
                return render(request, 'todoapp/admin_success.html')
        else:
            return render(request, 'todoapp/register.html', {'errors': user_form.errors})
    return render(request, 'todoapp/register.html', {'form': CustomUserCreationForm()})

url(r'^register/', views.register, name='register'),

sent_data = {
            'first_name': 'john',
            'last_name': 'doe',
            'email': 'johndoe@gmail.com',
            'password': 'johndoe'
        }
        response = self.client.post(url, sent_data)
        self.assertEqual(response.status_code, 200)
        expected_data = {
            'email': 'User with this Email already exists.'
        }
        self.assertEqual(response.context['errors'], expected_data)

self.assertEqual(response.context['errors'], expected_data)
AssertionError: {'email': [u'User with this Email already exists.']} != {u'errors': {u'email': u'User with this Email already exists.'}}

这是我的测试。py：

def register(request):
    if request.method == 'POST':
        user_form = CustomUserCreationForm(data=request.POST)
        if user_form.is_valid():
            ob = CustomUserCreationForm.register(user_form)
            if ob.is_active is False and ob.is_staff is False:
                return render(request, 'todoapp/waiting.html')
            else:
                return render(request, 'todoapp/admin_success.html')
        else:
            return render(request, 'todoapp/register.html', {'errors': user_form.errors})
    return render(request, 'todoapp/register.html', {'form': CustomUserCreationForm()})

url(r'^register/', views.register, name='register'),

sent_data = {
            'first_name': 'john',
            'last_name': 'doe',
            'email': 'johndoe@gmail.com',
            'password': 'johndoe'
        }
        response = self.client.post(url, sent_data)
        self.assertEqual(response.status_code, 200)
        expected_data = {
            'email': 'User with this Email already exists.'
        }
        self.assertEqual(response.context['errors'], expected_data)

self.assertEqual(response.context['errors'], expected_data)
AssertionError: {'email': [u'User with this Email already exists.']} != {u'errors': {u'email': u'User with this Email already exists.'}}

以下是错误：

def register(request):
    if request.method == 'POST':
        user_form = CustomUserCreationForm(data=request.POST)
        if user_form.is_valid():
            ob = CustomUserCreationForm.register(user_form)
            if ob.is_active is False and ob.is_staff is False:
                return render(request, 'todoapp/waiting.html')
            else:
                return render(request, 'todoapp/admin_success.html')
        else:
            return render(request, 'todoapp/register.html', {'errors': user_form.errors})
    return render(request, 'todoapp/register.html', {'form': CustomUserCreationForm()})

url(r'^register/', views.register, name='register'),

sent_data = {
            'first_name': 'john',
            'last_name': 'doe',
            'email': 'johndoe@gmail.com',
            'password': 'johndoe'
        }
        response = self.client.post(url, sent_data)
        self.assertEqual(response.status_code, 200)
        expected_data = {
            'email': 'User with this Email already exists.'
        }
        self.assertEqual(response.context['errors'], expected_data)

self.assertEqual(response.context['errors'], expected_data)
AssertionError: {'email': [u'User with this Email already exists.']} != {u'errors': {u'email': u'User with this Email already exists.'}}

断言错误是由于

左侧=右

在这里，您希望将消息作为响应进行比较，您可以检查此特定情况

self.assertEqual(response.context['errors']['email'][0], expected_data['email'])

或

当错误出现在列表中时，您可以更好地修改预期的_数据

expected_data = {
            'email': [u'User with this Email already exists.']
        }

self.assertEqual(response.context['errors'], expected_data)

---

关键是您可以看到实际返回的响应，并从现在开始构建预期数据。

@khelwood naa它仍然不起作用。在断言错误中，其中一个dict包含映射到列表的字符串。另一个包含映射到dict的字符串。它们都与您发布的代码中的

预期\u数据

dict不匹配。
