如何为在单个请求上创建多个数据库对象的 API 视图编写测试？

Question

我的数据库中有事务table，我 API 根据单个请求在数据库中创建多个事务行，

我已经编写代码来测试 API 但不知何故它失败了，下面是我的代码

这是我的序列化程序：

class TransactionSerializer(serializers.ModelSerializer):
    """Transaction Serializer"""
    class Meta:
        """meta class"""
        model = Transaction
        fields = '__all__'
        read_only_fields = ['id', 'user']
        extra_kwargs = {'staff': {'required': True}}

这是我的看法：

 class CreateMultipleTransactionAPIView(APIView):
    """create multiple transactions"""
    def post(self, request):
        """handling post request"""
        serializer = TransactionSerializer(data=request.data,
                                           many=True)
        if serializer.is_valid():
            serializer.save(user=self.request.user)
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

这是我的测试代码失败:

    def test_create_multiple_transactions_errors(self):
        url = reverse('transaction_apis:create_multiple')
        request_data = {'items': [{}]}
        response = self.client.post(url, request_data)
        print(response.content_type)
        self.assertEqual(response.status_code, status.HTTP_400_BAD_REQUEST)

运行测试后的输出：

self.assertEqual(response.status_code, status.HTTP_400_BAD_REQUEST)
AssertionError: 201 != 400

在请求 API 时只需使用 format=json 和对象列表，如下代码

    def test_create_multiple_transactions_errors(self):
        url = reverse('sa_transaction_apis:create_multiple')
        request_data = {
            'service_name': 'S2',
            'service_price': 321,
            'payment_type': 'W'
        }
        response = self.client.post(url, request_data)
        self.assertEqual(response.status_code, status.HTTP_400_BAD_REQUEST)

    def test_create_multiple_transactions_success(self):
        url = reverse('sa_transaction_apis:create_multiple')
        datas = list()
        datas.append({
            'service_name': 'S2',
            'service_price': 321,
            'staff': self.staff.pk,
            'created_at': "2016-10-12T12:31:08.553139",
            'payment_type': 'W'
        })
        response = self.client.post(url, datas, format='json')
        self.assertEqual(response.status_code, status.HTTP_201_CREATED)
