如何使用boto3为api视图创建测试

如何解决如何使用boto3为api视图创建测试

我创建了以下视图以生成预签名凭证，以将文件上传到s3存储桶，我是测试和boto3的新手，我想知道如何为使用包的视图创建测试喜欢boto3吗？我读到可以模拟generate_presigned_post，但是我在理解如何做到这一点时遇到了麻烦，请你们帮我如何使用pytest测试类似情况？

class AnimesFileCredentials(views.APIView):
    def get(self,request,pk,*args,**kwargs):
        created_by = request.user.id

        serializer = AnimesFileCredentialsSerializer(data=self.request.query_params)
        if serializer.is_valid(raise_exception=True):
            file_name = serializer.validated_data.get('file_name')
            content_type = serializer.validated_data.get('content_type')
            category = serializer.validated_data.get('category')

            animes_file = {
                'anime_id': pk,'document': file_name,'category': category,'created_by_id': created_by
            }
            AnimesFile.objects.create(**animes_file)

            presigned_post = self.generate_presigned_post(file_name,content_type)

            logger.info(f'created document: {file_name} to animes_id: {pk}.')
            return Response(presigned_post)
        return Response(serializer.errors)

    def generate_presigned_post(self,file_name,content_type):
        S3_BUCKET = settings.AWS_MEDIA_STORAGE_BUCKET_NAME
        client = boto3.client('s3',endpoint_url=settings.AWS_S3_ENDPOINT_URL) # localstack dumy url
        presigned_post = client.generate_presigned_post(
            Bucket=S3_BUCKET,Key=file_name,Fields={'acl': 'private','Content-Type': content_type},Conditions=[{'acl': 'private'},{'Content-Type': content_type}],)
        logger.info(f'created presign post to document: {file_name}.')
        return presigned_post

我的测试真的很简单

@pytest.mark.parametrize('animes_file__category',[AnimesFile.ACTION])
def test_animes_file_generate_presigned_post(db,client,anime,animes_file):
    url = reverse('api:files:animes-files',kwargs={'pk': anime.pk})

   response = client.get(url,{'category': category,'content_file': 'application/jpg','file_name': animes_file.document})       
   data = response.json()
   results = data.get('results')[0]
   assert results
   assert results['category'] == category
   assert response.status_code == status.HTTP_200_OK

但是每次我尝试运行时，它都无法说我无法使用错误的凭据连接到s3，并且我认为正确的决定是不使用s3进行此测试，因为我认为模拟是最佳选择，我在寻找一些解决方案，但没有一个对我有用，您能帮助我了解如何解决此测试吗？
