CosmosDB错误429单元测试：请求率很高

Question

我通过添加Request rate is large变量修复了CosmosDB中的new ConnectionPolicy()错误：

var client = new DocumentClient(new Uri(endpointUri), primaryKey, new ConnectionPolicy()
                    {
                        MaxConnectionLimit = 100,
                        ConnectionMode = ConnectionMode.Direct,
                        ConnectionProtocol = Protocol.Tcp,
                        RetryOptions = new RetryOptions() { MaxRetryAttemptsOnThrottledRequests = 3, MaxRetryWaitTimeInSeconds = 60 }
                    });

但是我想知道我们如何进行单元测试以确保它真正起作用？

我正在考虑模拟DocumentClient并进行繁重的设置。但是我不确定语法应该是什么样。

以下是快乐案例的样本单元测试代码：

 var mockDocumentQuery = new Mock<IFakeDocumentQuery<BookModel>>();

            mockDocumentQuery
                .SetupSequence(_ => _.HasMoreResults)
                .Returns(true)
                .Returns(false);

            mockDocumentQuery
                .Setup(_ => _.ExecuteNextAsync<BookModel>(It.IsAny<CancellationToken>()))
                .ReturnsAsync(response);

            var provider = new Mock<IQueryProvider>();
            provider
                .Setup(_ => _.CreateQuery<BookModel>(It.IsAny<Expression>()))
                .Returns(mockDocumentQuery.Object);

            mockDocumentQuery.As<IQueryable<BookModel>>().Setup(x => x.Provider).Returns(provider.Object);
            mockDocumentQuery.As<IQueryable<BookModel>>().Setup(x => x.Expression).Returns(dataSource.Expression);
            mockDocumentQuery.As<IQueryable<BookModel>>().Setup(x => x.ElementType).Returns(dataSource.ElementType);
            mockDocumentQuery.As<IQueryable<BookModel>>().Setup(x => x.GetEnumerator()).Returns(() => dataSource.GetEnumerator());

            var client = new Mock<IDocumentClient>();

            client.Setup(_ => _.CreateDocumentQuery<BookModel>(It.IsAny<Uri>(), It.IsAny<FeedOptions>()))
                  .Returns(mockDocumentQuery.Object);

在代码的最后一行中，如何设置繁重的DocumentClient？
