如何模拟Azure队列存储进行单元测试？

Question

我想模拟 QueueMessage 进行单元测试，但我找不到任何库来模拟

    public  async Task<QueueMessage[]> ReceiveMessagesAsync(QueueClient queue)
       {
     
        QueueProperties properties = queue.GetProperties();

        // Retrieve the cached approximate message count.
        int cachedMessagesCount = properties.ApproximateMessagesCount;
        QueueMessage[] queueMessages =new QueueMessage[cachedMessagesCount];

        int num = cachedMessagesCount / 32;

        for (int i = 0; i < num + 1; i++)
        {
         var  messages = await queue.ReceiveMessagesAsync(maxMessages: 32);
         messages.Value.CopyTo(queueMessages,i*32);
        }
        return queueMessages;
    }

队列模型的构造函数是内部的，但您可以使用QueuesModelFactory创建对象，它提供了用于模拟的实用程序。

QueueMessage queueMsg = QueuesModelFactory.QueueMessage(
    messageId: "id2", 
    popReceipt: "pr2", 
    body: JsonConvert.SerializeObject("Test"), 
    dequeueCount: 1, 
    insertedOn: DateTimeOffset.UtcNow);

 var metadata = new Dictionary<string, string> { { "key", "value" }, };
 int messageCount = 5;
 QueueProperties queueProp = QueuesModelFactory.QueueProperties(metadata, messageCount);
