模拟 Azure BlobItem - C# 单元测试 [英] Mocking Azure BlobItem - C# unit test

问题描述

我有一些单元测试，我想模拟 Azure BlobItem 类 (Azure.Storage.Blobs.Models).

I have some unit tests where I want to mock the Azure BlobItem class (Azure.Storage.Blobs.Models).

这是我正在使用的测试类.我希望 Values 获取器返回一个带有模拟 BlobItem 的列表.这是有效的.

Here is my test class I'm using. I want the Values getter to return a list with a mock BlobItem. That is working.

public class TestPage : Page<BlobItem>
{
    public override IReadOnlyList<BlobItem> Values
    {
        get
        {
            return new List<BlobItem>() { new Mock<BlobItem>().Object };
        }
    }

    public override string ContinuationToken => throw new NotImplementedException();

    public override Response GetRawResponse()
    {
        throw new NotImplementedException();
    }
}

但是，当我这样做时，我的模拟 BlobItem 上的 Name 属性始终为空.

However when I do this, the Name property on my mock BlobItem is always null.

我可以尝试设置它，以便 Name 返回一个模拟值，如下所示:

I can try to set it up so that Name would return a mocked value like so:

var mock = new Mock<BlobItem>();
mock.SetupGet(x => x.Name).Returns("mock");

但是我得到一个错误:

Non-overridable members may not be used in setup/verification expressions.

我明白为什么会发生这个错误.但我不知道解决方案是什么.

I understand why this error is happening. But I do not know what the solution is.

我想要一个模拟的 BlobItem 返回一个非空的 Name 值.我怎样才能做到这一点?

I want a mocked BlobItem to return a non-null Name value. How can I achieve this?

推荐答案

显然有一个名为 BlobsModelFactory 的工厂类.

Apparently there's a factory class called BlobsModelFactory.

您可以通过调用以下任何名称来模拟 BlobItem:

You can mock a BlobItem with whatever name you want by calling:

var blob = BlobsModelFactory.BlobItem("mocked.mocked.mocked.mocked")
