[英]Mocking Azure BlobItem - C# unit test
I have some unit tests where I want to mock the Azure BlobItem
class (Azure.Storage.Blobs.Models).我有一些单元测试,我想在其中模拟 Azure
BlobItem
class (Azure.Storage.Blobs.Models)。
Here is my test class I'm using.这是我正在使用的测试 class。 I want the
Values
getter to return a list with a mock BlobItem.我希望
Values
getter 返回一个带有模拟 BlobItem 的列表。 That is working.那是有效的。
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();
}
}
However when I do this, the Name
property on my mock BlobItem is always null.但是,当我这样做时,我的模拟 BlobItem 上的
Name
属性始终是 null。
I can try to set it up so that Name
would return a mocked value like so:我可以尝试设置它,以便
Name
会返回一个模拟值,如下所示:
var mock = new Mock<BlobItem>();
mock.SetupGet(x => x.Name).Returns("mock");
But then I get an error:但后来我得到一个错误:
Non-overridable members may not be used in setup/verification expressions.
I understand why this error is happening.我明白为什么会发生这个错误。 But I do not know what the solution is.
但我不知道解决方案是什么。
I want a mocked BlobItem to return a non-null Name
value.我想要一个模拟的 BlobItem 返回一个非空的
Name
值。 How can I achieve this?我怎样才能做到这一点?
Apparently there's a factory class called BlobsModelFactory
.显然有一个名为
BlobsModelFactory
。
You can mock a BlobItem with whatever name you want by calling:您可以通过调用以任何您想要的名称模拟 BlobItem:
var blob = BlobsModelFactory.BlobItem("mocked.mocked.mocked.mocked")
