Mocking Blobclient.DownloadContentAsync()

[sarwary]

Hello, am I mocking the method below correctly coz, when called its not returning the result:

var blobContent = new BinaryData("this is test data");
var downloadResult = BlobsModelFactory.BlobDownloadResult(content: blobContent);
var response = Response.FromValue(downloadResult, blobContainerClientResponseMock.Object);

mockBlobClientTrue.Setup(client => client.DownloadContentAsync(default)).ReturnsAsync(response);

the reslut object of the task returned form this method is null.

I am using it like this in my code and it works:

var response = await blobClient.DownloadContentAsync();
if (!response.HasValue || response.GetRawResponse().IsError) (....)

This is how I mocked:

 var mockResponse = new Mock<Response>();
 var mockValue = BlobsModelFactory.BlobDownloadResult(new BinaryData("some data"), default);
_blobClient.Setup(x => x.DownloadContentAsync(default)).ReturnsAsync(Response.FromValue(mockValue, mockResponse.Object));

If I pass 'default' or 'It.IsAny()' inside my mocking the result is always null.

Now it is updated to FakeItEasy. However if you follow the repo and see the old commits you will still be able to find which is using MOQ
