What is the best way to mock Batch request?

[kenakamu]

Batch cannot be mocked as easy as other methods. What is the recommended way to mock Batch request so that I can write unit test?

Hey @kenakamu,

For starters you could always checkout the tests here.

You could also use checkout the tests for BatchResponseContent and BatchRequestContent here

Thanks. I am having following code in my project and want to create uint test around it.

graphServiceClient.Batch.Request().PostAsync(batchRequestContent)

I can easily mock normal ones, but not Batch. I do mock like below for other request.

mockedGraphServiceClient.Setup(x => x.Users[It.IsAny<string>()]
                .Request()
                .Select(It.IsAny<Expression<Func<Microsoft.Graph.User, object>>>())
                .GetAsync(It.IsAny<CancellationToken>()))
                .ReturnsAsync(new Microsoft.Graph.User() { Id = userId.ToString(), BusinessPhones = new List<string>() });

So ideally, if I can simply mock Batch request same as above, that would be ideal. At the moment, I cannot setup Batch itself as it's not virtual method.

By the way, this is what I am doing at the moment. https://dev.to/kenakamu/c-how-to-unit-test-graph-sdk-batch-request-38j2
