如何在 c# 中模拟此 EmailCreation 以进行单元测试

Question

Hi I´m trying to test a class of my project that generate a SendResponse with an Email template

this is my code

            await Email.Create()
                .To(request.Parcel.CustomerEmail)
                .Subject(emailSubject)
                .UsingTemplateFromEmbedded(emailTemplate, new ParcelReceivedEmailModel()
                {
                    Parcel =  request.Parcel,
                    Shop = shopInfo
                }, GetType().Assembly)
                .SendAsync(cancellationToken);

in the xunit test class i´m mocking IFluentEmailFactory to test that, this is my mock code:

            _mockFluentEmailFactory.Setup(x => x.Create()
            .To(It.IsAny<string>())
            .Subject(It.IsAny<string>())
            .UsingTemplateFromEmbedded(It.IsAny<string>(), It.IsAny<string>(),
              It.IsAny<string>(),It.IsAny<string>())
            .SendAsync(It.IsAny<CancellationToken>()))
            .ReturnsAsync(fakeSendResponse);

but i get allways a nullException and I don´t know why, can someone help me? im new doing test and it seems no to be so difficult

I search information in xunit

Solved:

.UsingTemplateFromEmbedded(It.IsAny<string>(), It.IsAny<ParcelReceivedEmailModel>(), It.IsAny<Assembly>(), It.IsAny<bool>())
