嘿,伙计们,

我遇到了一个问题,我敢肯定,与嘲弄参考参数必须是显而易见的,但作为一个新的框架,我只是不能工作

我有以下存储库方法:

public int SaveCard(int userId, CardPaymentMethodDto
cardPaymentMethodDto)
{
        int? cardId = 0;
        try
        {
                int result = this.dataContext.usp_PaymentMethod_Card_Insert(userId,
                                cardPaymentMethodDto.UserAccountReference,
                                cardPaymentMethodDto.EncryptedCardNumber,
                                cardPaymentMethodDto.BinRange,
                                cardPaymentMethodDto.LastFourDigits,
                                cardPaymentMethodDto.ExpiryMonth,
                                cardPaymentMethodDto.ExpiryYear,
                                cardPaymentMethodDto.IssueNumber,
                                cardPaymentMethodDto.IssuingBank,
                                cardPaymentMethodDto.IssuingCountry,
                                cardPaymentMethodDto.Scheme,
                                cardPaymentMethodDto.StartMonth,
                                cardPaymentMethodDto.StartYear,
                                cardPaymentMethodDto.BillingAddress.House,
                                cardPaymentMethodDto.BillingAddress.SubPremises,
                                cardPaymentMethodDto.BillingAddress.Street,
                                cardPaymentMethodDto.BillingAddress.Town,
                                cardPaymentMethodDto.BillingAddress.County,
                                cardPaymentMethodDto.BillingAddress.Postcode,
                                cardPaymentMethodDto.BillingAddress.Country,
                                cardPaymentMethodDto.DateRegistered,
                                ref cardId);

                if (result <= 0)
                {
                        CompanySystemSqlException tex = new
CompanySystemSqlException("Database communications error");
                        tex.Data.Add("UserId", userId);
                        tex.Data.Add("PaymentMethod", cardPaymentMethodDto.ToString());
                        Logger.LogException("SaveCard: result <= 0", tex);
                        throw tex;
                }
        }
        catch (DbException ex)
        {
                CompanySystemSqlException tex = new
CompanySystemSqlException("Database communications error", ex);
                tex.Data.Add("UserId", userId);
                tex.Data.Add("PaymentMethod", cardPaymentMethodDto.ToString());
                Logger.LogException("SaveCard: DbException", tex);
                throw tex;
        }

        return cardId ?? 0;

}

[Test]
public void SaveCard_ValidData_ShouldReturnValidCardId()
{
        int cardId;
        int? refCardId = 0;
        dataContext.DefaultValue = DefaultValue.Mock;
        dataContext.Setup( x =>
x.usp_PaymentMethod_Card_Insert(It.IsAny<int>(), It.IsAny<string>(),
It.IsAny<string>(), It.IsAny<string>(),
                It.IsAny<string>(), It.IsAny<string>(), It.IsAny<string>(),
It.IsAny<int>(), It.IsAny<string>(), It.IsAny<string>(),
                It.IsAny<string>(), It.IsAny<string>(), It.IsAny<string>(),
It.IsAny<string>(), It.IsAny<string>(), It.IsAny<string>(),
                It.IsAny<string>(), It.IsAny<string>(), It.IsAny<string>(),
It.IsAny<string>(), It.IsAny<DateTime>(), ref refCardId)).Returns(1);

        cardId = paymentRepository.SaveCard(1, new CardPaymentMethodDto
{ BillingAddress = new AddressDto { Country = "", County = "", House =
"", Postcode = "", Street = "", SubPremises = "", Town = ""},
                                                                                                        BinRange = "", Cv2 = 123,
                                                                                                        DateRegistered = DateTime.Now, EncryptedCardNumber =
"jumble",
                                                                                                        ExpiryMonth = "02", ExpiryYear = "2030", Id = 1,
IssueNumber = 1, IssuingBank = "", IssuingCountry = "",
                                                                                                        LastFourDigits = "", LastUsed = DateTime.MinValue, Scheme
= "", StartMonth = "", StartYear = "",
                                                                                                        UserAccountReference = ""});

        Assert.That(cardId, Is.EqualTo(1));

}

测试,或者我无法设置预期结果,但refcard<> repository cardId变量,因此它显然失败了(由第一种方法返回为零)。

谢谢你的帮助, 干杯, 特里

从moq4.8开始(它还没有发布,但是有一个预发布版本),你可以匹配 ref It.Ref<T>.IsAny :

dataContext.Setup(x => x.usp_PaymentMethod_Card_Insert(
                           It.IsAny<int>(),
                           It.IsAny<string>(),
                           ...
                           It.IsAny<DateTime>(),
                           ref It.Ref<int?>.IsAny))
           .Returns(1);

我不太确定我是否理解这个问题,但您在测试中已将0分配给refcardd。

int? refCardId = 0;

你的mock不会改变这个值,因为它不能。你的mock只是一个代理,它完全按照你在安装方法中告诉它的做。在这种情况下,调用Mock时将返回1。它与refcard没有任何关系。

请记住,sut是paymentRepository及其SaveCard方法—mock只用于测试sut,而不依赖于dataContext。
