使用Moq模拟参数的属性更改

我正在使用Moq来模拟我的Repository层,所以我可以进行单元测试.

我的存储库层插入方法在发生成功的数据库插入时更新我的​​实体的Id属性.

在调用Insert方法时,如何配置moq以更新实体的Id属性？

存储库代码: -

void IAccountRepository.InsertAccount(AccountEntity account);

单元测试:-

[TestInitialize()]
public void MyTestInitialize() 
{
    accountRepository = new Mock();
    contactRepository = new Mock();
    contractRepository = new Mock();
    planRepository = new Mock();
    generator = new Mock();

    service = new ContractService(contractRepository.Object, accountRepository.Object, 
                    planRepository.Object, contactRepository.Object, generator.Object);   
}


[TestMethod]
public void SubmitNewContractTest()
{
    // Setup Mock Objects
    planRepository
        .Expect(p => p.GetPlan(1))
        .Returns(new PlanEntity() { Id = 1 });

    generator
        .Expect(p => p.GenerateAccountNumber())
        .Returns("AC0001");

    // Not sure what to do here? 
    // How to mock updating the Id field for Inserts?
    //                                                 
    // Creates a correctly populated NewContractRequest instance
    NewContractRequest request = CreateNewContractRequestFullyPopulated();

    NewContractResponse response = service.SubmitNewContract(request);
    Assert.IsTrue(response.IsSuccessful);
}

ContractService类(WCF服务合同)的实现片段.

AccountEntity account = new AccountEntity()
{
    AccountName = request.Contact.Name,
    AccountNumber = accountNumber,
    BillingMethod = BillingMethod.CreditCard,
    IsInvoiceRoot = true,
    BillingAddressType = BillingAddressType.Postal,
    ContactId = request.Contact.Id.Value
};

accountRepository.InsertAccount(account);
if (account.Id == null)
{
    // ERROR
}

如果这些信息可能有点缺乏,我深表歉意.我今天才开始学习moq和模拟框架.AC

您可以使用Callback方法来模拟副作用.就像是:

accountRepository
    .Expect(r => r.InsertAccount(account))
    .Callback(() => account.ID = 1);

这是未经测试的,但它是沿着正确的路线.
