Question

关于TDD，我正在阅读本教程http://blogs.telerik.com/justteam/posts/13-10-25/30-days-of-tdd-day-17-specifying-order-of-execution-in-mocks。我试图将一个JustMock语句改编为Moq。

enter code here [Test]
    public void testname()
    {
        var customerId = Guid.NewGuid();
        var customerToReturn = new Customer { Id = customerId};

        //JustCode
        Mock _customerService = Mock.Create<ICustomerService>();
        Mock.Arrange(() => _customerService.GetCustomer(customerId)).Returns(customer).OccursOnce();


        //Moq
        Mock<ICustomerService> _customerService = new Mock <ICustomerService>();
        _customerService.Setup(os => os.GetCustomer(customerId)).Returns(customerToReturn);
        _customerService.VerifyAll();
    }

当测试运行时，我得到了这个例外：

Moq.MockVerificationException : The following setups were not matched:ICustomerService os => os.GetCustomer(a1a0d25c-e14a-4c68-ade9-bc3d7dd5c2bc)

当我将.VerifyAll（）更改为.Verify（）时，测试通过，但我不确定这是否正确。

问题：适应此代码的正确方法是什么？ .VerifyAll（）与.OccursOnce（）不相似吗？

您似乎错过了设置上的.verifiable。你也可以避免任何可验证的，只需在最后使用mock.Verify。您还必须调用模拟的实例，以便进行可验证的工作。 https://github.com/Moq/moq4/wiki/Quickstart

请参阅下面的两种方法。

    [Test]
    public void testname()
    {
        var customerId = Guid.NewGuid();
        var customerToReturn = new Customer { Id = customerId};

        //Moq
        var _customerService = new Mock <ICustomerService>();
        _customerService.Setup(os => os.GetCustomer(customerId)).Returns(customerToReturn).Verifiable();

        var cust = _customerService.Object.GetCustomer(customerId);

        _customerService.VerifyAll();
    }


    [Test]
    public void testname1()
    {
        var customerId = Guid.NewGuid();
        var customerToReturn = new Customer { Id = customerId };

        //Moq
        var _customerService = new Mock<ICustomerService>();
        _customerService.Setup(os => os.GetCustomer(customerId)).Returns(customerToReturn);

        var cust = _customerService.Object.GetCustomer(customerId);

        _customerService.Verify(x => x.GetCustomer(customerId));
    }

以下设置不匹配 - 将JustMock转换为Moq
