Moq - 如何从方法返回模拟对象？

Question

我是Moq的新手,并希望不仅在单元测试中使用它,我似乎主要是在代码中获取它.

鉴于此实体:

 namespace TestBed.Domain.Entities
 {
    public class Person
    {
        public string LastName { get; set; }
        public string FirstName { get; set; }
        public string PhoneNumber { get; set; }
        public string JobTitle { get; set; }
    }
 }

这个抽象的存储库:

using TestBed.Domain.Entities;

namespace TestBed.Domain.Abstract
{
    public interface IPersonRepository
    {
        Person GetPerson();
    }
}

我想使用Moq填充一个虚拟人(!)并将该填充的"对象"传递给Repository方法.我该怎么做呢？

using TestBed.Domain.Abstract;
using TestBed.Domain.Entities;
using Moq;

namespace TestBed.Domain.Concrete
{
    public class MockPersonReqpository
    {
        Person GetPerson()
        {
            Mock<IPersonRepository> mock = new Mock<IPersonRepository>();
            mock.Setup(m => m.GetPerson()).Returns(new Person()
                                                       {
                                                           FirstName = "Joe",
                                                           LastName = "Smith",
                                                           PhoneNumber = "555-555-5555"
                                                       });
            return mock.Object // NO
        }

    }
}

根据您对@ Daniel的回答的评论,您似乎只需要模拟存储库本身.您仍然希望返回一个正确的Person对象,您只是不关心存储库实际上是否为了您的测试而检索该人.

除了单元测试之外,我也不理解你在其他地方使用Moq的评论.Moq的全部意义在于你可以伪造一个实际的对象用于测试目的(可能更好地说,但这是要点).

由于我不知道你要测试的是什么,我将给出一个简单的例子:

[TestMethod]
public void WhenValidRequest_ThenReturnSuccess()
{
    Mock<IPersonRepository> personRepository = new Mock<IPersonRepository>();
    personRepository.Setup(r => r.GetPerson()).Returns(
        new Person() 
        { 
            FirstName = "Joe",
            LastName = "Smith"
            /*...*/
        });

    Foo objectUnderTest = new Foo(personRepository.Object);

    bool result = objectUnderTest.MakeRequest(); 
    // Call method using the person repository that you want to test.
    // You don't actually care how the repository works, you just want to return a success 
    // boolean when a person exists for that request.

    Assert.IsTrue(result);
}
