当 UnitTest 调用该方法时，起订量设置返回 null object

Question

测试设置

当测试命中 controller 里面的方法时，Mock 给出 null object

我的控制器的构造函数有两个我模拟的依赖项。 在为 CheckOut 运行测试时，它在结果中给出 null object。 我在 Model 对象和业务之间使用 AutoMapper 到 map

[Fact]
public void CheckOutSomethingsTest()
{
    Mock<ICheckoutService> checkoutServiceMock = new Mock<ICheckoutService>();
    Mock<IMapper> mapperMock = new Mock<IMapper>();

    checkoutServiceMock.Setup(c => c.CheckoutSomethings(new CheckOutSomethingsInput
    {
        SecretKey = "SecureKey",
        UserId = 100,
        SomethingIds = new List<int> { 10001, 1002, 1003 }
    }))
    .Returns<List<CheckedOutSomething>>((o) => new List<CheckedOutSomething>
    {
            new CheckedOutSomething { Id = 10001, Remarks = "Success" },
            new CheckedOutSomething  { Id = 10002, Remarks = "Success" }
    });

    var configuration = new MapperConfiguration(cfg =>
    {
        cfg.AddSomething(new AutoMapperBusinessToEntitiesSomething());
        cfg.AddSomething(new AutoMapperModelsToBusinessSomething());
    });

    var mapper = new Mapper(configuration);
    var controller = new SomethingsController(checkoutServiceMock.Object, mapper);

    var result = controller.CheckOut(
        new CheckOutSomethingInputModel 
        { 
              UserId = 100, 
              SomethingIds = new List<int> { 10001, 10002, 10003 } 
        });

    Assert.IsType<OkObjectResult>(result.Result);
    Assert.Equal(2, result.Value.Count);
}

服务构造器

public ProfilesController(ICheckoutService checkoutService, IMapper mapper)
{
    this.checkoutService = checkoutService;
    this.mapper = mapper;            
}

方法

[HttpPost]
[Route("checkout")]
public ActionResult<List<CheckedOutSomethingModel>> 
        CheckOut([FromBody] CheckOutSomethingInputModel checkoutInput)
{       
    if (!ModelState.IsValid)
    {
        return BadRequest(ModelState);
    } 

    var input = mapper.Map<CheckOutSomethingsInput>(checkoutInput);
    var output = mapper.Map<List<CheckedOutSomethingModel>> 
    (checkoutService.CheckoutSomethings(input));
    return Ok(output);
}

我无法弄清楚我做错了什么

@Fabio 非常感谢是这样的吗

checkoutServiceMock.Setup(c => c.CheckoutSomethings(It.IsAny<CheckOutSomethingsInput>()))
                .Returns(new List<CheckedOutSomething>
            {
                new CheckedOutSomething { Id = 10001, Remarks = "Success" },
                new CheckedOutSomething { Id = 10002, Remarks = "Success" }
            });

我确实做到了，而且成功了，再次感谢
