检查属性是否已设置 - 使用Moq

Question

我是Moq的新手,一般都在测试,所以这是我的noobish Q.如何测试请求中的Status属性是否已使用Moq设置？

public class DudeManager
{
        private readonly IDRepository _repo;

        public DManager(IDRepository repo)
        {
            _repo = repo;
        }

        public void Create(Request r)
        {
            r.Status = Status.Submitted;
            _repo.AddRequest(r);
        }
}

有没有比以下更好的方法？也许使用VerifySet？

        [TestMethod]
        public void AddingNewRequestSetsStatusToSubmitted()
        {
            //Arrange
            var mock = new Mock<IDRepository>();
            var mockRequest = new Mock<Request>();
            var dManager = new DManager(mock.Object);

            //Act
            dManager.Create(mockRequest.Object);

            //Assert
            Assert.AreEqual(Status.Submitted, mockRequest.Object.Status);
        }

编辑:这是我在所有有用的建议后最终使用的方法:

//Arrange
var request = new Request();
var mock = new Mock<IDRepository>();
var dManager = new DManager(mock.Object);
mock.Setup(x => x.AddRequest(It.IsAny<Request>()));

//Act
dManager.QueueNewRequest(request);

//Assert
Assert.AreEqual(RequestStatus.Submitted, request.Status);

这种方法似乎对我而言.有人怎么想？

Answer 1

我认为VerifySet是正确的方法.它看起来像这样:

//Arrange
var mock = new Mock<IDRepository>();
var mockRequest = new Mock<Request>();
// TODO: set some expectations here

var dManager = new DManager(mock.Object);

//Act
dManager.Create(mockRequest.Object);

//Assert
mockRequest.VerifySet(x => x.Status = Status.Submitted);

我相信你的情况,它会爆炸,因为你还没有设置你的Request mock来处理Status上的set操作.

一个简单的方法是使用SetupAllProperties,如下所示:

//Arrange
var mock = new Mock<IDRepository>();
var mockRequest = new Mock<Request>();
mockRequest.SetupAllProperties();

我认为您应该默认使用严格的行为,然后您可以通过一次调用进行验证.它还使您更明确地编写测试.

[TestMethod]
public void AddingNewRequestSetsStatusToSubmitted()
{
    //Arrange
    var mock = new Mock<IDRepository>(MockBehavior.Strict);
    var mockRequest = new Mock<Request>(MockBehavior.Strict);
    var dManager = new DManager(mock.Object);

    mockRequest.SetupSet(item => item.Status = It.IsAny<StatusType>())
               .Verifiable();

    //Act
    dManager.Create(mockRequest.Object);

    //Assert
    Assert.AreEqual(mockRequest.Object.Status, Status.Submitted);
    mock.VerifyAll();
    mockRequest.VerifyAll();
}
