Question

我想测试我的代码是否正常工作，所以我正在为它编写一些单元测试。

我想检查何时和我的列表中具有相同值的项目再次添加它应该返回false。

我真的不明白如何设置它。我希望有些人可以帮助我。在我的代码下面

GuestResponseRepository

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using PartyInvites.Abstract;

namespace PartyInvites.Models
{
    public class GuestResponseRepository : IRepository

    {
        private static List<GuestResponse> responses = new List<GuestResponse>();

        IEnumerable<GuestResponse> IRepository.GetAllResponses()
        {
            return responses;
        }

        bool IRepository.AddResponse(GuestResponse response)
        {
            if (responses.Any(x => x.Email == response.Email)) //here
            {
                if (responses.Any(x => x.WillAttend == response.WillAttend)) //here
                {
                    return false;
                }

                var attend = responses.First(x => x.Email == response.Email && x.WillAttend != response.WillAttend);
                attend.WillAttend = response.WillAttend;
                return true;
            }

            responses.Add(response);
            return true;
        }
    }
}

我的界面与GuestResponseRepository

进行通信

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.Threading.Tasks;
 using PartyInvites.Models;

namespace PartyInvites.Abstract
{
    public interface IRepository
    {
        IEnumerable<GuestResponse> GetAllResponses();
        bool AddResponse(GuestResponse response);
    }
}

我家用控制器的一部分

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using PartyInvites.Models;
using PartyInvites.Abstract;

namespace PartyInvites.Controllers {
    public class HomeController : Controller {
        private IRepository repository;

        public HomeController(IRepository iRepository)
        {
            this.repository = iRepository;
        }


        [HttpGet]
        public ViewResult RsvpForm() {
            return View();
        }

        [HttpPost]
        public ViewResult RsvpForm(GuestResponse guestResponse) {
            if (ModelState.IsValid) {

                bool result = repository.AddResponse(guestResponse);
                ViewBag.Response = result;

                repository.AddResponse(guestResponse);                
                return View("Thanks", guestResponse);
            }
            else
            {
                // there is a validation error
                return View();
            }
        }
    }
}

我的UnitTest到目前为止我得到了什么

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using PartyInvites.Abstract;
using PartyInvites.Controllers;
using PartyInvites.Models;
using Moq;

namespace Aanmelden
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void FirstResponse()
        {
            //Arange
            Mock<IRepository> mock = new Mock<IRepository>();
            mock.Setup(m => m.AddResponse()).Returns(new GuestResponse[] {
            new GuestResponse {Name = "Valheru", Email = "valheru@hotmail.com", Phone = "12345678", WillAttend = true}
            });

            HomeController controller = new HomeController(mock.Object);
            //Act
            new GuestResponse
            {
                Name = "Valheru",
                Email = "valheru@hotmail.com",
                Phone = "12345678",
                WillAttend = true
            };

            //Assert
            if viewbag.response = result == false test succeeded

        }
    }
}

出于某种原因mock.Setup(m => m.**AddResponse**()).Returns(new GuestResponse[] {... “AddResponse”是正确的说Visual Studio - ＆gt;

没有任何论据符合所要求的形式 IRepository.AddResponse（GuestReponse）的参数'response'

我也不确定我的Act代码，我完全失去了Assert部分。我希望有人可以帮助我！

Answer 1

您应该It.IsAny<GuestResponse>()作为参数，以匹配您的界面的签名

    Mock<IRepository> mock = new Mock<IRepository>();
    mock.Setup(m => m.AddResponse(It.IsAny<GuestResponse>())).Returns(true);

Answer 2

基于

我想检查列表中具有相同值的项目何时添加再次它应该返回false。

您实际上应该测试GuestResponseRepository实现本身，而不是控制器。

[TestMethod]
public void Duplicate_Added_Should_Return_False {
    //Arrange
    var sut = new GuestResponseRepository();
    var model = new GuestResponse
    {
        Name = "Valheru",
        Email = "valheru@hotmail.com",
        Phone = "12345678",
        WillAttend = true
    };

    sut.AddResponse(model);

    var expected = false;

    //Act
    var actual = sut.AddResponse(model);

    //Assert
    Assert.AreEqual(expected, actual);
}

UnitTest将项添加到列表并检查是否存在
