Unity,Moq和NUnit - 在测试中未识别参数的控制器构造函数

Question

我对单元测试很新,所以如果这不是一个非常好的问题,我会道歉.

我有一个主要的Web项目,以及一个附带的NUnit测试库.我正在使用Unity将接口注入主项目中的控制器.例如:

    public class EquipmentController : Controller
{
    private readonly ILocationRepository locationContext = null;
    private readonly IRepository<EquipmentCategory> categoryContext = null;
    private readonly IEquipmentRepository equipmentContext = null;
    private readonly IRecordRepository recordContext = null;

    public EquipmentController(ILocationRepository locationRepo, IRepository<EquipmentCategory> categoryRepo, IEquipmentRepository equipmentRepo, IRecordRepository recordRepo)
    {
        this.locationContext = locationRepo;
        this.categoryContext = categoryRepo;
        this.equipmentContext = equipmentRepo;
        this.recordContext = recordRepo;
    }

Web应用程序本身实际上按预期工作.但是,我在尝试编写测试用例时遇到了问题.例如,在测试库中,我有以下内容:

using NUnit.Framework;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Practices.Unity.Mvc;
using Microsoft.Practices.Unity.ObjectBuilder;
using Microsoft.Practices.Unity.StaticFactory;
using Moq;
using ITEquipmentDatabase;
using ITEquipmentDatabase.Models;
using ITEquipmentDatabase.Controllers;

namespace ITEquipmentDatabase.Tests
{
    [TestFixture]
    public class EquipmentController
    {
        [Test]
        public void TestMethod()
        {
            var equipRepo = new Mock<IEquipmentRepository>();
            var categoryRepo = new Mock<IRepository<EquipmentCategory>>();
            var locationRepo = new Mock<ILocationRepository>();
            var recordRepo = new Mock<IRecordRepository>();

            EquipmentController controller = new EquipmentController(locationRepo.Object, categoryRepo.Object, equipRepo.Object, recordRepo.Object);



        }
    }
}

但是,我收到以下错误:

Error   1   'ITEquipmentDatabase.Tests.EquipmentController' does not contain a constructor that takes 4 arguments   C:\Users\Khandokar\Documents\Visual Studio 2013\Projects\IT Equipment Log\ITEquipmentDatabase.Tests\EquipmentController.cs  27  46  ITEquipmentDatabase.Tests

我在我的测试项目中引用了Unity,甚至添加了Bootstrapper.cs(不确定是否有必要,但我试图解决上述问题).我很确定我做错了什么,但我刚开始冒险进行单元测试并且遇到了一些困难.

谢谢你的建议.

您的测试类已命名EquipmentController,您的测试类也是如此.

将您的测试类重命名为EquipmentControllerTests或类似.

(错误消息是线索;请注意它指的是Tests.EquipmentController).
