NUnit + VS2010 简单入门

一、环境准备 

1. NUnit 2.6.3

下载地址：https://launchpadlibrarian.net/153448476/NUnit-2.6.3.msi

2. VS2010

二、安装 NUnit（略）

三、编写代码

项目结构

AlgLib 代码

Alg.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace AlgLib
{
    /// <summary>
    /// 算法库，待测试对象
    /// </summary>
    public class Alg
    {
        public int Add(int a, int b)
        {
            return (a + b);
        }
    }
}

Singleton.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace AlgLib
{
    /// <summary>
    /// 单例类，待测试对象
    /// </summary>
    public sealed class Singleton
    {
        private static readonly Singleton _instance = new Singleton();
        private Guid _guid;

        private Singleton()
        {
            _guid = Guid.NewGuid();
        }


        public static Singleton SingletonInstance
        {
            get { return _instance; }
        }

        public Guid InstanceGuid
        {
            get { return _guid; }
        }
    }
}

AlgLibTest 单元测试项目代码

AlgTest.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using NUnit.Framework;
using AlgLib;

namespace AlgLibTest
{
    /// <summary>
    /// 算法库单元测试
    /// </summary>
    [TestFixture]
    public class AlgTest
    {
        [Test]
        public void TestAdd()
        {
            Alg alg = new Alg();
            var result = alg.Add(1, 2);
            Assert.AreEqual(2, result); // NUnit报错
        }
    }
}

SingletonTest.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using NUnit.Framework;
using AlgLib;

namespace AlgLibTest
{
    [TestFixture]
    public class SingletonTest
    {
        [Test]
        public void TestSingleton()
        {
            var instanceA = Singleton.SingletonInstance;
            var instanceB = Singleton.SingletonInstance;

            Assert.AreEqual(instanceA.InstanceGuid, instanceB.InstanceGuid);
        }
    }
}

编译。。。

四、用NUnit 进行单元测试

运行结果

附加nuint.exe 进程还能在错误的时候进行代码调试
