1、Four short words sum up what has lifted most successful individuals above the crowd: a little bit more.-author-dateWindows-Mobile下猜数字游戏的TDD实现Windows Mobile下猜数字游戏的TDD实现Windows Mobile下猜数字游戏的TDD实现背景早上看了TDD by example (1) - 挑战，觉得有趣，实现一个Windows Mobile版本。很多年前我也有一台文曲星，也常常玩这个猜数字游戏，所以尝试在Windows Mobile下实现。方案N

2、ick Wang (懒人王)强调需要TDD，所以我的实现方案也是TDD。实现使用NUintLite测试代码需要使用NUintLite，NUintLite具体可以参考.NET Compact Framework下的单元测试。修改Main函数如下，把结果写到SD卡上。static void Main(string args) System.IO.TextWriter writer = new System.IO.StreamWriter(Storage CardTestResult.txt); new NUnitLite.Runner.TextUI(writer).Execute(args); w

3、riter.Close(); Application.Run(new MainForm(); 编写测试代码TDD，先写测试代码。测试代码的逻辑是按照TDD by example (1) - 挑战写的，在实际使用中根据功能需求编写。TestFixture class BingleTest private Bingle bingle; SetUp public void SetUp() bingle = new Bingle(); TearDown public void TearDown() Test public void BuildAnswersTest() bingle.BuildAnsw

4、ers(); Assert.True(bingle.Answers0 != bingle.Answers1 & bingle.Answers0 != bingle.Answers2 & bingle.Answers0 != bingle.Answers3 & bingle.Answers1 != bingle.Answers2 & bingle.Answers1 != bingle.Answers3 & bingle.Answers2 != bingle.Answers3); Test public void MatchTest() bingle.Answers = new int 1, 2,

5、 3, 4 ; int a; int b; int num; /1 5 6 7 1A0B num = new int 1, 5, 6, 7 ; bingle.Match(num, out a, out b); Assert.That(a, Is.EqualTo(1); Assert.That(b, Is.EqualTo(0); /2 4 7 8 0A2B num = new int 2, 4, 7, 8 ; bingle.Match(num, out a, out b); Assert.That(a, Is.EqualTo(0); Assert.That(b, Is.EqualTo(2); /

8、hTest2() int a; int b; int num; /1 1 2 3 num = new int 1, 1, 2, 3 ; bingle.Match(num, out a, out b); /1 2 num = new int 1, 2 ; bingle.Match(num, out a, out b); 我把对Match测试的代码写在一起，我喜欢一个Test函数对应一个功能函数。而把异常处理分开出来写了，怕前面的测试抛出异常，导致测试通过了。功能代码功能代码的目的就是通过所以单元测试。public class Bingle public int Answers set; get;

9、 private int attemptTimes; public int AttemptTimes get return attemptTimes; public Bingle() Answers = new int4; public void BuildAnswers() Random r = new Random(); while(true) int i = r.Next(9999); Answers0 = i / 1000; Answers1 = i % 1000 / 100; Answers2 = i % 100 / 10; Answers3 = i % 10; if (Answer

10、s0 != Answers1 & Answers0 != Answers2 & Answers0 != Answers3 & Answers1 != Answers2 & Answers1 != Answers3 & Answers2 != Answers3) return; public bool Match(int attemptNum, out int bingle, out int match) bingle = 0; match = 0; if (attemptNum.Length != 4) throw new ArgumentException(Should be 4 digit

11、s.); if(!(attemptNum0 != attemptNum1 & attemptNum0 != attemptNum2 & attemptNum0 != attemptNum3 & attemptNum1 != attemptNum2 & attemptNum1 != attemptNum3 & attemptNum2 != attemptNum3) throw new ArgumentException(Should be non repeating 4 digits.); +attemptTimes; for(int i=0; i4; +i) if (attemptNumi =

12、 Answersi) +bingle; else for (int j = 0; j 4; +j) if (attemptNumi = Answersj) +match; return (bingle = 4); 单元测试结果如果通过所有单元测试，说明功能代码编写完毕，每次修改都有run单元测试。NUnitLite version 0.2.0Copyright 2007, Charlie PooleRuntime Environment - OS Version: Microsoft Windows CE 5.2.21234 .NET Version: 2.0.7045.0/Files/procoder/Bingle.rar3 Tests : 0 Errors, 0 Failures, 0 Not RunUI 处理功能代码写完以后，可以写UI了，具体UI代码见源代码，下面是执行效果。源代码：Bingle.rar环境： VS 2008 + WM 6 professional SDK + NUnitLite-
