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; }
private int attemptTimes;
public int AttemptTimes
{
get
{
return attemptTimes;
}
}
public Bingle()
{
Answers = new int[4];
}
public void BuildAnswers()
{
Random r = new Random();
while(true)
{
int i = r.Next(9999);
Answers[0] = i / 1000;
Answers[1] = i % 1000 / 100;
Answers[2] = i % 100 / 10;
Answers[3] = i % 10;
if (Answers[0] != Answers[1]
&& Answers[0] != Answers[2]
&& Answers[0] != Answers[3]
&& Answers[1] != Answers[2]
&& Answers[1] != Answers[3]
&& Answers[2] != Answers[3])
{
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 digits.");
}
if(!(attemptNum[0] != attemptNum[1]
&& attemptNum[0] != attemptNum[2]
&& attemptNum[0] != attemptNum[3]
&& attemptNum[1] != attemptNum[2]
&& attemptNum[1] != attemptNum[3]
&& attemptNum[2] != attemptNum[3]))
{
throw new ArgumentException("Should be non repeating 4 digits.");
}
++attemptTimes;
for(int i=0; i<4; ++i)
{
if (attemptNum[i] == Answers[i])
{
++bingle;
}
else
{
for (int j = 0; j < 4; ++j)
{
if (attemptNum[i] == Answers[j])
{
++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。

UI 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。
