测试驱动开发TDD(3)

　　实现GameManager让测试通过。
public class GameManager
{
private readonly IGuesser guesser;
public bool IsGameOver { get; private set; }
private const int MAX_TIMES = 6;
private int times;
public GameManager(IGuesser guesser)
{
this.guesser = guesser;
}
public void Guess(string input)
{
times++;
IsGameOver = times == MAX_TIMES;
guesser.Guess(input);
}
}

    ok
　　猜测数字
　　输入验证
　　生成答案
　　输入次数
　　输出猜测结果
　　输入猜测结果。这里包含一个猜对的情况下应该返回"you win"并且Gameover。其他输入返回的结果，在Guesser和validator中已经Cover了。挑几个来测试一下输入输出。
