需求分析：

1.整数加减乘除的测试；

2.分数加减乘除的测试；

3.最大公约数测试；

4.判断真分数测试；

计算模块：

public int gcd(int a, int b)//公约数
        {
            if (a == 0)
            {
                return b;
            }
           else if (b == 0)
            {
                return a;
            }
            else
            {
                return gcd(b % a, a);
            }
        }
        public int Calculate(int type, int op1, int op2)//整数四则运算
        {
            int result = 0;
            if (type == 1)
            {
                result = op1 + op2;
            }
            if (type == 2)
            {
                result = op1 - op2;
            }
            if (type == 3)
            {
                result = op1 * op2;
            }
            if (type == 4)
            {
                result = op1 / op2;
            }
            return result;
        }
        public string CalculateFengsu(int up1, int down1, int up2, int down2, int type)//分数四则运算
        {
            string result = "";
            if (type == 1)
            {
                up1 = (up1 * down2 + up2 * down1);
                down1 = down1 * down2;
                up2 = gcd(up1, down1);
                up1 = up1 / up2;
                down1 = down1 / up2;
                result = up1.ToString() + "/" + down1.ToString();
                return result;
            }
            if (type == 2)
            {
                up1 = (up1 * down2 - up2 * down1);
                down1 = down1 * down2;
                up2 = gcd(up1, down1);
                up1 = up1 / up2;
                down1 = down1 / up2;
                result = up1.ToString() + "/" + down1.ToString();
                return result;
            }
            if (type == 3)
            {
                up1 = up1 * up2;
                down1 = down1 * down2;
                up2 = gcd(up1, down1);
                up1 = up1 / up2;
                down1 = down1 / up2;
                result = up1.ToString() + "/" + down1.ToString();
                return result;
            }
            if (type == 4)
            {
                up1 = up1 * down2;
                down1 = down1 * up2;
                up2 = gcd(up1, down1);
                up1 = up1 / up2;
                down1 = down1 / up2;
                result = up1.ToString() + "/" + down1.ToString();
                return result;
             
            }
           
            return result;
        }
        public string CalculateZfengsu(int up1,int down1)//判断及生成真分数
        {
            string result = "true";
            int mid = 0;
            
                if (up1 > down1)
                {
                    mid = down1;
                    down1 = up1;
                    up1 = mid;
                    result = up1.ToString() + "/" + down1.ToString();
                    return result;
                }
                    if (up1 == down1)
                    {
                        down1 += 3;
                        result = up1.ToString() + "/" + down1.ToString();
                        return result;
                    }

                    
                
                
          
            return result;
        }

　　一、公约数测试：

    gcd(int a, int b)

      二、整数加减乘除测试：

Calculate(int type, int op1, int op2)其中type为运算类型，op1，op2为整数。

    

         三、分数四则运算：

 CalculateFengsu(int up1, int down1, int up2, int down2, int type)其中up1，up2为分子，down1，down2为分母，type为运算类型。

   

       四、判断真分数：

        

    CalculateZfengsu(int up1,int down1)，up1，down1分别为分子分母。

   

         五、代码覆盖率：

       

         六、小结：

        刚开始做单元测试时，不知道从哪里下手，甚至把程序代码直接复制进去做单元测试，后来搜索网上的教程，在小组成员的帮助下才完成了单元测试。
