软件测试案例(三角形白盒测试)

1、一、核心程序代码/* 判断三角形的类 */public class TriangleTestMethod /* 判断三角形的种类。参数a, b, c分别为三角形的三边，* 返回的参数值为0，表示非三角形；* 为1，表示普通三角形；* 为2，表示等腰三角形；* 为3，表示等边三角形。*/public static int comfirm(int a, int b,int c) if(a + b > c) && (b + c > a) && (a + c > b) / 判断为三角形if(a = b) && (b =c) / 判断为等

2、边三角形return 3;if(a = b) | (b = c) | (a = c)/ 判断为等腰三角形return 2;else/ 判断为普通三角形return 1;else / 为非三角形return 0;1二、程序流程图Na + b > c && b + c> a && a + c > bY Ya = b && b =cNa = b | b = c |a = cNY Return 3Return 1Return 2Return 0Exit三、测试用例1.语句覆盖测试用例：输入期望输出覆盖对象测试结果Case1a=1, b=
