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 classTriangleTestMethod /*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 intcomfirm(inta,intb,intc) if(a + b > c) && (b + c > a) && (a + c > b) /判断为三角形if(a = b) && (b =c)/判断为等边三角

2、形return3;if(a = b) | (b = c) | (a = c)/判断为等腰三角形return2;else/判断为普通三角形return1;else/为非三角形return0;1.二、程序流程图NYRet ur n 3a + b > c && b + c> a && a + c > bYa = b && b =cNa = b |b =c |a = cNYRet ur n 1Ret ur n 2Ret ur n 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=2, c=3
