软件开发工具与环境实验报告实验（训）报告实验名称实验七 白盒测试 实验目的掌握白盒测试的几种逻辑覆盖方法一、实验题目1、任意输入三个整数a,b,c，比较三个数的关系。要求：输入：三个参数（比较的三个整数）输出：三个数的大小关系1）使用所学语言编写程序实现可视化界面。（vc+/java/c#）2）画出上面函数的流程图。3）分别使用语句覆盖、判定覆盖（也称为分支覆盖）、条件覆盖、判定-条件覆盖、条件组合测试、 路径测试设计测试用例（注意测试用例的格式）。 4）执行每个测试用例，执行完毕后填写测试用例二、实验内容及结果(请将相应题目代码和结果截图写在相应题目下方)1.代码： using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace Three_integer_relation public partial class frm_relation : Form public frm_relation() InitializeComponent(); private void button1_Click(object sender, EventArgs e) int a = Convert.ToInt32(txt_a.Text); int b = Convert.ToInt32(txt_b.Text); int c = Convert.ToInt32(txt_c.Text); int temp; if (a b) if (b c) lab_show.Visible = true; lab_show.Text = a.ToString() + + b.ToString() + + c.ToString(); else if (b c & c + b.ToString() + + c.ToString(); else if (b a) temp = b; b = c; c = temp; temp = b; b = a; a = temp; lab_show.Visible = true; lab_show.Text = a.ToString() + + b.ToString() + + c.ToString(); else if(b + c.ToString(); else if (b = c) lab_show.Visible = true; lab_show.Text = a.ToString() + + b.ToString() + = + c.ToString(); else if (a c) lab_show.Visible = true; lab_show.Text = a.ToString() + + b.ToString() + + c.ToString(); else if (b c) temp = b; b = c; c = temp; lab_show.Visible = true; lab_show.Text = a.ToString() + + b.ToString() + + c.ToString(); else if (b c & a + b.ToString() + + c.ToString(); else if (b + c.ToString(); else if (b = c) lab_show.Visible = true; lab_show.Text = a.ToString() + + b.ToString() + = + c.ToString(); else if (b c) lab_show.Visible = true; lab_show.Text = a.ToString() + = + b.ToString() + + c.ToString(); else if (b + b.ToString() + = + c.ToString(); else lab_show.Visible = true; lab_show.Text = a.ToString() + = + b.ToString() + = + c.ToString(); private void btn_exist_Click(object sender, EventArgs e) this.Close(); 结果： 2.函数的流程图： 3.测试用例： (1).语句覆盖： 测试用例输入输出判定(ab)的取值判定(a2510TFF(1)(2)(5)(8)a=98;b=25;c=50985025TFF(1)(2)(5)(9)(11)a=98;b=98;c=9898=98=98FFT(1)(3)(6)a=98;b=125;c=251259825FTF(1)(4)(7)(17)a=98;b=125;c=12012512098FTF(1)(4)(7)(19)(17) (2).判定覆盖 测试用例输入输出判定(ab)的取值判定(a2510TFF(1)(2)(5)(8)a=98;b=25;c=50985025TFF(1)(2)(5)(9)(11)a=98;b=98;c=9898=98=98FFT(1)(3)(6)a=98;b=125;c=251259825FTF(1)(4)(7)(17) (3).条件覆盖测试用例输入输出取值条件覆盖路径a=98;b=25;c=10982510abc(1)(2)(5)(8)a=98;b=25;c=50985025ab,bc(1)(2)(5)(9)(11)a=98,b=50,c=1251259850ab,ba(1)(2)(5)(9)(13)a=98,b=98,c=9898=98=98a=b=c(1)(3)(6)a=98,b=125,cb,b10098ac,a9825ac,ac(1)(4)(7)(14) (4).判定-条件覆盖测试用例输入输出取值条件覆盖路径a=98;b=25;c=10982510abc(1)(2)(5)(8)a=98,b=50,c=1251259850ab,ba(1)(2)(5)(9)(13)a=98,b=125,c=251259825ac,ac(1)(4)(7)(14) (5).条件组合测试测试用例输入输出覆盖条件取值覆盖路径a=98;b=25;c=10982510abc(1)(2)(5)(8)a=98;b=25;c=50985025ab,bc(1)(2)(5)(9)(11)a=98,b=98,c=9898=98=98a=b=c(1)(3)(6)a=98,b=125,c=251259825ac,ac(1)(4)(7)(14)a=98,b=125,c=10012510098ac,a2510abc(1)(2)(5)(8)a=98,b=25,c=1231239825ab,bc (1)(2)(5)(9)(11)a=98,b=25,c=9898+9825ab,b9825ab,ba,a25=25ab,b=c(1)(2)(5)(10)a=25,b=25,c=2525=25=
