软件测试第一次实验

Posted 2020-10-28 yuchunyu97

实验环境：Mac + IDEA + junit-4.12 + hamcrest-core-1.3

首先安装 Junit（测试） 和 Hamcrest（测试覆盖）

下载地址：https://github.com/junit-team/junit4/wiki/Download-and-Install

需要下载两个 jar 包：junit-4.12.jar 和 hamcrest-core-1.3.jar

首先建立项目 Lab1



填写项目名称和项目路径

然后创建一个 JavaClass ：Triangle


编写代码：

/**

 */
public class Triangle {
    private int one;
    private int two;
    private int three;

    public static boolean isLegal(int len1, int len2, int len3) {
        if (len1 <= 0 || len2 <= 0 || len3 <= 0)
            return false;

        if (len1 + len2 > len3 && len2 + len3 > len1 && len1 + len3 > len2)
            return true;

        return false;
    }

    public Triangle(int side_1, int side_2, int side_3) {
        if (isLegal(side_1, side_2, side_3)) {
            one = side_1;
            two = side_2;
            three = side_3;
        } else
            one = two = three = 1;
    }

    public boolean isEquilatera() {
        // 等边三角形
        return (one == two && one == three);
    }

    public boolean isIsosceles() {
        // 等腰三角形
        return (one == two || one == three || two == three);
    }

    public boolean isScalene() {
        // 不等边三角形;
        return !isEquilatera();
    }
}

然后创建测试用例
使用快捷键：Command + Shift + T

填写相应的设置信息

在写测试代码之前，需要先引用之前下好的两个 jar 包
新建一个目录 lib

将两个 jar 包拷贝dao到 lib 目录下

然后点击 File - Project Structure - Libraries - +


从 lib 目录下将两个 jar 包引入

点 OK 保存
然后编写测试代码

import org.junit.Before;
import org.junit.Test;

import static org.junit.Assert.*;

/**
 * Created by yuchunyu97 on 2018/3/22.
 */
public class TriangleTest {
    private Triangle tri1;
    private Triangle tri2;
    private Triangle tri3;
    private Triangle tri4;

    @Before
    public void setUp() throws Exception {
        tri1 = new Triangle(3, 3, 3);
        tri2 = new Triangle(3, 3, 5);
        tri3 = new Triangle(3, 4, 5);
        tri4 = new Triangle(-3, 4, 5);
    }

    @Test
    public void isEquilatera() throws Exception {
        // 等边三角形
        assertTrue(tri1.isEquilatera());
    }

    @Test
    public void isIsosceles() throws Exception {
        // 等腰三角形
        assertTrue(tri2.isIsosceles());
    }

    @Test
    public void isScalene() throws Exception {
        // 不等边三角形
        assertTrue(tri3.isScalene());
        assertTrue(tri4.isScalene());
    }

}

然后进行测试
点击运行按钮下的：Run ‘TriangleTest‘ with Coverage

就可以看到测试的结果了
