软件测试:lab1.Junit and Eclemma

Task:

  1. Install Junit(4.12), Hamcrest(1.3) with Eclipse
  2. Install Eclemma with Eclipse
  3. Write a java program for the triangle problem and test the program with Junit.

  a)  Description of triangle problem:

  Function triangle takes three integers a,b,c which are length of triangle sides; calculates whether the triangle is equilateral, isosceles, or scalene.

 

Report:

  Junit:http://mvnrepository.com/artifact/junit/junit/4.12

  Hamcrest:http://mvnrepository.com/artifact/org.hamcrest/hamcrest-all/1.3

  Eclemma:https://sourceforge.net/projects/eclemma/

 

  1. Junit(4.12), Hamcrest(1.3)安装与配置

   eclipse中新建Java项目scs2015,再在该项目下新建目录lib,将hamcrest-all-1.3.jar,junit-4.12.jar拷贝到lib目录下,并导入项目里;

  2. Eclemma的安装与配置

   eclipse中—点击Help菜单—Install New Software,在弹出的对话框中,点击Add,之后点击 Archive,找到你下载好的 Eclemma.zip 资源文件,按照提示一步一步的安装重新启动 eclipse就完成了;

 

  3. Test triangle program with Junit

   点击安装Eclemma后工具栏上新增的覆盖测试按钮,来使用Eclemma测试Java程序

   

   测试结果如上图所示。

   在 Java 编辑器中,EclEmma 用不同的色彩标示了源代码的测试情况。其中,绿色的行表示该行代码被完整的执行,红色部分表示该行代码根本没有被执行,而黄色的行表明该行代码部分被执行。黄色的行通常出现在单行代码包含分支的情况,例如上图中的 20 行就显示为黄色。

   除了在源代码编辑窗口直接进行着色之外,EclEmma 还提供了一个单独的视图来统计程序的覆盖测试率。

   由于Triangle.java中还有一些get set 方法行没有被测试覆盖,上图Coverage为52.6%,尝试删去多余代码行后视图显示如下:

 

 

   代码附录:

   Triangle.java

public class Triangle {
    private double side1,side2,side3;

    public Triangle(double side1, double side2, double side3) {
        super();
        this.side1 = side1;
        this.side2 = side2;
        this.side3 = side3;
    }

    public String getShape() {
        String sha[]= {"equilateral","isosceles", "scalene"};
        int i=-1;
        if(this.side1!=this.side2&&this.side1!=this.side3&&this.side2!=this.side3) {
            i=2;
        }else if(this.side1==this.side2&&this.side2==this.side3) {
            i=0;
        }else {
            i=1;
        }        
        return sha[i];
    }
}

   TriangleTest.java

public class TriangleTest {

    @Test
    public void testEquilateral() {
        double a1=1,a2=1,a3=1;
        Triangle tria=new Triangle(a1, a2, a3);
        assertEquals("equilateral",tria.getShape());
    }
    
    @Test
    public void testIsosceles() {
        double b1=1,b2=1,b3=1.2;
        Triangle trib=new Triangle(b1, b2, b3);
        assertEquals("isosceles",trib.getShape());
    }
    
    @Test
    public void testScalene() {
        double c1=3,c2=4,c3=5;
        Triangle tric=new Triangle(c1, c2, c3);
        assertEquals("scalene",tric.getShape());
    }
    
}
