软件测试 第一次上机 胡潇

Posted 2020-06-25

一.junit、hamcrest和eclemma的安装：

1.junit和hamcrest在新建了junitHw1工程后在build path里通过add external jars添加junit－4.12.jar和hamcrest－all－1.3.jar。

2.eclemma在eclipse下点击help－eclipse marketplace－find－eclemma安装。

二.编写Triangle以及Triangletest:

1.判断三角形：

package junit;

public class triangle 
{
private static int equilateral = 1;
private static int isosceles = 2;
private static int scalene = 3;
private static int error = 4;

public int getEquilateral()
{
    return equilateral;
    
}


public int getIsosceles()
{
    return isosceles;
    
}

public int getScalene()
{
    return scalene;
    
}

public int getError()
{
    return error;
    
}

public int type(int a, int b, int c)
{
    if(a<=0||b<=0||c<=0)
    {
        return error;
    }
    else if(a+b<c||a+c<b||b+c<a)
    {
        return error;
    }
    else if(a!=b&&b!=c&&a!=c)
    {
        return scalene;
    }
    else if(a==b&&b==c)
    {
        return equilateral;
    }
    else if(a==b||a==c||b==c)
    {
        return isosceles;
    }
    return 0;
}

}

2.测试:

package junit;
import org.junit.Test;
import static org.junit.Assert.*;

public class triangletest {
    private triangle triangle = new triangle();
    @Test
    public void testNottriangel(){
        assertEquals(triangle.getError(),triangle.type(0, 2, 3));
    }
    @Test
    public void testScalene(){
        assertEquals(triangle.getScalene(),triangle.type(3, 2, 4));
    }
    @Test
    public void testIsosceles(){
        assertEquals(triangle.getIsosceles(),triangle.type(3, 2, 3));
    }
    @Test
    public void testEquilateral(){
        assertEquals(triangle.getEquilateral(),triangle.type(3, 3, 3));
    }
}

三.测试结果截图：

四个测试案例都通过，覆盖率94.9%
