软件测试3

小试：利用junit、eclemma测试代码

1.安装junit

将下载的jar加载进新建的项目即可

右键项目->properties->java build path->libraries->add external jars 选择jar的位置即可

2.安装eclemma

下载eclemma->help->install new software->add->选择下载好的eclemma压缩包的位置->next  等待安装（需要重启eclipse）

3.代码

三角形检测函数代码

package softwareTest;

public class TriangleDetect {
    
    
    
    public   TriangleDetect()
    {
        
    }
    public boolean isTri(int a1,int a2,int a3)
    {
        if(((a1+a2)>a3)&&((a1+a3)>a2)&&((a2+a3)>a1))
        {
            return true;
        }
        else
        {
            return false;
        }
    }
    public String  test(int b1,int b2,int b3)
    {
        
        
        
        if(isTri(b1,b2,b3))
        {
            if((b1==b2)&&(b2==b3))
            {
                return "equilateral";
            }
            else if((b1==b2)||(b2==b3)||(b1==b3))
            {
                return "isosceles";
            }
            else 
            {
                return "scalene";
            }
        }
        else 
        {
            return "not a triangle";
        }
        
    }

}

测试代码

package softwareTest;
import java.util.Arrays;
import java.util.Collection;

import org.junit.*;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;
import org.junit.runner.RunWith;

import static org.junit.Assert.*;


    
    @RunWith(Parameterized.class)
    public class TestPara
    {
        private int input1;
        private int input2;
        private int input3;
        private String expected;
        private TriangleDetect t;
        public TestPara(int input1,int input2,int input3,String expected){
            this.input1 = input1;
            this.input2 = input2;
            this.input3 = input3;
            this.expected = expected;
            } 
        @Before
        public void setUp(){
            t = new TriangleDetect();
            }
        @Parameters
        public  static Collection<Object[]> getData(){
        return Arrays.asList(new Object[][]{
        {1,1,1,"equilateral"},
        {2,3,3,"isosceles"},
        {3,5,7,"scalene"}
        });
        }
        @Test
        public void testTri() {
            assertEquals(this.expected,t.test(input1, input2, input3));
            }
        
    }
