Cobertura + jenkins 单元测试代码覆盖率统计

1、新建一个maven工程，在src/main/java 下建一个CoverageTest.java 类

package test_junit;

public class CoverageTest {

    public CoverageTest() {
        // TODO Auto-generated constructor stub
    }

    public static void main(String[] args) {
        // TODO Auto-generated method stub

    }
    
    public static int  testadd(int x, int y){
        int c = 0;
        if(x == 10){
            c = x + y;
        }else{
            c = (x + y)*2;
        }
        return c;
    }
}

2、在src/main/java 新建一个测试类JunitTest.java

package junit;

import org.junit.Assert;
import org.junit.Test;

import test_junit.CoverageTest;

/**
 * Created by 000284 on 2017/2/6.
 */
public class JunitTest {
    @Test
    public void testadd(){
        int b = CoverageTest.testadd(5, 20);
        Assert.assertEquals(b,50);
    }


}

3、pom.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
