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

     
         
      
       4.0.0
          
      
       testunit
          
      
       test_junit
          
      
       1.0-SNAPSHOT
       
              
               
                   
        
         jenkins
                    
                        
                             
          
           env.BUILD_NUMBER
                          
                     
                    
                        
                             
           
           
            org.codehaus.mojo
            
           
            cobertura-maven-plugin
            
           
            2.7
            
            
             
             
              xml
              
             
            
            
             
             
              package
              
              
              
               cobertura
               
              
             
            
                          
                     
                
           
          
              
                   
        
         junit
                    
        
         junit
                    
        
         4.12
                
           
      
     

3、jenkins 安装插件cobertura

4、新建jenkins job

build >Goals and options  设置：clean cobertura:cobertura

Cobertura xml report pattern 设置： **/target/site/cobertura/coverage.xml

post setps 设置：Enable the "Publish Cobertura Coverage Report" publisher

5、构建job 查看 Coverage Report 就会显示覆盖率报表
