jenkins部署成功执行自动化测试代码失败问题解决

一.问题描述

我的jenkins运行在虚拟机上，mysql服务在主机上；
1.先执行jenkins的deploy任务，拉取远程开发代码并进行部署
2.deploy任务部署完成触发部署test任务，运行自动化代码进行测试

问题出在test任务构建显示success，但是测试代码并没有执行成功

二.问题解决-数据库权限

按照报错提示去target目录下看运行结果报告

org.apache.ibatis.exceptions.PersistenceException:
)### Error querying database.  Cause: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES
### The error may exist in mapper/SQLMapper.xml
### The error may involve com.course.model.loginCase
### The error occurred while executing a query
### Cause: java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)at org.apache.ibatis.exceptions.ExceptionFactory.wrapException(ExceptionFactory.java:30)at org.apache.ibatis.session.defaults.DefaultSqlSession.selectList(DefaultSqlSession.java:150)at org.apache.ibatis.session.defaults.DefaultSqlSession.selectList(DefaultSqlSession.java:141)at org.apache.ibatis.session.defaults.DefaultSqlSession.selectOne(DefaultSqlSession.java:77)at com.course.cases.LoginTest.loginTrue(LoginTest.java:51)

显示无法访问到mysql数据库，检查了一下我的用户名密码写的是对的，解决如下：
1.尝试在cmd命令行把root用户的访问权限由localhost->所有主机

mysql -u root -p
CREATE USER 'root'@'%' IDENTIFIED BY '密码';
grant all privileges on *.* to 'root'@'%'
flush privileges;
exit

再次登录即可。
2.并且在配置文件里把连接mysql的url由127.0.0.1改成本机IP，

3.提交代码到github

git add .
git status
git commit -m "修改数据库连接地址"
git push

4.再次在jenkins上执行deploy任务，这次test任务还是没有执行成功

5.查看surefire报告报错
6.到jenkins运行工作目录
/root/.jenkins/workspace/deploy/Chapter13/target/logs

[root@fanyu logs]# ll
总用量 16
-rw-r--r--. 1 root root     0 6月  13 12:17 event.log
-rw-r--r--. 1 root root 13666 6月  13 12:18 userManger.log

查看一下本次deploy服务端程序启动信息

server logs：
Caused by: org.apache.catalina.LifecycleException: Protocol handler start failedat org.apache.catalina.connector.Connector.startInternal(Connector.java:1021)at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150)... 21 common frames omitted

三.问题解决-端口占用

1.检查了一下，我的jenkins服务在用的是8080端口，

[root@fanyu logs]# ps -ef | grep 8080
root       3201   3022  0 08:18 pts/1    00:01:31 java -jar jenkins.war -httpPort=8080
root      10086   3022  0 12:34 pts/1    00:00:00 grep --color=auto 8080

服务端程序在用的也是8080端口；

2.于是便修改端口为8081（并把8081端口加入到防火墙的开放端口中）
示例：

[root@fanyu ~]# firewall-cmd --list-ports    列出开放端口
8080/tcp 3306/tcp 80/tcp 6379/tcp 8081/tcp
[root@fanyu ~]# firewall-cmd --zone=public --add-port=8082/tcp --permanent      增加开放端口
success
[root@fanyu ~]# firewall-cmd --reload     重启防火墙
success
[root@fanyu ~]# firewall-cmd --list-ports
8080/tcp 3306/tcp 80/tcp 6379/tcp 8081/tcp 8082/tcp

3.再次启动deploy任务，test任务

4.test任务依旧报错，查看报告：

loginFalse
org.apache.ibatis.exceptions.PersistenceException: ### Error querying database. Cause: com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. ### The error may exist in mapper/SQLMapper.xml ### The error may involve com.course.model.loginCase ### The error occurred while executing a query ### Cause: com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago.

Removed 37 stack frames

大意是连接超时，没有得到服务器的响应包；

四.问题解决-连接超时

1.尝试在本机ping虚拟机
发现可以ping通

2.尝试在虚拟机ping主机
发现连接超时

3.在网上查了下资料是本机的防火墙原因，Windows10的防火墙没有打开ICMPv4-in规则
于是解决如下：
1）打开设置，搜索防火墙

2）点击高级设置
3）点此更改防火墙属性

4）确保更改过后是这样的效果

5）点击入站规则，启动这个规则

再次虚拟机ping主机，发现可以ping通了

再次在jenkins启动任务，发现还是报错

loginFalse
java.lang.NullPointerException at com.course.cases.LoginTest.getResult(LoginTest.java:96) at com.course.cases.LoginTest.loginFalse(LoginTest.java:119) at com.sun.proxy.$Proxy0.invoke(Unknown Source) ... Removed 33 stack frames

检查这行代码，发现

是因为response为空，所以产生了空指针异常，也就是没有得到响应

五.问题解决-请求无响应

1.不通过jenkins在本机终端尝试运行测试代码
也是报错的，报错如下：

12:53:08.671 [main] DEBUG com.course.model.loginCase - ==>  Preparing: select * from login_case where id=?
12:53:08.671 [main] DEBUG com.course.model.loginCase - ==> Parameters: 1(Integer)

Caused by: java.net.ConnectException: Connection refused: connectat java.net.DualStackPlainSocketImpl.connect0(Native Method)at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:79)at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:345)at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206)at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188)at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172)at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392)at java.net.Socket.connect(Socket.java:589)

可以看出测试代码访问数据库都是正常的，但是请求服务端连接被拒绝了。

2.jenkins运行deploy任务和test任务
test任务 console output每一个测试方法也都是提示连接超时

3.确保服务端程序确实是起着的之后，检查了下请求的IP

这个是本机的IP，
因为
服务端程序和测试程序都是运行在虚拟机，这时候请求的地址应该是虚拟机的IP地址；

于是更改访问地址

不要忘了提交代码到git上

git代码更新后
再次执行jenkins的deploy和test任务，
服务器日志能正常响应：

test任务output：

查看extentreport报告
（cd /root/.jenkins/workspace/test/Chapter12/test-output）

[root@fanyu Chapter12]# cd test-output/
[root@fanyu test-output]# ll
总用量 20
-rw-r--r--. 1 root root 20477 6月  13 13:21 index.html

这表明test任务执行成功了
