如果在Jenkins上终止测试，则Selenium驱动程序实例仍然存在 [英] Selenium driver instance persists if test is aborted on Jenkins

问题描述

好的，所以我想知道如果通过jenkins中止测试，如何使我的驱动程序/浏览器会话正确退出.在本地，如果我运行测试并中止测试，浏览器将正确退出.但是，通过詹金斯(Jenkins)不会发生这种情况.如果我在硒网格上运行测试的测试阶段中止该作业，则浏览器保持打开状态-导致该节点仍显示为正在使用，因为它没有意识到该中止的作业本应杀死其浏览器会话

Ok, so I am wondering how I can get my driver/browser sessions to properly exit if a test is aborted via jenkins. Locally, if I run my tests and abort them, the browser will quit properly. Via jenkins however, this does not happen. If I abort the job during the test phase where my tests are running on the selenium grid, the browser stays open - causing the node to still show up as being used because it did not pick up that the aborted job should have killed its browser session.

我一直在搞黄瓜钩子，但是我想得更多，所以我不确定是否可以用钩子来解决这个问题，因为在本地运行时不会发生这种情况.我现在认为这应该是硒网格或詹金斯的设置.

I have been messing around with cucumber hooks, but the more I think about it I am not sure if I can handle this with a hook since when ran locally this behavior does not happen. I am now thinking this needs to be either a setting on the selenium grid or jenkins.

我最理想的解决方案是使用一个类似于下面的钩子，该钩子可以判断它是否正在远程运行，并在中止/通过/失败时终止会话.但是，如果通过詹金斯或硒网格设置有任何解决方案，那也将非常棒！谢谢！

My most optimal solution would be to use a hook like the one below that could tell if it was being run remotely and kill the session if aborted/passed/failed. But if there is any solution via jenkins or the selenium grid settings that would be great too! Thank you!

this.registerHandler('After', function (event, done) {
     // Some code to clear browser session 
    done();
});

推荐答案

我认为您无需在客户端代码上做任何额外的事情.

I dont think you need to do anything extra here at your client code.

Selenium Grid专门具有用于进行此类清理的三个参数.

The selenium Grid specifically has three parameters that are meant for these sort of cleanups.

• -browserTimeout (以秒为单位):运行WebDriver命令时允许浏览器会话挂起的秒数(示例:driver.get(url)).如果仍在处理WebDriver命令时达到超时，则会话将退出.最小值为60.未指定，零或负值表示无限期等待. Default: 0

• -browserTimeout in seconds : number of seconds a browser session is allowed to hang while a WebDriver command is running (example: driver.get(url)). If the timeout is reached while a WebDriver command is still processing, the session will quit. Minimum value is 60. An unspecified, zero, or negative value means wait indefinitely. Default: 0

-cleanUpCycle (以毫秒为单位):指定集线器多久轮询一次正在运行的代理，以了解是否存在超时(即挂起)线程.还必须指定 timeout 选项. Default: 5000 (5秒)

-cleanUpCycle in milliseconds : specifies how often the hub will poll running proxies for timed-out (i.e. hung) threads. Must also specify timeout option.Default: 5000 (5 seconds)

-timeout ， -sessionTimeout (以秒为单位):指定在服务器自动终止最近一次没有任何活动的会话之前的超时X秒.然后将释放测试插槽，以供其他测试使用.这通常用于照顾客户端崩溃.对于网格中心/节点角色，还必须设置cleanUpCycle. Default: 1800

-timeout, -sessionTimeout in seconds : Specifies the timeout before the server automatically kills a session that hasn't had any activity in the last X seconds. The test slot will then be released for another test to use. This is typically used to take care of client crashes. For grid hub/node roles, cleanUpCycle must also be set. Default: 1800

结合使用以上三个参数，可以将节点配置为自动关闭孤立的浏览器实例和会话.

Using a combination of all the above 3 parameters, you can configure your node to automatically close orphaned browser instances and sessions.
