selenium-webdriver - 将 webdriver 采样器脚本运行到远程机器时出现 Jmeter 错误

问题描述

我的 webdriver 采样器代码如下：

var pkg = JavaImporter(org.openqa.selenium); //WebDriver classes
var support_ui = JavaImporter(org.openqa.selenium.support.ui.WebDriverWait); //WebDriver classes
WDS.sampleResult.sampleStart()
var wait = new support_ui.WebDriverWait(WDS.browser, 5000);
WDS.browser.manage().timeouts().implicitlyWait(25, TimeUnit.SECONDS); 
WDS.browser.get('http://interview.erainfotechbd.com:5003/')
WDS.log.info("chat bot opended")
//var name= WDS.args[0]
//var number= WDS.args[1]
WDS.log.info("names are :" +WDS.args[0])
WDS.log.info("numbers are :" +WDS.args[1])
var wait=new support_ui.WebDriverWait(WDS.browser, 5)
WDS.browser.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS); 
var userName = WDS.browser.findElement(pkg.By.xpath('//input[@name="nickname"]'))
userName.click(); //clicks search field
userName.sendKeys(WDS.args[0]) //types word "blazemeter" in field//saves search field into searchField
var mobileNumber = WDS.browser.findElement(pkg.By.xpath('//input[@name="mobile"]'))
mobileNumber.click(); //clicks search field
mobileNumber.sendKeys(WDS.args[1]) //types word "blazemeter" in field//saves search field into searchField
var loginButton = WDS.browser.findElement(pkg.By.xpath('//button[@id="Enter"]'))
loginButton.click(); //clicks login button
var wait=new support_ui.WebDriverWait(WDS.browser, 5)
var selectInterview= WDS.browser.findElement(pkg.By.xpath('//form[@id="myFormInt"]/input[1]'))
selectInterview.click()
var wait=new support_ui.WebDriverWait(WDS.browser, 20)
//timeouts.pageLoadTimeout(600, timeUnit.TimeUnit.SECONDS)
var returnedAnswer=WDS.browser.findElement(pkg.By.xpath('//input[@class="form-control"]')).getText()
var enterValidNumber= WDS.browser.findElement(pkg.By.xpath('//input[@class="form-control"]'))
enterValidNumber.sendKeys('01676912613')
var sendMessagebutton= WDS.browser.findElement(pkg.By.xpath('//button[@id="sendMessage"]'))
sendMessagebutton.click()
var wait=new support_ui.WebDriverWait(WDS.browser, 20)
//timeouts.pageLoadTimeout(600, timeUnit.TimeUnit.SECONDS)
WDS.vars.put('renderTime', renderTime.toString())
WDS.sampleResult.getLatency()
WDS.sampleResult.sampleEnd()

我已将我的主 jmeter 服务器配置如下：

server.rmi.ssl.disable=true
remote_hosts=127.0.0.1 , 10.11.200.203

运行我的脚本后，它给从机（10.11.200.203）以下异常

虽然它给出了这个例外，但经过一段时间 chromedriver open chorme 但它没有执行进一步的脚本，如浏览 url、登录等。

可能的原因是什么？

解决方案

我发现了问题。问题是我的机器上有docker。当我在 master 上运行我的 jmeter 服务器时，我看到该服务器以 Docker vEthernet IP 开头。所以我禁用了 vEthernet（Docker NAT）。现在它正在工作。
