尝试通过Selenium Grid独立jar 3.14在LINUX上创建FIREFOX驱动程序时如何解决SessionNotCreatedException异常 [英] How to solve SessionNotCreatedException exception when trying to create FIREFOX driver on LINUX through Selenium Grid standalone jar 3.14

问题描述

尝试通过Selenium独立jar 3.14创建驱动程序时，我遇到org.openqa.selenium.SessionNotCreatedException异常.

I am getting org.openqa.selenium.SessionNotCreatedException exception when trying to create driver through Selenium standalone jar 3.14.

我已经使用以下命令启动集线器和节点

I have used below commands to start hub and node

1)java -jar selenium-server-standalone-3.141.59.jar -role hub

1) java -jar selenium-server-standalone-3.141.59.jar -role hub

2)java -jar selenium-server-standalone-3.141.59.jar -role webdriver -hub

2) java -jar selenium-server-standalone-3.141.59.jar -role webdriver -hub http://192.xxx.xx.xxx:4444/grid/register -port 5556 -browser browserName=chrome,maxInstance=3 -browser browserName=firefox,maxInstance=3

尝试通过以下代码创建驱动程序

Trying to create driver through below code

System.setProperty("webdriver.gecko.driver",
System.getProperty("user.dir") + "/drivers/" +"geckodriver");
DesiredCapabilities caps = DesiredCapabilities.firefox();
caps.setBrowserName("firefox");
caps.setPlatform(Platform.LINUX);
caps.setVersion("64.0");
driver = new RemoteWebDriver(new URL("http://192.xxx.xx.xxx:4444/wd/hub"),caps);

我正在接受以下例外:

org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{browserName=firefox, moz:firefoxOptions={binary=Optional.empty, args=[], legacy=null, logLevel=null, prefs={}, profile=null}, platform=LINUX}], required capabilities = Capabilities [{}]

推荐答案

由于您的 Selenium Grid节点正在使用 geckodriver 与 Selenium Grid Hub ，因此您需要使用 geckodriver 的绝对位置来启动 Selenium Grid Node ，如下所示:

As your Selenium Grid Node is using geckodriver to communicate with the Selenium Grid Hub, so you need to initiate the Selenium Grid Node with the absolute location of the geckodriver as follows:

java -Dwebdriver.gecko.driver=/path/to/geckodriver -jar selenium-server-standalone-3.141.59.jar -role webdriver -hub http://192.xxx.xx.xxx:4444/grid/register -port 5556 -browser browserName=chrome,maxInstance=3 -browser browserName=firefox,maxInstance=3
