java - 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

问题描述

尝试通过 Selenium 独立 jar 3.14 创建驱动程序时出现 org.openqa.selenium.SessionNotCreatedException 异常。

我使用以下命令启动集线器和节点

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 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

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);

我得到以下异常：

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 [{}]

解决方案

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

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
