无法实现selenium网格

Question

下面是我的代码，我正在使用它来传递浏览器、节点和枢纽港来启动浏览器并执行测试，但是我得到了异常，尽管我能够设置selenium服务器。我把错误贴在代码下面。我使用mac book、Selenium3.4、Firefox55和Gecko0.18.0

public synchronized WebDriver setUp(String browser, String 
nodePort, String hubPort) throws MalformedURLException{

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setPlatform(Platform.MAC);
capabilities.setCapability(CapabilityType.BROWSER_NAME, browser);
capabilities.setCapability(ForSeleniumServer.PROXYING_EVERYTHING, 
true);
capabilities.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
capabilities.setCapability(CapabilityType.SUPPORTS_ALERTS, true);
capabilities.setCapability(CapabilityType.SUPPORTS_JAVASCRIPT, 
true);

if(browser.equals("firefox"))
    System.setProperty("webdriver.gecko.driver", 
System.getProperty("user.dir")+"//geckoDriver//geckodriver");
else if(browser.equals("chrome"))
    System.setProperty("webdriver.chrome.driver", 
System.getProperty("user.dir")+"//chromeDriver//chromeDriver");
driver = new RemoteWebDriver(new 
URL("http://localhost:"+nodePort+"/wd/hub"), capabilities);
driver.get("https://www.bookbaby.com");
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
System.out.println(driver.toString());
return driver;

下面是命令提示符中的日志

Answer 1

请在计算机中设置环境变量webdriver.gecko.driver及其值。

也可以在启动集线器或注册节点时传递参数webdriver.gecko.driver。就像

java -Dwebdriver.gecko.driver="path to the gecko driver" {jar} -role node/hub
