Question

下面是我用来传递浏览器，节点和集线器端口以启动浏览器并执行测试的代码，但我得到了例外，尽管我能够设置selenium服务器。我也在代码下面粘贴错误。我使用mac book，Selenium 3.4，Firefox 55和Gecko 0.18.0

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;

错误是

Answer 1

请在您的机器中设置环境变量webdriver.gecko.driver及其值。

或者您可以在启动集线器或注册节点时传递参数webdriver.gecko.driver。像

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

Answer 2

首先说明你的代码中的问题，如果你想使用selenium服务器/网格，请在启动selenium服务器时在命令行中指定webdriver路径，而不是通过代码指定。
所以下面的代码是不必要的，只有当你选择不使用selenium服务器/网格的运行测试时才需要它们，我们称它为“直接连接”。（您的脚本直接与webdriver.exe通信）

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug {
        testCoverageEnabled true
    }
}

将节点注册到hub参数示例以指定webdriver.exe路径：

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");

提醒：请检查standalone.jar，指定的webdriver.exe和节点上的浏览器是否相互兼容，否则节点将无法在测试中启动浏览器。

无法实施硒网格
