不是abe在VM上执行我的selenium测试

Question

我想使用Selenium网格运行我的Selenium测试。为此，我在本地机器（Ubuntu）上设置了集线器，并在Centos VM上设置了节点。我已经运行了以下命令：

null

          DesiredCapabilities cap1=new DesiredCapabilities();
          String hubURL = "http://10.242.2.6:4444/wd/hub";
          cap1.setBrowserName(browser);
          ChromeOptions option=new ChromeOptions();
          option.addArguments("--headless","--no-sandbox");
          option.merge(cap1);
          driver=new RemoteWebDriver(new URL(hubURL),option);
          driver.get("http://practice.automationtesting.in/my-account/");
          driver.findElement(By.id("username")).sendKeys("pavanoltraining");
          driver.findElement(By.id("password")).sendKeys("Test@selenium123");
          driver.findElement(By.name("login")).click();

我试过所有可能的解决办法，但还是想不出这个问题。

试试这个：

            private WebDriver driver;
            private ChromeOptions chromeOptions;
            private DesiredCapabilities caps;
            // Test on VM
            private final String URL = "http://10.242.2.6:4444/wd/hub";
            ChromeOptions options = new ChromeOptions();
            options.addArguments("--headless");
            options.setCapability(CapabilityType.BROWSER_NAME, "chrome");
            options.setCapability(CapabilityType.PLATFORM_NAME, Platform.LINUX);
            options.addArguments("Proxy", "null");
            options.setExperimentalOption("useAutomationExtension", false);
            options.addArguments("--disable-dev-shm-usage");
            options.addArguments("--no-sandbox");
            options.addArguments("window-size=1920,1080");
            options.addArguments("--disable-gpu");
            options.addArguments("start-maximized");
            options.addArguments("--allow-insecure-localhost");
            options.addArguments("--ignore-certificate-errors");
            System.out.println(options);
            driver = new RemoteWebDriver(new URL(URL), options);
            driver.manage().window().fullscreen();

我测试过了，这对我有效。如果您实际上已经将节点连接到集线器，并且在控制台中看到了这一点，那么这应该可以工作。
