Selenium Grid：DevToolsActivePort文件不存在（未知错误：Chrome无法启动：异常退出）

标签： java linux google-chrome selenium-webdriver selenium-chromedriver

我正在尝试使用Selenium Grid来自动化一些测试。为了优化测试时间，我创建了一些在LINUX平台上工作的VM（一个VM作为Selenium集线器，其他VM作为Selenium节点）。在集线器或节点中启动独立服务器时都没有问题（所有工作均符合预期：节点已成功连接到集线器）。但是，当尝试执行测试remoteWebDriver的Java代码（使用chrome）时，我得到了一个充满警告和错误的窗口！我认为chromedriver不高兴...有人知道如何解决这个问题吗？

以下是我正在使用的Java代码： 

import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

public class GithubTest {

  public static void main(String[] args) throws MalformedURLException{
    String toBeTestedUrl = "https://github.com";
    String nodeUrl = "http:172.20.10.13:5555/wd/hub";
    DesiredCapabilities desiredCapabilities = DesiredCapabilities.chrome();
    desiredCapabilities.setBrowserName(DesiredCapabilities.chrome().getBrowserName());
    desiredCapabilities.setPlatform(Platform.LINUX);
    WebDriver driver = new RemoteWebDriver(new URL(nodeUrl), desiredCapabilities);


    driver.get(toBeTestedUrl);

    if(driver.getTitle().equalsIgnoreCase("The world’s leading software development platform · GitHub"))
        System.out.println("OK!");
    else 
        System.out.println("ERROR!");

    driver.quit();
  }
}

以下是硒节点中的日志文件：

答案 0 :(得分：1)

首先要检查的是，您正在使用正确的Chrome驱动程序来驱动Chrome浏览器。如果不确定，请检查您的Chrome版本，然后从http://chromedriver.chromium.org/downloads重新下载驱动程序。据我所知，您的ChromeDriver是2.41，它仅支持Chrome v67-69，因此可能是兼容性原因。

如果没有帮助，则可能需要在驱动程序初始化中添加其他参数

chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
driver = webdriver.Chrome('/path/to/your_chrome_driver_dir/chromedriver',chrome_options=chrome_options)
