Question

我正在尝试安装/配置Selenium，以便在团队成员不在办公室时进行一些UI测试。我安装了Selenium Webdriver和Eclipse，以及Chrome，Firefox和Edge浏览器驱动程序。我有一些非常简单的脚本启动浏览器并打开一个URL。我只是想验证我的安装和配置是否正常。 Firefox和Edge很好，按预期工作。但是，我无法让chrome工作。

这是我的剧本：

package firstPackage;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;

public class FirstScript {
    public static void main(String[] args) {        
        ChromeOptions options = new ChromeOptions();
        options.addArguments("disable-infobars");
        options.addArguments("--start-maximized");

        WebDriver driver = new ChromeDriver(options);
        driver.get("http://www.google.com");
    }
}

当我运行它时，Chrome会启动。标签的标题是“数据”;并且地址栏中的URL也是“data;”。但是，浏览器不会导航到我指定的URL。大约60秒后，我在eclipse窗口中收到以下错误：

谷歌搜索带我到一些帖子，建议一些选项设置可能会解决问题。这些是我试过的：

options.addArguments("--disable-extensions"); // disabling extensions
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--disable-dev-shm-usage"); // overcome limited resource problems
options.addArguments("--no-sandbox"); // Bypass OS security model

这些都没有解决我的问题，行为保持不变。

我正在跑步： Windows 10（操作系统版本16299）硒3.12.0 ChromeDriver 2.39 Chrome 67.0.3396.79

任何人都有任何关于我可能做错的建议吗？

我通过添加--headless选项在Ruby中解决了这个问题。也许有帮助。
