java - Java 项目中的 Selenium Chromedriver 超时问题

Question

我不知道如何正确配置 selenium 测试以在 Ubuntu VM 中运行。 在我有 eclipse IDE 的 Windows 上，虽然可以正常工作。 以下是 testNG 类的部分 java 代码:

@BeforeClass(alwaysRun = true)
public void setUp() throws Exception {   

    if (SystemUtils.IS_OS_LINUX)      
        System.setProperty("webdriver.chrome.driver", "/usr/bin/selenium/chromedriver/chromedriver");

    if(SystemUtils.IS_OS_WINDOWS)
        System.setProperty("webdriver.chrome.driver", ""+System.getProperty("user.dir").toString()+"/lib/chromedriver.exe");

    driver = new ChromeDriver();          

    System.out.println(System.getProperty("portletToTest"));  
    baseUrl = "http://www.google.it";
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}

@Test
public void test() throws Exception {
    driver.get(baseUrl + "/");

我不断得到的错误是这个，来自 testNG 报告(除了 localhost: 的端口，每次运行它时都会有所不同)

我已经仔细检查了linux上的chromedriver文件路径，没问题，文件有可执行权限。 我还必须在 linux 机器上启动 chromedriver 可执行文件吗？除了运行已编译的 java 项目，我还需要做其他事情吗？

您的 chrome 驱动程序应该具有与 chrome 浏览器相匹配的正确版本。
