Java项目中的linux Selenium Chromedriver超时问题

3 月，2 周 Questions & Answers 547

我不知道如何正确配置selenium测试以在Ubuntu VM中运行。不过，在我有EclipseIDE的Windows上，它可以正常工作。以下是testNGclass的java代码的一部分：

@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 + "/");

我一直从testNG报告中得到的错误是这样的（除了localhost:端口，每次运行它时都会发生变化）

我已经检查了linux上的chromedriver文件路径，没有问题，该文件具有可执行权限。我是否也必须在linux机器上启动chromedriver可执行文件？除了运行编译后的java项目，我还需要做其他事情吗

有 Java 编程相关的问题?
