org.openqa.selenium.WebDriverException: java.net.ConnectException: 无法使用 GeckoDriver 和 Selenium 连接到 localhost/0:0:0:0:0:0:0:1:1941

Question

我正在尝试使用 Eclipse 编写一个简单的自动化测试，但在设置时遇到了问题。 我一直无法启动 Firefox。 我的代码在下面，然后是错误堆栈。

代码：

package cucumberTest;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class seleniumTest {

    private static WebDriver driver = null;

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        //https://www.toolsqa.com/cucumber/first-cucumber-selenium-java-test/
        // new instance of frefox driver
        driver = new FirefoxDriver();

         //Put a Implicit wait, this means that any search for elements on the page 
         // could take the time the implicit wait is set for before throwing exception

        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

        //open page
         driver.get("http://www.store.demoqa.com");

错误堆栈：这是我尝试在 ECLIPSE 中运行代码时控制台窗口中显示的内容。

这个错误信息...

...暗示您的程序无法启动/生成新的GeckoDriver服务。

虽然与硒3.x版工作，GeckoDriver和Firefox启动新GeckoDriver服务和Firefox浏览器会话，你需要通过传递与值设置为GeckoDriver的绝对路径沿着键webdriver.gecko.driver System.setProperty()行如下：

System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
driver = new FirefoxDriver();

此外，

• 您的JDK 版本是1.8.0_161 ，这已经很旧了。
• 您的Selenium 客户端版本是v3.141.59 。
• 我们不知道您的GeckoDriver版本。
• 我们不知道您的Firefox版本。

因此JDK v8u161和Selenium Client v3.141.59之间存在明显的不匹配。

解决方案

• 将JDK升级到最新级别JDK 8u202 。
• 升级GeckoDriver到GeckoDriver v0.24.0水平。
• GeckoDriver 存在于指定位置。
• GeckoDriver 对非 root 用户具有可执行权限。
• 将Firefox版本升级到Firefox v65.0级别。
• 通过IDE清理项目工作区并仅使用所需的依赖项重建项目。
• 如果您的基本Web Client版本太旧，请通过Revo Uninstaller卸载它并安装最新的 GA 和发布版本的Web Client 。
• 进行系统重启。
• 以非 root 用户身份执行您的Test 。
• 始终在tearDown(){}方法中调用driver.quit()以优雅地关闭和销毁WebDriver和Web Client实例。
