java - 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，但在设置它时遇到问题。我无法启动 Firefox。我的代码如下，之后是错误堆栈。

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:这是当我尝试在 ECLIPSE 中运行代码时控制台窗口中显示的内容。

...意味着您的程序无法启动/生成新的 GeckoDriver 服务。

使用Selenium v​​3.x、GeckoDriver和Firefox启动新的GeckoDriver服务并< em>Firefox 浏览器 session ，您需要传递Keywebdriver.gecko.driver以及设置为Value>GeckoDriver 通过 System.setProperty() 行的绝对路径，如下所示:

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，这是相当旧的。
• 您的 Selenium 客户端版本是 v3.141.59。
• 我们未知您的GeckoDriver版本。
• 我们未知您的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 .
• 将 GeckoDriver 升级至 GeckoDriver v0.24.0级别。
• GeckoDriver 存在于指定位置。
• GeckoDriver 对非 root 用户具有可执行权限。
• 将 Firefox 版本升级至 Firefox v65.0 级别。
• 通过IDE清理您的项目工作区，并仅使用所需的依赖项重建项目。
• 如果您的基本网络客户端版本太旧，请通过 Revo Uninstaller 卸载它并安装最新的 GA 和已发布版本的Web 客户端。
• 重新启动系统。
• 以非 root 用户身份执行测试。
• 始终在 tearDown(){} 方法中调用 driver.quit() 来关闭和销毁 WebDriver 和 Web Client 优雅地实例化。
