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


public static void main (String args[]){

    System.setProperty("webdriver.gecko.driver", 
    "/usr/local/bin/geckodriver");      
    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.google.com");
    driver.quit();
  }

任何想法将不胜感激。谢谢。

尝试 Debanjan 建议后更新:

代码:

public static void main (String args[]){
    System.out.println("Debug 1");
    System.setProperty("webdriver.gecko.driver", 
    "/Users/maggie/Documents/ToolsQA/Libs/geckodriver");    
    System.out.println("Debug 2");
    WebDriver driver = new FirefoxDriver();
    System.out.println("Debug 3");
    driver.get("http://www.google.com");
    driver.quit();
  }

包含库:

selenium-server-standalone-3.7.1.jar

Answer 1

错误 WebDriverException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:8970 可能由于不同的原因而发生。此外，您的包含的库列表中存在差异，因为selenium-server-standalone-3.7.1.jar从来不是下载的selenium-java-3.7.1.zip的一部分。

尝试下面提到的步骤:

• 从包含的库列表中删除所有jar。
• 从 this link 仅下载和添加selenium-server-standalone-3.7.1.jar或来自this link

• 确保您系统上的 /etc/hosts 包含以下条目:

  1 127.0.0.1               localhost.localdomain localhost
  

• 运行CCleaner工具来清除系统中的所有OS杂务。

• 您可以选择系统重新启动。
• 执行您的测试。
