Linux下Selenium+Geckodriver运行Java自动化测试报错求助

环境配置 #

• 操作系统：Fedora Linux 36（Workstation Edition）x86_64
• Firefox版本：106.0.1（64位），路径验证命令：

  [bans@bans-note ~]$ which firefox
  /usr/bin/firefox 
  

  文件存在验证：

  [bans@bans-note ~]$ ls /usr/bin |grep firefox
  firefox
  

  浏览器可正常启动：

  [bans@bans-note bin]$ ./firefox
  

Driver初始化代码片段 #

case "linux_firefox":{
    System.setProperty("webdriver.gecko.driver", PATH_LINUX_FIREFOX_DRIVER);
    System.setProperty("webdriver.firefox.bin", PATH_LINUX_FIREFOX);
    FirefoxOptions firefoxOptions = new FirefoxOptions();
    firefoxOptions.addArguments("--headless");
    firefoxOptions.addArguments("--no-sandbox");
    driver = new FirefoxDriver();

    break;
}

注：PATH_LINUX_FIREFOX_DRIVER和PATH_LINUX_FIREFOX均指向已确认存在的对应文件路径

报错信息 #

已尝试无效的方案 #

• 修改Driver初始化代码，改用FirefoxBinary和DesiredCapabilities配置
• 重新安装Firefox
• 安装Firefox snap版本

解决方案 #

1. 确认Firefox真实二进制路径 #

Fedora下/usr/bin/firefox通常是软链接，并非真实二进制文件。执行以下命令查看真实路径：

ls -l /usr/bin/firefox

示例输出：lrwxrwxrwx. 1 root root 29 Oct 12 09:45 /usr/bin/firefox -> /usr/lib64/firefox/firefox，此时真实路径为/usr/lib64/firefox/firefox。

2. 调整初始化代码，指定真实路径 #

统一使用FirefoxOptions配置，避免混用系统属性，同时添加Linux下常见的参数：

case "linux_firefox":{
    System.setProperty("webdriver.gecko.driver", PATH_LINUX_FIREFOX_DRIVER);
    FirefoxOptions firefoxOptions = new FirefoxOptions();
    // 替换为上一步获取的真实Firefox二进制路径
    firefoxOptions.setBinary("/usr/lib64/firefox/firefox");
    firefoxOptions.addArguments("--headless");
    firefoxOptions.addArguments("--no-sandbox");
    firefoxOptions.addArguments("--disable-dev-shm-usage"); // 解决共享内存不足问题
    driver = new FirefoxDriver(firefoxOptions);
    break;
}

3. 验证权限 #

确保运行测试的用户对Geckodriver和Firefox二进制文件有执行权限：

chmod +x PATH_LINUX_FIREFOX_DRIVER
chmod +x /usr/lib64/firefox/firefox

4. 检查Geckodriver版本兼容性 #

Firefox 106需要搭配Geckodriver 0.31.0及以上版本，如果版本不匹配，下载对应版本替换即可。
