WebDriverThread.getDriver（）-在将Selenium作为systemctl服务启动时创建驱动程序错误

标签： selenium google-chrome selenium-webdriver selenium-chromedriver systemctl

以下是我的JSON文件chrome节点：

{
  "capabilities":
  [
    {
      "webdriver.chrome.driver": "/home/node1/seleniumserver/chromedriver",
      "browserName": "chrome",
      "maxInstances": 5,
      "seleniumProtocol": "WebDriver",
      "version": 2.39,
      "deviceName": "chrome"
    }
  ],
  "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
  "maxSession": 100,
  "timeout": 1500,
  "port": 4502,
  "host": "10.28.19.104",
  "register": true,
  "registerCycle": 5000,
  "hub": "http://10.28.19.251:4545",
  "nodeStatusCheckTimeout": 5000,
  "nodePolling": 5000,
  "role": "node",
  "unregisterIfStillDownAfter": 60000,
  "downPollingLimit": 2,
  "debug": false,
  "servlets" : [],
  "withoutServlets": [],
  "custom": {}
}

下面是我的启动脚本：

java -jar /home/node1/seleniumserver/selenium-server-standalone-3.141.59.jar -role node -nodeConfig /home/node1/seleniumserver/nodeConfigChrome.json

我正在尝试使用systemctl创建服务。我按照以下步骤操作：

1）在/ etc / systemd / system文件夹中创建了selenium.service。

After=network.target
StartLimitIntervalSec=0

[Service]
Type=simple
RestartSec=1
User=node1
ExecStart=/usr/bin/env sh /home/node1/seleniumserver/startNodeChrome.sh

[Install]
WantedBy=multi-user.target

2）systemctl守护程序重新加载 3）systemctl启动硒 4）systemctl启用硒。

服务已启动并成功运行。

但是当我从jenkins触发脚本时，出现此错误。从终端启动时，否则将正常工作。

此错误消息... 

com.ytlctest.base.WebDriverThread.getDriver() - Error creating the driver
org.openqa.selenium.SessionNotCreatedException: Unable to create new service: ChromeDriverService
.
Driver info: driver.version: unknown

...表示 ChromeDriver 无法启动/产生新的 WebBrowser ，即 Chrome浏览器会话。

您的主要问题是所使用的二进制版本之间的不兼容性：

  • 您正在使用 chromedriver = 2.39
  • chromedriver=2.39的发行说明中明确提到以下内容：
  

支持 Chrome v66-68

  • 大概您正在使用 chrome = 75.0
    • 的最新GA版本
  • ChromeDriver v75.0的发行说明中明确提到以下内容：
  

支持 Chrome v75

因此 ChromeDriver v2.39 与 Chrome浏览器v75.0

之间存在明显的不匹配

解决方案

  • 将 ChromeDriver 升级到当前的ChromeDriver v75.0级别。
  • 保持 Chrome 版本为 Chrome v75 级别。
    • 通过您的 IDE
  • 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项。
  • 如果您的基本 Web客户端版本过旧，请通过Revo Uninstaller进行卸载，并安装最新版本的 Web客户端。 li>
  • 以非root用户用户的身份执行@Test。
