继续获取SessionNotCreatedException：无法创建新服务：ChromeDriverService错误

标签： java selenium-webdriver selenium-chromedriver selenium-grid2

不管我尝试什么；最新的chrome浏览器，最新的chromedriver，最新的selenium服务器等，但是当我在Mac OSX上运行测试时，我始终收到上述错误。我看过其他类似的问题，甚至尝试了那里提出的解决方案，但似乎没有任何解决方案。我想念什么或做错什么了？

这是我的设置：

  • Chrome版本：75.0.3770.100（最新版本）
  • Chromedriver版本：75.0.3770.90也尝试了76
  • Selenium Server独立版本：3.141.59
  • Java JDK版本：1.8.0_131

我正在按照以下步骤初始化集线器和节点

集线器：     java -jar selenium-server-standalone-3.141.59.jar -role hub -port 9999

节点：     java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://localhost:9999/grid/register

这是我初始化remoteWebDriver实例的方式。

String absolutePath = Config.TEST_RESOURCES_PATH;
        if(Platform.isWin()){
        absolutePath = absolutePath + "chromedriver.exe"; // "C:\user\...\src\test\resources\chromedriver.exe"
        } else if (Platform.isMac()){
        absolutePath = absolutePath + "chromedriver";// "/Users/.../src/test/resources/chromedriver"
        }

        System.setProperty("webdriver.chrome.driver", absolutePath);
        ChromeOptions cap = new ChromeOptions();
        cap.setCapability(CapabilityType.TAKES_SCREENSHOT, true);
        String url = "http://" + Config.MACHINE_IP + ":" + Config.WEB_PORT_NUMBER + "/wd/hub";
        try {
            DriverAgent.setWebDriver(new RemoteWebDriver(new URL(url), cap));
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }

当我在Windows 10机器上运行此代码时，它可以很好地工作，即打开浏览器并且测试运行顺利；但是，在Mac机器上，它始终失败，并显示以下堆栈跟踪消息

更改您的node命令，使其看起来像这样，并指定chromedriver.exe的路径和一个配置该节点上可用插槽的config.json文件：

 java -Dwebdriver.chrome.driver="C:\Users\xxxx\Documents\Browsers\ChromeDirectory\chromedriver.exe" -jar selenium-server-standalone-3.141.59.jar -role node -hub "http://XX.XXX.XX.XXX:4444/grid/register/" -nodeConfig config.json
