我有一个带有一个集线器和5个节点的selenium网格设置。他们都使用相同版本的selenium服务器2.41.0。
在节点上，已经有与chlenium服务器相同的文件夹中的chromedriver设置。
现在的任务是更新chromedriver而不破坏任何现有的jenkins测试。
我尝试过手动转到每个节点并更新chromedriver文件。但是，对jenkins的测试会抛出WebDriverException，说无法创建驱动程序。
这可能是什么问题？

答案 0 :(得分：0)
问题是驱动程序的实例是在主机上创建的（使用现有的chromdriver文件）。显然，一旦你替换更新的chrome驱动程序文件（较新版本）旧版本 - ＆gt;驱动程序实例重新初始化后，一切都应该正常工作。 要初始化驱动程序，我正在使用以下 java 代码：
public static WebDriver driverSetUp(WebDriver driver) throws MalformedURLException {
DesiredCapabilities capability = DesiredCapabilities.chrome();
log.info("Google chrome is selected");
System.setProperty("webdriver.chrome.driver", "....path/chromedriver.exe");
capability.setBrowserName("chrome");
capability.setPlatform(org.openqa.selenium.Platform.WINDOWS);
String webDriverURL = "http://" + environmentData.getHubIP() + ":" + environmentData.getHubPort() + "/wd/hub";
driver = new RemoteWebDriver(new URL(webDriverURL), capability);
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);
driver.manage().window().setSize(new Dimension(1920, 1080));
return driver;
}
尝试一下，让我们知道问题是否仍然存在。感谢。
