java – WebDriverException：未知错误：无法将窗口状态更改为最大化,当前状态正常,MAC OS X上的Chrome 70和Chromedriver 2.43

我们使用的是Chrome版本70.0.3538.67(官方版本)(64位),ChromeDriver 2.43.600229. Chrome窗口出现,但网址停留在“data：,”. (下面的堆栈跟踪)

我们找到了使用Chrome版本69 w / chromedriver 2.43的解决方案,但Chrome仍然坚持要更新自己.

我们运行Selenium-java 3.4,htmlunit-driver 2.27,testng 6.9.4,junit 4.7 with maven-compiler-plugin 3.6.1,maven-surefire-plugin 2.22.0.

解决方法

此错误消息…

org.openqa.selenium.WebDriverException: unknown error: failed to change window state to maximized,current state is normal

…暗示ChromeDriver无法最大化Chrome浏览器客户端的窗口状态.

Buggy Mac OSX ChromeDriver取代了

Chrome版本70发布后,有些人报告说使用ChromeDriver最大化Mac上的浏览器窗口不再有效. ChromeDriver团队已调查此问题,并为其创建了修复程序. ChromeDriver构建版本现已在以下位置提供：

>如果您使用的是Chrome版本70(当前的稳定版本),请从https://chromedriver.storage.googleapis.com/index.html?path=70.0.3538.97/下载ChromeDriver版本70.0.3538.97
>如果您使用的是Chrome版本71(当前测试版),请从https://chromedriver.storage.googleapis.com/index.html?path=71.0.3578.33/下载ChromeDriver版本71.0.3578.33

ChromeDriver发布电子邮件快照

但是,您的主要问题是您使用的二进制文件版本之间不兼容,如下所示：

>您的JDK版本是1.8.0_131,这是非常古老的.

>将JDK升级到最近的级别JDK 8u181.

>您的Selenium客户端版本是3.4.0,差不多一年了.

>将Selenium升级到当前级别Version 3.14.0.

从另一个角度来看,这个问题看起来像是从Feature request : ChromeDriver to support window resizing over a remote connection开始的回归问题.

Release Notes中的ChromeDriver v2.43明确提到：

ChromeDriver to support window resizing over a remote connection

但是,根据最大化Chrome浏览器客户端的最佳做法,建议使用ChromeOptions类,如下所示：

System.setProperty("webdriver.chrome.driver","C:\\your_directory\\chromedriver.exe");
ChromeOptions opt = new ChromeOptions();
opt.addArguments("disable-infobars");
opt.addArguments("--start-maximized");
opt.addArguments("--disable-extensions");
WebDriver driver = new ChromeDriver(opt);
driver.get("https://google.com");

参考

您可以在driver.manage().window().maximize() issue with ChromeDriver 2.33找到详细的讨论

更新(2018年11月20日)

> ChromeDriver 2.44已发布.> ChromeDriver 2.44支持Chrome版本69到71>此版本与ChromeDriver 2.43类似,但还有其他错误修复.>支持chrome 72.x的ChromeDriver预计将于12月初发布.
