Selenium2学习-037-WebUI自动化实战实例-IE浏览器显示比例问题：org.openqa.selenium.remote.SessionNotFoundException: Unexpected error launching Internet Explorer. Browser zoom level was set to 94%. It should be set to 100%

好久没有写博文了，今天在给部门新人演示 Selenium WebDriver 启动其支持的各种浏览器时，启动 IE 时总是无法打开对应的百度网址，页面如下所示：

控制台及日志显示的错误信息如下所示：

　　经由日志错误提示信息可知，是因为浏览器窗口大小比例的问题，重新设置显示比例为 100%，设置方法如下图所示：

　　

重新运行脚本即可通过。

 

至此，WebUI 自动化功能测试脚本第 037-IE 浏览器显示比例问题：org.openqa.selenium.remote.SessionNotFoundException: Unexpected error launching Internet Explorer. Browser zoom level was set to 94%. It should be set to 100% 顺利完结，希望此文能够给初学 Selenium 的您一份参考。

最后，非常感谢亲的驻足，希望此文能对亲有所帮助。热烈欢迎亲一起探讨，共同进步。非常感谢！ ^_^
