Internet Explorer特定的错误量角器

Question

有人可以帮助我确定这是什么错误。我的所有测试用例都在Chrome和IE中传递我在getText（）上得到这样的随机错误，我不明白它是什么。

应该比较检查总回复消息：WebDriverError：无法确定类型来自：E。最后1个字符读取：E构建信息：版本：'3.14.0'，修订版：'aacccce0'，时间：'2018-08-02T20：13 ：22.693Z'系统信息：os.name：'Windows 10'，os.arch：'amd64'，os.version：'10 .0'，java.version：'10 .0.1'驱动程序信息：driver.version：unknown Stack ：WebDriverError：无法确定类型：E。最后1个字符读取：E构建信息：版本：'3.14.0'，修订版：'aacccce0'，时间：'2018-08-02T20：13：22.693Z'系统信息：os.name：'Windows 10'，os.arch：'amd64'，os.version：'10 .0'，java.version：'10 .0.1'驱动程序信息：driver.version：unknown

Answer 1

根据此异常，您尝试通过xpath查找元素时测试失败：

WebDriver.findElements(By(xpath, //qms-percentage-widget//div[@id='F2']//div[@class='default-widget']))
