Answer 1

您应该更新到最新的ChromeDriver 2.33。希望它能解决您的问题。

Answer 2

错误说明了一切：

Exception in thread "main" org.openqa.selenium.WebDriverException: disconnected: unable to connect to renderer
  (Session info: chrome=64.0.3282.140)
  (Driver info: chromedriver=2.31.488763 (092de99f48a300323ecf8c2a4e2e7cab51de5ba8),platform=Windows NT 6.1.7601 SP1 x86) (WARNING: The server did not provide any stacktrace information)

您的主要问题是您所使用的二进制文件之间的版本兼容性，如下所示:

< li >您正在使用< code > chrome driver = 2.31 < Li > < code > chrome driver = 2.31 的发行说明明确提到了以下内容:

支持Chromev58-60

• 您正在使用铬 = 64.0
• Chrome驱动程序v2.35的发行说明明确提到了以下内容：

< code >支持Chrome v62-64

• 您的硒客户端未被检测到，因此我们无法知道硒客户端版本。
• 您的JDK版本是1.8.0_112，这是非常古老的。

因此，JDK版本，硒客户端版本，铬驱动程序版本（v2.31）和Chrome浏览器版本（v64.0）之间存在明显的不匹配。

• 将JDK升级到最新级别JDK Version 8 Update 151
• 将Selenium升级到当前版本
• 升级至ChromeDriver v2.35版本
• 保持Chrome至Chrome v64.xlevels。（根据ChromeDriver v2.35发行说明）
• 如果您的基本Chrome版本太旧，请通过Revo卸载程序卸载它，并安装最新的GA和Chrome发布版本
• 执行测试
