推荐答案

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)
Command duration or timeout: 2.03 seconds

Driver info: org.openqa.selenium.chrome.ChromeDriver

您的主要问题是您使用的二进制文件之间的版本兼容性，如下所示:

Your main issue is the version compatibility among the binaries you are using as follows :

• 您正在使用 chromedriver=2.31
• chromedriver=2.31的发行说明 明确提及以下内容:

• You are using chromedriver=2.31
• Release Notes of chromedriver=2.31 clearly mentions the following :

支持 Chrome v58-60

• 您正在使用 chrome=64.0
• ChromeDriver v2.35 的发行说明 明确提及以下内容:
• You are using chrome=64.0
• Release Notes of ChromeDriver v2.35 clearly mentions the following :

支持 Chrome v62-64

• 未检测到您的 Selenium Client，因此我们无法知道 Selenium Client 版本.
• 您的 JDK 版本 是 1.8.0_112，非常古老.

所以 JDK 版本、Selenium Client 版本、ChromeDriver 版本(v2.31em>) 和 Chrome 浏览器 版本 (v64.0)

So there is a clear mismatch between the JDK version , Selenium Client version , ChromeDriver version (v2.31) and the Chrome Browser version (v64.0)

• 将 JDK 升级到最新级别 JDK 版本 8 更新 151.
• 将 Selenium 升级到当前级别 Version 3.8.1.
• 将 ChromeDriver 升级到 ChromeDriver v2.35 级别.
• 将 Chrome 保持在 Chrome v64.x 级别.(根据 ChromeDriver v2.35 发行说明)
• 如果您的基础 Chrome 版本太旧，请通过 <卸载它em>Revo Uninstaller 并安装最新的 GA 和已发布版本的 Chrome.
• 执行您的测试.
• Upgrade JDK to recent levels JDK Version 8 Update 151.
• Upgrade Selenium to current levels Version 3.8.1.
• Upgrade ChromeDriver to ChromeDriver v2.35 level.
• Keep Chrome to Chrome v64.x levels. (as per ChromeDriver v2.35 release notes)
• If your base Chrome version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Chrome.
• Execute your Test.
