推荐答案

这个错误信息...

org.openqa.selenium.WebDriverException: disconnected: not connected to DevTools
  (Session info: chrome=79.0.3945.117)
.

Capabilities {acceptInsecureCerts: false, browserName: chrome, browserVersion: 79.0.3945.117, chrome: {chromedriverVersion: 78.0.3904.70 (edb9c9f3de024..., userDataDir: /var/folders/mz/2_llwtkx31d...}, goog:chromeOptions: {debuggerAddress: localhost:54446}, javascriptEnabled: true, networkConnectionEnabled: false, pageLoadStrategy: normal, platform: MAC, platformName: MAC, proxy: Proxy(), setWindowRect: true, strictFileInteractability: false, timeouts: {implicit: 0, pageLoad: 300000, script: 30000}, unhandledPromptBehavior: dismiss and notify}

...暗示 ChromeDriver 无法启动/生成新的浏览上下文，即 Chrome 浏览器 会话.

...implies that the ChromeDriver was unable to initiate/spawn a new Browsing Context i.e. Chrome Browser session.

您的主要问题是您使用的二进制文件版本之间的不兼容性，如下所示:

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• 您正在使用 chromedriver=78.0
• chromedriver=78.0的发行说明a> 明确提及以下内容:

支持 Chrome v78

• 您正在使用 chrome=79.0
• ChromeDriver v79.0的发行说明/a> 明确提及以下内容:
• You are using chrome=79.0
• Release Notes of ChromeDriver v79.0 clearly mentions the following :

支持 Chrome 79

所以 ChromeDriver v78.0 和 Chrome 浏览器 v79.0

确保:

• ChromeDriver 已更新为当前 ChromeDriver v79.0.3945.36 级别.
• Chrome 已更新至当前 Chrome 版本 79.0 级别.(根据 ChromeDriver v79.0 发行说明)
• 清理你的项目工作区通过你的IDE和重建你的项目只需要依赖.
• 如果您的基本 Web 客户端 版本太旧，请卸载它并安装最新的 GA 和发布版本的 Web 客户端.
• 进行一次系统重启.
• 以 非 root 用户身份执行您的 @Test.
• 总是在 tearDown(){} 方法中调用 driver.quit() 来关闭 &优雅地销毁 WebDriver 和 Web Client 实例.
• ChromeDriver is updated to current ChromeDriver v79.0.3945.36 level.
• Chrome is updated to current Chrome Version 79.0 level. (as per ChromeDriver v79.0 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• If your base Web Client version is too old, then uninstall it and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your @Test as non-root user.
• Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
