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.
