您的主要问题是所使用的二进制文件版本之间的不兼容性:

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>明确提到以下内容:

支持 Chrome v78

• 您正在使用 chrome = 79.0
• ChromeDriver v79.0 明确提到以下内容:

支持 Chrome 79

因此 ChromeDriver v78.0 与 Chrome浏览器v79.0

确保:

• ChromeDriver 已更新为当前的ChromeDriver v79.0.3945.36 级别.
• Chrome 已更新为当前的 Chrome版本79.0 级别.(根据 ChromeDriver v79.0发行说明)
通过 IDE
• 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
• 如果您的基本 Web客户端版本太旧，则将其卸载并安装最新版本的 Web客户端 GA.
• 进行系统重启.
• 以非root用户用户的身份执行 @Test .
• 始终在 tearDown(){} 方法中调用 driver.quit()以关闭&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.
