我已签入代码；没有使用 driver.close() 或 driver.quit().测试有时会成功运行，有时会失败.

I have checked in code; there is no driver.close() or driver.quit() is used.Tests are running successfully sometime and sometimes are failing.

谁能帮我解决这个问题?

Can any one help me for this issue?

推荐答案

这个错误信息...

org.openqa.selenium.NoSuchSessionException: no such session

...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=2.38
• chromedriver=2.38 的发行说明明确提及以下内容:

支持 Chrome v65-67

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

支持Chrome 79版

• 您的 Selenium Client 版本是 2018-02-07T22:25:02.294Z 的 3.9.1，几乎是 2 岁.
• 您的 JDK 版本 是 1.8.0_121，非常古老.
• Your Selenium Client version is 3.9.1 of 2018-02-07T22:25:02.294Z which is almost 2 years older.
• Your JDK version is 1.8.0_121 which is pretty ancient.

所以 JDK v8u121、Selenium Client v3.9.1、ChromeDriver v2.38 和 Chrome 之间存在明显的不匹配浏览器 v79.0

确保:

• JDK 升级到当前级别 JDK 8u232.
• Selenium 已升级到当前级别版本 3.141.59.
• 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.
• 如果您的基础 Web Client 版本太旧，请通过 卸载它Revo Uninstaller 并安装最新的 GA 和发布版本的 Web Client.
• 进行一次系统重启.
• 以 非 root 用户身份执行您的 @Test.
• JDK is upgraded to current levels JDK 8u232.
• Selenium is upgraded to current levels Version 3.141.59.
• 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 through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your @Test as non-root user.
