Answer 1

我看到了同样的问题.只有在使用Chrome 65(目前:开发频道)时才会出现此问题.Chrome 64(稳定频道和测试版频道)一切正常.

事实证明我安装了一个旧的chromedriver.具体来说,我用chrome=65.0.3325.51用chromedriver=2.29.461585.将npm install -g chromedriver碰撞的chromedriver 运行到2.35.528157,现在问题解决了.希望这可以帮助!

TL; DR:跑npm install -g chromedriver

错误说明了一切:

Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: call function result missing 'value'

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:

• 您正在使用chromedriver = 2.33
• chromedriver发行说明= 2.33明确提到以下内容:

支持Chrome v60-62

• 您正在使用chrome = 65.0
• ChromeDriver v2.37的发行说明明确提到以下内容:

支持Chrome v64-66

因此,ChromeDriver版本(v2.33)与Chrome浏览器版本(v65.0)之间存在明显的不匹配

解

• 升级ChromeDriver当前ChromeDriver v2.37水平.
• 将Chrome版本保持在Chrome v65.x级别.(根据ChromeDriver v2.37发行说明)
• 清理你的项目工作,通过你的IDE和重建仅需要依赖你的项目.
• 使用CCleaner工具在执行测试套件之前和之后擦除所有操作系统.
• 如果您的基本Web客户端版本太旧,请通过Revo Uninstaller将其卸载并安装最新的GA和已发布的Web客户端版本.
• 执行你的@Test.
