我是Selenium的新手,需要一些跟踪来查找以下错误的根本原因.

Answer 1

错误说明了一切:

org.openqa.selenium.WebDriverException: unknown error: cannot determine loading status
from unknown error: missing or invalid 'entry.level'

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=2.29.461591
• 发行说明chromedriver=2.29.461591明确提到以下内容:

Supports Chrome v56-58

• 您正在使用 chrome=63.x
• 发行说明ChromeDriver v2.34明确提到以下内容:

Supports Chrome v61-63

• 发行说明ChromeDriver v2.35明确提到以下内容:

Supports Chrome v62-64

• 你正在使用Selenium Version 3.5.3.
• 你JDK version是1.8.0_131.

因此,chromedriver版本(v2.29.4)[支持Chrome v56-58 ]与Chrome浏览器版本(v63.x)[由ChromeDriver v2.34最低支持] 之间明显不匹配

解

• 升级JDK到最近的水平JDK Version 8 Update 151.
• 升级Selenium到当前级别Version 3.8.1.
• 升级ChromeDriver到 ChromeDriver v2.35水平.

• 保持Chrome到 Chrome v64.x水平.(as per ChromeDriver v2.35 release notes)

• 执行你的Test.
