在运行 Selenium 测试的情况下，铬与铬浏览器

Question

我试图在 Docker 中运行一些 Selenium 测试。我从ubuntu:bionic 移动到bitnami:jessie，发现chromium-browser 在bionic 中可用，chromium 在jessie 中可用。

这两个包有什么区别？如果我安装chromium，那么在运行量角器测试时会出现以下错误。

Answer 1

你的铬版本是什么？

在这里你可以看到类似的问题：Chromedriver Devtools port number error

现在您正在使用chromedriver 2.46.628388。支持chrome v71-v73 (http://chromedriver.chromium.org/downloads)

如果您的 chromedriver 较旧：

a) 更新它，或者，

b) 降级 chromedriver
