运行 Selenium 测试中的 chromium 与 chromium-browser

Question

我试图运行在 Docker 中进行一些 Selenium 测试。我从 ubuntu:bionic 移动到 bitnami:jessie，我发现 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，然后在运行ning Protractor 测试时出现以下错误。

Answer 1

你的 chromium 版本是多少？

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

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

如果您的 chromedriver 年龄较大：

a) 更新它或者，

b) 降级 chromedriver
