Question

我想使用docker启动Selenium环境，并使用我的本地mac进行e2e测试。

如果是当前在docker环境中创建的Selenium，则测试将通过，但Chrome浏览器将无法启动。

如果＆＃34; selenium-standalone开始＆＃34;在我的本地mac中完成，chrome将启动。

有人告诉我，如果使用docker构建时没有启动chrome的原因吗？

复制程序如下

启动泊坞广告

docker run -i -t -p 4444:4444 --rm --name e2e-test  selenium/standalone-chrome:3.1.0

本地使用npm install webdriverio

$ mkdir -p webdriverio-test
$ cd webdriverio-test
$ npm install webdriverio --save-dev

执行＆＃34; wdio repl chrome＆＃34;

$ ./node_modules/.bin/wdio repl chrome

结果

$ ./node_modules/.bin/wdio repl chrome
[11:48:07]  DEBUG   Queue has stopped!
[11:48:07]  DEBUG   You can now go into the browser or use the command line as REPL
[11:48:07]  DEBUG   (To exit, press ^C again or type .exit)

chrome无法启动。

docker log＆＃34; ./ node_modules / .bin / wdio repl chrome＆＃34;执行

$ ./node_modules/.bin/wdio repl chrome

chrome启动的过程如下

安装selenium-standalone并在本地mac中启动selenium-standalone。

$ npm install selenium-standalone@latest -g
$ selenium-standalone install

$ selenium-standalone start

执行＆＃34; wdio repl chrome＆＃34;

$ ./node_modules/.bin/wdio repl chrome

结果

chrome将启动

selenium-standalone log＆＃34; ./ node_modules / .bin / wdio repl chrome＆＃34;执行

services:
  selenium-hub:
    image: selenium/hub
    container_name: selenium-hub
    ports:
      - "4444:4444"
  chrome:
    image: selenium/node-chrome
    container_name: chrome
    depends_on:
      - selenium-hub
    environment:
      - HUB_HOST=selenium-hub
      - HUB_PORT=4444
      - JAVA_OPTS=-Dwebdriver.chrome.whitelistedIps=

Answer 2

将docker容器视为远程selenium。在您的代码中，您必须使用RemoteWebDriver并使用4444端口连接它。 Chrome将在容器内运行而没有图形反馈（您将看不到Chrome正在运行）
