Question

我试图在Docker上运行pytest测试框架。但是在运行容器时遇到以下错误。

driver.maximize_window()

有人可以建议这里缺少什么吗？在Docker容器中运行Selenium-pytest UI自动化框架是否需要其他配置？

注意＃为了创建图像，请先使用docker-compose up，然后再创建容器docker-compose run test sh

Answer 1

我通过使用docker-compose创建并联网多个容器解决了此问题。为此，我使用了docker-compose.yaml创建了容器，并分别使用dockerfile和pytest.dockerfile来管理本地文件和pytest

我已附上以下文件

version: '3.7'
services:
  selenium:
    image: selenium/hub
    ports:
      - 4444:4444
      - 5901:5900
  chrome:
    image: selenium/node-chrome-debug
    depends_on:
      - selenium
    environment:
      - HUB_HOST=selenium
  test:
    volumes:
      - .:/myapp
    build: 
      context: .
      dockerfile: pytest.dockerfile

docker-compose.yaml

FROM python:3.7-alpine
