在GitLab CI中以情节方式运行破折号硒测试 [英] Running plotly dash selenium tests in gitlab CI

问题描述

所以我尝试在GitLab ci管道中实现Selenium测试。目前，我已经在本地系统上运行了这些测试，反映了管道中将要发生的测试方法，即我在本地系统上构建测试，然后尝试连接到Selenium/Standalone-Chrome实例以使用此命令运行测试

python3 -m pytest --junitxml=report.xml --log-cli-level DEBUG --webdriver Chrome --headless --remote-url http://localhost:4444/wd/hub testing/

这在我的本地计算机上运行正常。尝试使用GitLab-ci.yml

stages:
  - test

image: "python"

services:
  - selenium/standalone-chrome

test:
  stage: test
  tags:
    - docker
  services:
    - selenium/standalone-chrome:latest
  script:
    # Set environmental variables
    - DEV_DASHBOARD_CFG='./app/config.json'
    - apt-get update -qy
    - apt-get install -y xvfb zip wget ca-certificates
    - apt-get install -y libnss3-dev libasound2 libxss1 libappindicator3-1 libindicator7 gconf-service libgconf-2-4 libpango1.0-0 xdg-utils fonts-liberation libgbm1
    # Setup the application to run
    - apt-get install -y python-dev python-pip
    - pip install -r requirements.txt
    - cd app/
    - pwd
    - python3 -m pytest --junitxml=report.xml --log-cli-level DEBUG --webdriver Chrome -headless --remote-url http://selenium__standalone-chrome:4444/wd/hub testing/
  artifacts:
    when: always
    reports:
      junit: report.xml

我面临的这个问题是铬Web驱动程序似乎有错误。

推荐答案

您的GitLab运行者应该有权访问您尝试从GitLab CI运行的应用程序。根据错误，很明显GitLab Runner无法连接到应用程序URL。

所以请检查并确认GitLab运行者是否有权访问主机。
