在Gitlab CI中运行selenium测试

Question

使用gitlab管道，我可以实现以下目标吗？

stages:
 - run-dvwa       # where I launch a web target using image of https://hub.docker.com/r/vulnerables/web-dvwa
 - run-selenium   # where I launch selenium using image selenium/standalone-firefox:latest
 - run-python     # where I run some py script to crawl dvwa end points

我可以按顺序运行上面的代码吗?这也意味着容器' run -dvwa‘和'run-selenium’在进入阶段'run-python‘时不能退出？

感谢您的建议或样品！

我的第一个版本(2021.07.26.v1)

python-test:
  services:
    - name: registry.gitlab.com/xxxx-yyy-demo/zzzzz-demo/dvwa-devops-demo
      alias: dvwa
      entrypoint: ["/main.sh"]
    - name: selenium/standalone-firefox:latest
      alias: selenium
  stage: run
  image: python:3
  script:
    - curl http://dvwa:80/login.php
    - curl http://selenium:4444/wd/hub
    - pip install selenium
    - python tests.py

我的test.py

driver = webdriver.Remote("http://selenium:4444/wd/hub", DesiredCapabilities.FIREFOX)
server = 'http://dvwa:80'
driver.get(server + '/login.php')

从我的测试来看，一切都通过了，直到driver.get(...)行，我得到了一个

Traceback (most recent call last):
  File "/builds/xxxx-yyy-demo/zzzzz-demo/dvwa-devops-demo/xxxx-yyy-demo/tests.py", line 42, in <module>
    driver.get(server + '/login.php')
  File "/usr/local/lib/python3.9/site-packages/selenium/webdriver/remote/webdriver.py", line 333, in get
    self.execute(Command.GET, {'url': url})
  File "/usr/local/lib/python3.9/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python3.9/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)

在GitLab CI中，阶段是按顺序执行的。仅当上一阶段成功完成时，才进入下一阶段。

您的用例听起来更像是您可以从services中获益，例如：

python-test:
  stage: test
  image: python:3
  variables:
    FF_NETWORK_PER_BUILD: 1
  services:
    - name: vulnerables/web-dvwa:latest
      alias: dvwa
    - name: selenium/standalone-firefox:latest
      alias: selenium
  before_script:
    - pip install selenium
  script:
    - python tests.py

请注意，您必须启用network per-build功能(FF_NETWORK_PER_BUILD feature flag)，以便selenium容器可以连接到dvwa容器。
