我曾尝试为gitlab托管的个人项目设置pytest管道CI/CD。
我试着用两个基本文件建立一个简单的项目：
文件test_core.py，为了简单起见，不包含任何其他依赖项：
# coding: utf-8
# !/usr/bin/python3
import pytest
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.options import Options
def test_basic_headless_selenium_example():
"""Test selenium installation by opening python website.
(inspired by https://selenium-python.readthedocs.io/getting-started.html)
"""
opts = Options()
opts.headless = True
driver = webdriver.Firefox(options=opts)
driver.get("http://www.python.org")
driver.close()
文件.gitlab-ci.yml，用于CI/CD自动测试：
stages:
- tests
pytest:python3.7:
image: python:3.7
stage: tests
services:
- selenium/standalone-firefox:latest
script:
# - apt-get update && apt-get upgrade --assume-yes
- wget -O ~/FirefoxSetup.tar.bz2 "https://download.mozilla.org/?product=firefox-latest&os=linux64"
- tar xjf ~/FirefoxSetup.tar.bz2 -C /opt/
- ln -s /opt/firefox/firefox /usr/lib/firefox
- export PATH=$PATH:/opt/firefox/
- wget -O ~/geckodriver.tar.gz "https://github.com/mozilla/geckodriver/releases/download/v0.28.0/geckodriver-v0.28.0-linux64.tar.gz"
- tar -zxvf ~/geckodriver.tar.gz -C /opt/
- export PATH=$PATH:/opt/
- pip install selenium pytest
- pytest
在我的笔记本电脑上，pytest命令100%正常工作。当我向gitlab推送提交时，我会错误：
> raise exception_class(message, screen, stacktrace)
E selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 255

我创建了一个简单的项目：https://gitlab.com/OlivierLuG/selenium_firefox它们再现了这个例子。故障管道可以直接在此处找到：https://gitlab.com/OlivierLuG/selenium_firefox/-/pipelines/225711127
有人知道如何修复这个错误吗？
我终于用下面的.gitlab-ci.yml文件在绿色上ping到了gitlab CI。
请注意，我不喜欢yaml语言。为了缩短文件，我使用了一个名为install_firefox_geckodriver的共享代码块。然后，我用python 3.7和3.8配置了两个作业，它们调用这个块。使这种测试发挥作用的关键是：_在无头模式下运行(对我来说已经是这样了(_使用命令行安装firefox和geckodriver_安装firefox依赖项_使用gitlab硒服务
这是我的yaml文件。成功的管道可以在这里找到：https://gitlab.com/OlivierLuG/selenium_firefox/-/pipelines/225756742

如果您使用的是基于Ubuntu的映像，安装过程可以简化为以下步骤，允许获得最后一个geckodriver版本：
before_script:
# Configura the timezone, needed for some libraries.
# Solution from https://dev.to/setevoy/docker-configure-tzdata-and-timezone-during-build-20bk
- TZ=America/Sao_Paulo # Numeric inputs: 2 - 134.
- ln -snf /usr/share/zoneinfo/$TZ /etc/localtime
- echo $TZ > /etc/timezone
# Add the needed libraries.
- apt update && apt -y upgrade
.install_firefox_geckodriver: &install_firefox_geckodriver
- apt -y install firefox curl wget # It needs timezone configuration made in "before_script"
#- wget -nv -O ~/FirefoxSetup.tar.bz2 "https://download.mozilla.org/?product=firefox-latest&os=linux64"
- wget $(curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest | grep 'browser_' | cut -d" -f4 | grep linux64.tar.gz$)
- tar -xf gecko*
