🚀 Get the full step-by-step project guide here: https://learn.nextwork.org/projects/ai-cicd-github Welcome to the AI x GitHub Actions Series! Today you’ll build your first CI pipeline that automatically runs Python tests with pytest on every push to main. You’ll learn how teams at GitHub, Shopify, and Stripe catch bugs before they ever hit production by wiring your repo into a real-world CI workflow. What you’ll learn today: ✅ Fork and clone a real-world starter repository ✅ Set up a Python virtual environment and install dependencies with requirements.txt ✅ Write functions and unit tests using pytest ✅ Create a GitHub Actions workflow that runs on every push and pull request ✅ Break a test on purpose and watch CI catch the failure ✅ Fix the test and verify your pipeline goes green again 🧰 Related Projects Your First GitHub Actions AI Workflow (You’re here!) – https://learn.nextwork.org/projects/ai-cicd-github Coming Soon – AI Code Review on Every PR Coming Soon – Advanced AI CI Workflows Coming Soon – Full GitHub Actions DevOps Track ⏱️ TIMESTAMPS 0:00 – Intro & project overview 0:30 – Why CI/CD matters (concepts & benefits) 2:00 – Architecture diagram & what you’ll build 3:15 – Step 0: Before we start (project goals) 4:20 – What we’re building: CI/CD pipeline 4:45 – Step 1 intro: Set up your Python project 6:00 – Forking and cloning the starter repo 7:50 – Opening the project in Cursor 9:40 – Creating a Python virtual environment 10:25 – Activating the virtual environment 12:45 – Installing requirements (pytest, build, etc.) 13:20 – Exploring the project structure & key files 15:30 – Step 2 intro: Write code and tests with pytest 17:15 – What is a Python function?
