Build Secure Python Pipelines: Adding Tests and Hooks in Action

As we continue this series started in my Getting Started with Secure CI/CD: Essential Practices for Beginners post, I’ll be securing my Python code with automated testing and hooks. While some of this information builds on some previous posts I’ve created in the past, Adding pre-commit Hooks to Python Repo Writing Tests For Your Python Project I still wanted to incorporate these together in a meaningful way. My goal is to help anyone that is trying to figure out how to piece together their own pipeline. ...
