Git and CI/CD: Implementing Automated Deployment and Testing with Git

This article introduces the core concepts of Git and CI/CD and their combined application. Git is a version control tool, like a "code diary," which records modifications, manages collaboration, and avoids conflicts and version chaos. CI/CD (Continuous Integration/Continuous Delivery/Deployment) replaces manual processes with automation, enabling automatic testing and deployment after code submission to improve efficiency. The combination of the two is a "golden partnership": developers commit code to a Git repository, and CI/CD tools automatically trigger processes such as testing, building, and deployment (e.g., deploying a frontend project to Netlify using GitHub Actions). The combined advantages are significant: reducing errors (through automated testing), accelerating iteration (completing the entire process in minutes), lowering costs (reducing manual labor), and facilitating traceability (enabling checks on deployment sources). Git lays the foundation for version management, while CI/CD enables process automation. Their combination transforms development from manual to smooth, making it an essential skill in modern development.
