CI/CD stands for Continuous Integration and Continuous Delivery/Deployment — practices that automate building, testing, and deploying software. The goal is to release changes frequently, reliably, and quickly, with automation replacing manual, error-prone processes.
CI — Continuous Integration
CONTINUOUS INTEGRATION: developers frequently merge code into a shared branch, and each
change is AUTOMATICALLY built and tested:
→ on every push/PR: build the code + run tests (automatically)
→ catch integration problems and bugs EARLY (immediately, not weeks later)
→ keep the main branch in a working state
→ Frequent integration + automated verification = fewer, smaller, easier-to-fix problems.
