Can you explain the principle of CI/CD and its advantages in software development?

CI/CD (Continuous Integration / Continuous Delivery) is a practice of automating the processes of building, testing, and deploying software.

How it works:

• CI (Continuous Integration): developers regularly (often several times a day) integrate changes into a shared repository. Each commit is automatically built and tested, allowing quick detection of errors.
• CD (Continuous Delivery/Deployment): after successful testing, changes are automatically prepared for release and can be quickly deployed to production or staging environments.

Advantages:

• Fast detection and correction of errors
• Improved code quality through automated tests
• Accelerated release of new features
• Reduced risk during releases through automation

Example: when a push is made to the repository, a pipeline is triggered that builds the project, runs tests, and if successful, deploys the application to a test server.
