What is Continuous Integration and why is it needed?

Continuous Integration (CI) is a software development practice where code changes are automatically built, tested, and integrated into a shared codebase regularly.

Why CI is needed:

• Early bug detection — automated tests run with each change, allowing quick identification and fixing of bugs.
• Reduction of integration problems — frequent integration prevents conflicts and complexities during merging.
• Improved code quality — automation of checks and tests helps maintain high standards.
• Faster development — developers receive quick feedback, speeding up the development cycle.

Example of a simple CI process:

1. Developer pushes changes to the repository.
2. CI server automatically runs build and tests.
3. On success, changes are integrated into the main branch.
4. On errors, the developer receives a notification for correction.

This is the foundation of modern DevOps and Agile processes.
