Continuous Integration (CI) Principles and Practices

Developers integrate their code changes into a shared repository frequently, ensuring that the codebase is continuously evolving in a collaborative manner.

Every integration triggers an automated build process, including compiling the code, running tests, and creating executable artifacts. Automation ensures consistency and reliability.

A comprehensive suite of automated tests, including unit tests and integration tests, is run with each integration to detect and address issues early in the development process.

Developers receive immediate feedback on the success or failure of their code integration. Quick feedback allows for prompt issue resolution, reducing the risk of defects accumulating.

Use a version control system (e.g., Git) to manage code changes, enabling collaboration, tracking history, and providing a reliable mechanism for rollbacks.

Set up automated build processes triggered by code commits. These processes should compile the code, run tests, and produce deployable artifacts.

Develop and maintain a suite of automated tests to validate the correctness and functionality of the code. This includes unit tests, integration tests, and possibly end-to-end tests.

Employ a CI server (e.g., Jenkins, Travis CI) to automate the integration and testing process. The CI server monitors the version control system and triggers builds and tests upon code changes.
