What best defines "continuous integration" in software development?

Continuous integration is best defined as a practice where developers frequently integrate code changes in a shared repository. This approach emphasizes the importance of merging code regularly, typically several times a day, to avoid integration issues that can arise when changes are left unmerged for extended periods. By integrating code frequently, teams can quickly identify and address any conflicts or errors that occur, leading to improved collaboration, faster feedback loops, and a more efficient development process.

This practice often involves automated testing, ensuring that each integration maintains the integrity of the codebase and that any introduced defects are promptly detected. The essence of continuous integration lies in fostering a disciplined environment that supports seamless collaboration among developers, ultimately enhancing both code quality and delivery speed.
