A software development practice where developers frequently merge their code changes into a shared repository, often multiple times a day. Each integration triggers an automated process that builds the application and runs tests to verify that the new code does not introduce errors. By catching bugs and integration issues early, CI helps maintain a stable codebase and reduces the risk of costly problems later in the development cycle. Common CI tools include Jenkins, GitHub Actions, and GitLab CI, which automate the testing and validation of code with every commit.
