CI, or Continuous Integration, is a software development practice where developers frequently integrate their code changes into a shared repository. Each integration is automatically tested to detect errors quickly, allowing teams to identify and fix issues early in the development process. This approach helps maintain code quality and reduces integration problems. The main goal of CI is to improve software development efficiency and collaboration among team members. By automating testing and integration, developers can focus on writing code rather than spending time on manual integration tasks. This leads to faster delivery of features and a more reliable software product.
