A Build Pipeline is a series of automated processes that build, test, and deploy code. It orchestrates the steps required to compile source code, run automated tests, and package the software for deployment. Build pipelines are an essential part of CI/CD practices, ensuring that code changes are continuously integrated, tested, and delivered to production environments. Tools like Jenkins, Azure Pipelines, GitLab CI/CD, and CircleCI are commonly used to create and manage build pipelines. By automating these processes, build pipelines help reduce manual errors, speed up release cycles, and improve software quality.
