Spot defects early with Continuous Integration
Continuous Integration (or CI) is a process that consists of continuously compiling, testing, inspecting, and deploying source code. In many Continuous Integration environments, this means running a new build anytime code within a source code management repository changes. The benefit of CI is simple: assembling software often greatly increases the likelihood that you will spot defects early, when they still are relatively manageable. In this tutorial, a companion to his series In pursuit of code quality, Andrew Glover introduces the fundamental aspects of Continuous Integration and steps you through how to set up a CI process using best-of-breed open source technologies.
