We use state-of-the art CI servers such as Jenkins and TravisCI at the heart of our software development process, as well as in our open source projects.
CI is a software engineering practice that encourages every member of a team to integrate their work frequently. Doing so increases the chance of finding defects quickly and eliminating them. Automated build and automated testing at each integration point ensures reduced integration problems and enables cohesive software development. Properly implemented CI approach will allow rapid delivery of your software.
