continuous integration

For decades-with the exception of agile-dev followers-the IT community has continued to build and protect its departmental silos. Project management, business analysis, development, testing, DB administration, and operations are just a few of the specializations that are carved out and institutionalized. Agile practices seek to eliminate the walls and empower people to deliver the highest value to the business. DevOps is the latest effort in this direction-bringing developers, testers, and operations together to replace their silos with a continuous collaboration pipeline. Paul Peissner introduces DevOps and explains how it is a key to transitioning from continuous integration (creating the finished software product immediately) to continuous delivery (making the product immediately available to users) and adding tremendous new business value.

Continuous integration (CI) has become a buzzword, with most engineering organizations claiming they've adopted the practice. However, the sad truth is that unreliable tests, long feedback loops, and poor configuration management block their efforts and minimize CI's potential benefits. Jesse Dowdle shares how AtTask radically redesigned its engineering pipeline and, through massive CI scaling, drove three days of testing to just minutes. Learn the pros and cons of different CI systems and how to integrate them with the cloud. Watch a live demo of AtTask's internal test and CI systems, which they’ve designed to make "Every commit a potential release candidate"-meaning that every commit is an iteration. Arm yourself with the talking points to sell massive CI to executives.

Jesse Dowdle sat down with us recently to discuss the benefits that embracing "massive" continuous integration and deployment brings to testing. Jesse is presenting the session "Massive Continuous Integration and Light Speed Iterations" at the 2012 Better Software Conference East.

Developers must have good feedback to ensure productivity. Most shops have a continuous integration (CI) build process that allows the developer to quickly know if a build failed, and some shops have an automatic deploy of the CI build to provide website feedback. Lance Lyons writes about an approach to automating the update of databases in a CI environment.
