Continuous Integration can help to find integration issues earlier and to visualize the status of the build to all involved. Integration problems can be detected at build-time in stead of run-time during testing and teams can get immediate feedback on changes that they made and on the impact on components that are developed by other teams.
Oftentimes, complex software projects span across multiple repositories on account of external dependencies. This can be a challenge in itself, explains Google WebRTC engineer Patrik Höglund, who also described Google's approach to developing software that uses dozens of third-party libraries such as Chrome.
An interview with Yaniv Yehuda, Co-Founder and CTO of DBmaestro, about how they are doing agile development and using DevOps, how they implemented continuous delivery, on agile practices that turned out to be difficult to implement, and the benefits that they are getting for using agile and DevOps practices.
At Unruly teams have been applying eXtreme Programming (XP) since being founded in 2006. Teams take a test-first approach to developing code and invest in automated checks that can be run in live environments. InfoQ interviewed Rachel Davies about the importance of a continuous approach to testing, how this has evolved over the years and the business advantage that it delivers to Unruly.
Behavior driven development (BDD) can be used to improve communication between testers, developers and the business. For example you can use given-when-then scenarios to develop test scripts and at the same time define the requirements of the system. BDD involves all team members and helps them to think about the product.
DevOps Days Ljubljana 2015 took place on the 3rd and 4th April and talks covered the full CAMS spectrum: Culture, Automation, Measurement and Sharing.
Convinced that “whatever can be unit tested should be unit tested”, Mona El Mahdy, a Software Engineer in Test at Google, has written a blog post proposing several approaches to perform unit tests on the user interface of Android applications.

InfoQ interviewed Achtziger about continuous testing and continuous integration, infrastructural and social challenges with continuous testing, testing processes and tools, and improving continuous testing.
The state of testing survey 2015 aims to provide insight in the adoption of test techniques and practices, test automation, and the challenges that testers are facing. Ongoing developments have impact on testing, such as the Internet of Things (IoT) and the adoption of agile where developers and testers collaborate in teams and competencies become more important than roles and titles.
In a blog post on bad code and technical debt Steve Freeman described how Chris Matts came up with the metaphor of an unhedged call option for bad code. This post is being intensively discussed on Reddit and on Hacker News recently. InfoQ interviewed Steve and Chris about using metaphors for bad code and code smells, trade-offs and costs of low quality code, and responsibilities for code quality.
Netflix's Failure Injection Testing bridges the gap between isolated testing and unmitigated chaos testing by controlling the impact of the test. FIT establishes a context which other components of Netflix's production testing and infrastructure systems interpret and adjust the behavior of the system accordingly.
