Developing large software projects is a complicated task and can be demanding for developers. Continuous integration is common practice for reducing complexity. By integrating and testing changes often, changesets are kept small and therefore easily comprehensible. Travis CI is a service that offers continuous integration and continuous deployment in the cloud. Software projects are build, tested, and deployed using the Travis CI infrastructure without interrupting the development process. This report describes how Travis CI works, presents how time-driven, periodic building is implemented as well as how CI data visualization can be done, and proposes a way of dealing with dependency problems.

For any software developer who has spent days in “integration hell,” cobbling together myriad software components, Continuous Integration: Improving Software Quality and Reducing Risk illustrates how to transform integration from a necessary evil into an everyday part of the development process. The key, as the authors show, is to integrate regularly and often using continuous integration (CI) practices and techniques. The authors first examine the concept of CI and its practices from the ground up and then move on to explore other effective processes performed by CI systems, such as database integration, testing, inspection, deployment, and feedback. Through more than forty CI-related practices using application examples in different languages, readers learn that CI leads to more rapid software development, produces deployable software at every step in the development lifecycle, and reduces the time between defect introduction and detection, saving time and lowering costs. With successful implementation of CI, developers reduce risks and repetitive manual processes, and teams receive better project visibility. The book covers How to make integration a “non-event” on your software development projects How to reduce the amount of repetitive processes you perform when building your software Practices and techniques for using CI effectively with your teams Reducing the risks of late defect discovery, low-quality software, lack of visibility, and lack of deployable software Assessments of different CI servers and related tools on the market The book’s companion Web site, www.integratebutton.com, provides updates and code examples.

"Modern software is developed at a rapid pace. To sustain that rapid pace, organizations rely heavily on automated build, test, and release steps. To that end, Continuous Integration and Continuous Deployment (CI/CD) services take the incremental codebase changes that are produced by developers, compile, link, and package them into software deliverables, verify their functionality, and deliver them to end users. While CI/CD processes provide mission-critical features, if they are misconfigured or poorly operated, the pace of development may be slowed or even halted. To prevent such issues, in this thesis, we set out to study and improve the robustness and efficiency of CI/CD processes. First, we present two empirical studies that focus on robust configuration of CI/CD processes. To understand the ways in which CI/CD features are being used, we analyze a curated sample of 9,312 open source projects that are hosted on GitHub and have adopted the popular Travis CI service. We find that explicit deployment code is rare. Then, to analyze feature misuse, we propose Hansel--an anti-pattern detection tool for Travis CI specifications. We define four anti-patterns and Hansel detects anti-patterns in the Travis CI specifications of 894 projects (10%) in the corpus. Furthermore, we propose Gretel--an anti-pattern removal tool for Travis CI specifications, which can remove 70% of the most frequently occurring anti-pattern automatically. Our third empirical study focuses on robust CI/CD outcome data. In this work, we use openly available project metadata and CI/CD results of 1,276 GitHub projects that use Travis CI, to better understand the extent to which noise and heterogeneity are present in CI/CD outcome data. We find that: (1) 12% of passing builds have an actively ignored failure; (2) 9% of builds have a misleading or incorrect outcome on average; and (3) at least in 44% of thebroken builds, the breakage is local to a subset of build variants. Our fourth empirical study focuses on improving the efficiency of CI/CD services. We propose a programming language-agnostic approach to infer data from which build acceleration decisions can be made without relying upon build specifications. After inferring this data, our approach accelerates CI builds by caching the build environment and skipping unaffected build steps. To evaluate our approach, we mine 14,364 historical CI build records spanning three proprietary and seven open-source software projects. We find that accelerated builds achieve a substantial speed-up (two-fold in 74% of accelerated builds) with minimal resource overhead (i.e.,

Connect if you have questions at http://continuity.world/connect. Processes, amongst other things, can exponentially improve organizational culture. This book lays the foundation of building resilient processes for transformational leaders who aspire to drive culture change in their organizations. The principles of DevSecOps, Continuous Integration and Continuous Delivery form the recipe for success, and Continuous Improvement is at the heart of it. As you plow through the chapters of this book, you will virtually experience the thrills and the shivers of leading a crucial transformational change. And you will be able to define the next chapter of your very own journey. This is how I have structured the book: Chapter 1: Introduction Eases my readers into understanding and appreciating a Continuous Delivery Pipeline, extends the concepts to Continuous Everything and Everyone, and gives a brief introduction about myself. Chapter 2: Continuous Delivery As A Domain Domain-driven design (DDD) is known to be overkill for simple problems. After careful consideration of the issues that plague product releases (software, firmware, embedded systems, Internet of Things, * as a service, and the like), I decided to model the Continuous Delivery Pipeline as a domain. Chapter 3: Pipeline Domain Model Integrity In an academic setting of model-driven-development, we try to maintain a consistent and unified model throughout the teams. In reality, there could be many teams who work on different parts of the Continuous Delivery Pipeline ecosystem and the model tends to fragment. However, aspects of the model that are important should stay unified and other parts could be offered for customization. Chapter 4: Continuous Analytics And Insights Teams are required to zoom in and solve hard problems every day. While it is paramount to be able to get down on our knees and dig in, it is just as important to be able to zoom out and fathom the big picture. We need to see the forest through the trees. We should emphasize on learning patterns and trends over a period of time that offer direct insights into our business. These help us make tough calls that pay rich dividends in the long run. Chapter 5: A DevSecOps Seed Backlog A single prioritized Product Backlog is a key driver of an organization''s growth and sustainability. This chapter enables Product Owners to address epics related to not just Development but also Builds, Tests, Configuration, Deployment, Monitoring, KPIs, Operations, Network, Security and related issues that help teams experiment safely and turn great ideas into products. More importantly, this helps teams recover fast from not-so-great ideas. Chapter 6: The Twelve-Factor Pipeline Inspired by The Twelve-Factor App, the Twelve-Factor Pipeline establishes the same gold standards for the Pipeline application, as are applied to the products that flow through the Pipeline. Chapter 7: Segregation/Separation Of Duties Segregation of duties or separation of powers is a controversial topic in organizations that have dwelled on a legacy hierarchy long enough to confuse separation of duties with separation of departments. This chapter establishes guidelines on how we should implement Continuous Delivery Pipelines that improve speed, quality, and predictability without risking business. Chapter 8: Myth Busters Some organizations fall prey to age-old beliefs that have inherent flaws. This results in modernized approaches getting the boot and new gen tech leads stumbling over bureaucracy and red tape. This chapter pulls up the most damaging myths and addresses the elephant(s) in the room. Chapter 9: Resources Lists a set of resources.

Winner of the 2011 Jolt Excellence Award! Getting software released to users is often a painful, risky, and time-consuming process. This groundbreaking new book sets out the principles and technical practices that enable rapid, incremental delivery of high quality, valuable new functionality to users. Through automation of the build, deployment, and testing process, and improved collaboration between developers, testers, and operations, delivery teams can get changes released in a matter of hours— sometimes even minutes–no matter what the size of a project or the complexity of its code base. Jez Humble and David Farley begin by presenting the foundations of a rapid, reliable, low-risk delivery process. Next, they introduce the “deployment pipeline,” an automated process for managing all changes, from check-in to release. Finally, they discuss the “ecosystem” needed to support continuous delivery, from infrastructure, data and configuration management to governance. The authors introduce state-of-the-art techniques, including automated infrastructure management and data migration, and the use of virtualization. For each, they review key issues, identify best practices, and demonstrate how to mitigate risks. Coverage includes • Automating all facets of building, integrating, testing, and deploying software • Implementing deployment pipelines at team and organizational levels • Improving collaboration between developers, testers, and operations • Developing features incrementally on large and distributed teams • Implementing an effective configuration management strategy • Automating acceptance testing, from analysis to implementation • Testing capacity and other non-functional requirements • Implementing continuous deployment and zero-downtime releases • Managing infrastructure, data, components and dependencies • Navigating risk management, compliance, and auditing Whether you’re a developer, systems administrator, tester, or manager, this book will help your organization move from idea to release faster than ever—so you can deliver value to your business rapidly and reliably.
