Quickstart for continuous integration
This document provides an introduction to continuous integration (CI), including its objectives, benefits, and how to get started with CI. CI aims to integrate components, software, and infrastructure through short, frequent integration cycles to reduce integration problems and improve productivity. Benefits include anticipating risks early, reducing errors, providing fast feedback, lowering release stress, and enabling collaboration. The document recommends choosing build and scripting tools, using a configuration management system, selecting a CI tool like Jenkins, and setting up a CI "playground" for testing. It provides examples of configuring projects and jobs in Jenkins along with collecting build statistics, reports, and notifications.
Continuous integration practices to improve the software quality
This document discusses practices for continuous integration to improve software quality. It recommends analyzing workflows to find areas for automation. It also advocates for self-service builds and push-button deployments across environments. The document outlines patterns like committing code daily, enforcing code quality rules, and stopping broken builds quickly. It notes how continuous integration supports agile methods through daily feedback, using reports to continuously improve processes and quality over iterations.
Automated testing
Automated testing involves using special software to control test execution and compare actual and expected outcomes without human intervention. It allows tests to run automatically, increasing speed and coverage while reducing costs compared to manual testing. High risk, repetitive, tedious, and time-consuming tests are best candidates for automation. Proper planning, tool selection, scope definition, and maintenance are required for effective automated testing in agile environments. Automation should start small and be added incrementally with each new implementation.

Testing
Unit testing is a software development method that involves writing small pieces of code called units to test individual functions or components. This helps ensure code works as intended and finds bugs early. Key benefits of unit testing include keeping code simple, making code more maintainable and robust, and providing regression tests. However, developers sometimes avoid unit testing due to perceptions that it is tedious or not valuable. Tools like NUnit and Visual Studio support automating unit tests. Test-driven development is a technique where tests are written before code to specify desired behavior.

Continuous integration (CI) allows you to check the quality of your project on every developer commit. It's a key part of any Agile environment.
We will start with a 5 year old ASP.NET WebPages application and put it under CI with unit testing and other key metrics. The web project, has no modern best practices at all. This talk will demonstrate, step-by-step and line-by-line, adding a project to a continuous integration (CI) server.
The end result will be a project with the following:
- Automatic build on check-in
- Automatic reporting of unit tests
- Code duplication reporting
- Warning analysis
- REM: Automatic database upgrade
This will be great if you work with legacy code and feel the CI hurdle is big.

Introduction to continuous delivery
Continuous Delivery is a software development practice where code changes are automatically tested, built, and prepared for a release. The key principles are:
1) Make small, incremental code changes continuously that are always ready for production.
2) Automate testing, building, and deploying to reduce risk and make releases boring.
3) Use feature toggles to deploy incomplete features and control their rollout.
This allows software to be updated and released frequently in a sustainable way by catching issues early and improving quality. It is a cultural change that requires investment but provides benefits like faster feedback and the ability to respond quickly to demands.

Roofline Model for FPGA: A tool for Performance Analysis and Application Opti...NECST Lab @ Politecnico di Milano
The document proposes adapting the Roofline Model performance analysis tool for FPGAs. It aims to allow application designers to evaluate performance before acceleration, compare performance across platforms, and enable automatic HLS optimization. The adaptation is non-trivial as the compute bound performance limit on FPGAs depends on both the algorithm and hardware resources. An optimization flow and set of tools are under development to implement the Roofline Model approach for FPGAs.Continuous delivery - takeaways
The document discusses continuous delivery and identifies several common antipatterns and issues:
1) Deploying software manually without automation leads to unpredictable releases and difficulties.
2) Deploying only after development is complete misses opportunities for early testing in production-like environments.
3) Manual configuration management of production environments results in failures and differences between environments.
The document proposes automating processes, keeping everything in version control, and adopting a deployment pipeline to improve feedback and enable frequent, reliable releases. Blue-green deployments and canary releasing are also introduced to reduce risk when deploying new versions. Finally, common issues like infrequent deployments, poor application quality, poorly managed continuous integration, and poor configuration management are
The good the bad and the ugly - final
The document discusses integration and verification in technical automation. It defines integration as the process of combining components into larger assemblies and notes that integration asks for a dedicated approach and is a creative activity that enables verification. Verification itself is performed by testers to check features and find defects. The document emphasizes that integration and verification need to work together in a sound process to deliver high quality, fully verified systems to customers.

Continuous delivery is everywhere. Really?! Many teams still struggle to deliver well-tested product increments on a regular basis. Usually with the same old excuse: the (non)-functional tests are too complex and too expensive to implement thoroughly. But exactly the opposite is the case! In this talk, we briefly review the importance of early and regular testing of cloud-native applications and explain why monolithic CI pipelines are a dead end. We then show how easy it is to run integration, performance, security and acceptance tests continuously using Testkube directly on your Kubernetes cluster, fully integrated with a GitOps approach.

Journey to the center of DevOps - v6
1) The document discusses DevOps practices presented at India Agile Week 2013. It describes challenges of manual development and operations processes, including delays, failures, and finger pointing between teams.
2) DevOps aims to streamline the software development lifecycle by involving operations throughout the process. This is achieved by establishing a collaborative culture, adding operations stories to the product backlog, and having operations participate in sprints.
3) Automating tools and workflows provides visibility across the entire release and deployment pipeline. This allows for traceability, continuous integration and deployment, and standardized environments and processes.
Software Development Life Cycle
The document discusses several software development life cycle (SDLC) models:
- The waterfall model is a linear model consisting of requirements, design, implementation, testing, installation, and maintenance phases. It works well for stable requirements but lacks flexibility.
- The spiral model adds risk analysis and prototyping to the waterfall model. Each cycle consists of planning, risk evaluation, development, and planning for the next phase. It allows for early risk assessment and feedback.
- The incremental model prioritizes requirements and implements them in groups, delivering an operational product in each release. It lowers costs but requires good planning.
- The rapid application development (RAD) model emphasizes user involvement and productivity tools. It delivers functionality

Agile performance testing
This document discusses performance testing challenges for an agile development team working on a performance critical Java application. It estimates that manually executing performance tests against 9 configurations would take 1+ man-months. To address this, it evaluates options like adding more performance engineers, limiting tests and configurations, or automating performance testing. It recommends automating testing for benefits like running tests continuously and allowing small teams to efficiently test performance. The case study details how the team automated testing using JMeter, built a process integrated with TeamCity, and upgraded infrastructure to support concurrent testing. Automation reduced the testing cycle from over 1 man-month to 4 days, allowing more time for analysis and new testing while finding 17 issues.
AgileTesting_Ver1.0
The document discusses agile testing approaches. It defines testing as executing software with test cases to find failures and demonstrate correct execution. It then discusses key aspects of agile testing including: running tests iteratively throughout development rather than just at the end; automating tests wherever practical; and having testers work collaboratively as part of development teams. It outlines success factors like focusing on delivering customer value and continually improving testing practices. The document advocates for automating a large portion of testing to provide rapid feedback and free up resources while balancing automation costs.
An Automation Culture: The Key to Agile Success

Continuous Delivery ist allgegenwärtig. Wirklich?
Viele Teams straucheln immer noch dabei, regelmäßig gut getestete Produktinkremente zu liefern. Normalerweise mit der gleichen alten Ausrede: die (nicht)-funktionalen Tests seien zu aufwändig und zu teuer umzusetzen. Doch genau das Gegenteil ist der Fall!
In diesem Vortrag gehen wir kurz auf die Bedeutung früher und regelmäßiger (nicht)-funktionale Tests von Cloud-nativen Anwendungen ein und erläutern, warum monolithische CI-Pipelines eine Sackgasse sind.
Anschließend zeigen wir, wie einfach es ist, kontinuierliche Integrations-, Performance-, Security- und Akzeptanz-Tests mithilfe von Testkube zu integrieren und direkt im Cluster auszuführen.
Quality attributes in software architecture
This document discusses various quality attributes in software architecture including responsiveness, scalability, usability, security, accessibility, serviceability, extensibility, distributability, maintainability, portability, reliability, testability, and compatibility. For each attribute, it provides definitions and considerations for how to achieve that attribute in architecture and design. It also discusses relationships between attributes and references quality models for evaluating software.

AgileValues
In 2001, a group of software experts created the Agile Manifesto which established four values for agile software development:
Individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan. These values emphasize that while processes, documentation, contracts, and plans have value, interactions between people, working software, customer involvement, and adaptation to change are more important for successful software development.
AgileUserStory
A user story is a tool used in Agile software development to capture a description of a software feature from an end-user perspective. It describes the type of user, what they want and why. A user story helps create a simplified requirement description. It should have a short but unique title, follow an As a <user> I want <goal> so that <reason> format, include acceptance criteria in Given/When/Then format, and be sized in story points to fit into one iteration. The goal is to describe a feature from the customer's perspective without losing information.
AgileTerms
The document defines key terms used in Agile software development including roles like the Scrum Master and Product Owner, ceremonies like Sprint Planning and Retrospectives, processes like Sprints and Velocity, and work items like User Stories, Tasks, and Bugs. The goal is to familiarize people with common Agile terminology without fully explaining Agile itself.
AgileRoles
The document discusses key roles in Agile development including the Product Owner, Scrum Master, and Team Members. The Product Owner builds and manages the product backlog and ensures everyone understands the work. The Scrum Master coaches the team and resolves impediments. Team Members are ideally 5-7 cross-trained individuals who forecast work and help each other ensure success. Other important roles that interact with but are not part of the core team are also mentioned.
AgileProject
This document discusses how agile principles can be applied to projects. It explains that while agile does not specifically address projects, the two are not exclusive. A key intersection is translating a project's scope, timeline, and budget into agile work items and backlogs. This allows creating a roadmap to predict feature delivery order based on backlog size and historical team velocity or cycle time. The document also discusses accounting for other work and external dependencies in velocity and roadmaps to improve project planning and coordination.
AgileIteration
Iteration refers to the repetitive process of developing software in cycles. Short iterations allow for stakeholder feedback throughout development to address changes early. Faster iterations provide metrics for process improvement and reduce costs by delivering value to customers sooner, lowering overall project expenses. Iterative development with early and frequent feedback helps ensure the software being built satisfies customer needs.
AgileCeremonies
This document discusses several Agile ceremonies including backlog refining, sprint planning, stand ups, demos, and retrospectives. Backlog refining involves improving backlog item descriptions, estimating sizes, and allowing questions. Sprint planning involves selecting backlog items for the sprint and estimating tasks. Stand ups involve each member discussing what they did, will do, and any roadblocks. Demos are informal showings of accomplishments. Retrospectives allow only team members to discuss what went well, poorly, and could be improved going forward. These ceremonies aim to create common understanding, commitment, continuous improvement, and informed stakeholders.
AgileBVIR
A Big Visible Information Radiator (BVIR) is a visual tool used in Agile teams to communicate information to the whole team. It can display things like a burn down chart to show iteration status and progress toward goals. A burn up chart shows progress while accounting for scope changes. A Kanban board visually depicts the flow of work items through different stages like ready, in process, and done. Other useful information for a BVIR includes team values, retrospective goals, definitions of ready and done, and a contact list.
