Test-Driven-Development for Networking: Making CI Work for You by Colin McNam...DevOps4Networks
The document discusses how continuous integration (CI) and test-driven development (TDD) can benefit network engineers. It presents an overview of CI/TDD processes and concepts. A key point is that CI/TDD can increase quality, decrease risk, and increase development speed for network operations. The document proposes a maturity model to guide organizations in implementing CI/TDD practices for networking, starting from basic self-service builds and progressing to integrated testing and continuous deployment.
GitLab is a popular DevOps platform that provides an ecosystem for code management, release management, and continuous integration and delivery (CI/CD) pipelines. This document discusses implementing DevOps using the GitLab ecosystem, including its tools, branching strategies, and designing a GitLab-based DevOps implementation. It provides an overview of the key GitLab tools and interfaces for users, and describes best practices for areas like source code management, continuous integration, monitoring, and security.
The document discusses the use of Gerrit for code review in agile workflows. It begins by explaining some of the challenges of continuous integration, including broken builds that can occur when developers push untested code. It then discusses how Git addresses this issue by enabling early code integration through topic branches. However, it notes that Git alone does not enforce policy. Gerrit is introduced as a tool that builds upon Git to enable code review and enforce access controls and policies. It provides an overview of key Gerrit features like automatic topic branches, trigger builds, and democratic voting processes.

DCI presentation during OpenStack Montréal - 2018-06Gonéri Le Bouder
This document discusses distributed continuous integration (DCI), which aims to change how partners interact with Red Hat OpenStack. DCI allows partners and customers to test the latest Red Hat OpenStack builds in their own environments. It shortens certification testing time and simplifies upgrades by testing incremental changes. DCI provides automated feedback to Red Hat to improve products based on partner and customer use cases.
The document discusses key topics from a session on build and release engineering, including continuous integration, continuous delivery, and continuous deployment. It defines these terms and lists the main steps and principles associated with each. Specific topics covered include software release principles, configuring management, deployment pipelines, testing approaches, and managing environments and releases of complex systems. The target audience for these concepts is listed as various engineering and operations roles.
An agile software development process is proposed that allows for a fixed budget and scope. The process involves planning with user stories, allocating stories to sprints, daily scrums, automated testing and deployment, and client sign-off. Any additional requirements are tracked as change requests that can be completed with contingencies or additional funds. The environments are separated to allow efficient testing and deployment without overhead. This process aims to balance the agile development benefits with the fixed budget needs of CFOs.

The document outlines git branching strategies and principles of continuous integration. It states that the integration branch is where developers continuously integrate code, with the integration branch being master. All integrations onto the integration branch must pass automated tests, and only trivial merges are allowed. Successful integrations onto master will trigger automated pipelines. Development branches may target maintenance branches for fixes rather than the integration branch, and integrations onto promotion branches are also automated.
This document discusses Continuous DevOps using goPaddle. goPaddle is a microservices-based DevOps platform that enables continuous build, deployment, and delivery of applications. It allows users to define service architectures, create GitHub components, build Docker container blueprints, and deploy applications on Kubernetes clusters across public/private clouds or on-premise. goPaddle supports continuous DevOps practices like CI/CD pipelines and provides benefits such as reduced TCO, faster deployments, auto-scaling, and application monitoring.
This presentation compares testing in the Waterfall vs Agile processes. In Waterfall, testing occurs after development is complete, while in Agile testing occurs simultaneously with development each sprint. Requirements are fixed in Waterfall but change frequently in Agile. Test planning is done once in Waterfall but reviewed each sprint in Agile. The test team is separate from developers in Waterfall but integrated in Agile. Documentation is more extensive in Waterfall while only as needed in Agile. Regression testing includes all test cases in Waterfall but only needed ones each sprint in Agile.
The document discusses tools for software development including Git, Gerrit, Jenkins, and TeamForge. It provides an overview of each tool's purpose and how they can integrate together. Key points include that Gerrit allows for code review and Git hosting, Jenkins enables continuous integration, and TeamForge provides an enterprise platform that integrates these tools with additional features for access management, compliance, and application lifecycle management.
UXDX Dublin - No risk, no reward. The joys of testing in production, by Fabio...UXDXConf
As the Director of Mobile Engineering & Principle Engineer, Natalia Bartol & Fabio Cognigni have dealt with a number of product launches for Hudson Bay Company.
They took the opportunity at UXDX Dublin to speak about everything involved in testing and deploying new features and products.
The document discusses connecting agile development upstream and downstream using open source tools. It describes how CollabNet's TeamForge platform can be used to integrate tools and processes, provide traceability across the development lifecycle, and offer metrics and reporting. Demos are provided of the platform and accelerator packs, which extend TeamForge with predefined solutions for agile development and delivery.
Version control systems like Git are essential tools in software development that allow tracking of code changes and collaboration between programmers. Git repositories provided by GitHub and GitLab are two of the most popular options. While GitHub is mainly used for code sharing and includes social features, GitLab provides additional DevOps capabilities like integrated continuous integration and deployment. Both tools have similar features for code review, issue tracking, and documentation, but GitLab offers more robust project management and security features for enterprises. Version control systems streamline development and allow easy reverting of mistakes or changes, improving productivity and reducing errors in software projects.
The Definitive Guide to Implementing Shift Left Testing in QARapidValue
In today's digital world, even though most of the projects are following the Agile methodology, often testers might not get enough time to quantify the problem scope and test the product effectively. Even if a sprint lasts for two weeks, the QA team would get the complete functionality for testing, only two or three days before the sprint completion. Eventually, the QA team would have to rush the testing, struggle for test completion and even end up with improper test coverage and bugs being leaked into production. So the testing phase is often considered as a bottleneck for the release by the management.
Studies done by analysts suggest that the maximum number of defects occur during the requirement
and design phase of the software development life cycle. More than half of the defects occur during the
requirement and design phase of the SDLC, i.e 56% of the total defects. Out of this 56%, 23% occurs during the design phase, 7% in the development phase and 10% defects emerge during the other phases. 2019 witnessed test automation going mainstream with 44% of IT organizations automating more than 50% of
all testing and these figures are expected to go up in the upcoming years. Thus it becomes highly necessary to step up the testing game and ensure that it is done quite efficiently and this is where Shift Left Testing comes into play. Detecting defects early in the software development cycle can prove to be very crucial in regards to cost and efficiency.
This whitepaper discusses how shift left testing could help you reimagine the entire QA testing process.
Tomas Riha presented on the principles and benefits of continuous delivery. Continuous delivery aims to have applications always ready for release through a highly automated process of continuous integration, testing, and deployment. It emphasizes automating all parts of the release process, building quality in from the start, and having all team members share responsibility for releases. Frequent releases allow for faster feedback and reduce risks from large code changes. Continuous delivery helps enable test-driven development and improves the ability to verify features continuously.
Webinar "Differences between Testing in Waterfall and Agile"
presentation by Maria Teryokhina
http://www.exigenservices.ru/webinars/testing-in-waterfall-and-agile
This document discusses strategies for continuously delivering distributed systems while managing risks. It recommends:
1. Hardening application artifacts through extensive testing at each stage, from unit to integration to production.
2. Releasing changes incrementally using techniques like canary releasing to catch issues early.
3. Monitoring systems closely and having the ability to rollback changes if needed to lower the risk of failures affecting users.
The goal is to deploy changes frequently while minimizing risk through automation, independent evolvability of services, and the ability to fail safely.
Pivotal Labs Open View Presentation Quality Assurance And Developer Testingguestc8adce
1) The document discusses moving from a traditional development model where QA finds bugs after development is complete, to a model where quality is the focal point and everyone is responsible for testing.
2) It advocates for automating tests and running them frequently during development to find bugs early and have confidence in changes.
3) The goal is to develop software quickly with low defect rates by shifting left the work of finding bugs through techniques like test-driven development.
The document provides an interim project report for developing an Update Center for NetApp's Snap Creator framework. The report outlines the problem of needing a system to monitor compatibility between versions of Snap Creator servers, agents, and plugins. It describes the team's progress in building the Update Center using Ruby on Rails with a database to track versions and compatibility. The team's goals are to finalize the Update Center and integrate it with NetApp's build server so it can be accessed on their network.

Distributed Proxies have opened the floodgates for Service Meshes to provide substantial value at the Application Networking Layer, but early adopters of Service Meshes are often overwhelmed by operational complexities. How do you ensure that the proxy is distributed everywhere your software runs? How do you safely upgrade or roll back all those proxies? How can you ensure that your network config is correct - without pushing it to production and risking an outage? Following the GitOps Principles is key to simplifying Service Mesh Operations. Defining the entire service mesh declaratively - be it installation, proxy injection, or configuration - provides a mechanism to safely manage the complexities of a service mesh. Continuously reconciling declarative config with the latest service mesh release keeps you from being caught off-guard by CVEs. Progressive Delivery tools enable seamless movement from one version of a service mesh to another - and back - with minimal impact to traffic.
The document provides an introduction to DevOps. It explains that DevOps aims to integrate developers and operations teams to improve collaboration and productivity by automating infrastructure, workflows, and measuring application performance. This addresses issues where development teams faced delays deploying code and operations teams struggled with managing an increasing number of servers. DevOps adopts practices like automating infrastructure configuration and code deployment to enable continuous delivery and fast, reliable releases while allowing development and production environments to be identical.

GitOps is a way of implementing continuous deployment for cloud native applications using Kubernetes. It focuses on a developer-centric experience by using tools like Git and continuous deployment that developers are already familiar with. GitOps uses Git as the single source of truth for infrastructure configuration and changes. It has four main principles: the system is described declaratively, Git is the single source of truth, changes can be automatically applied, and the system is continuously validated and improved. Common GitOps operators that facilitate continuous delivery include Flux, Argo CD, and Jenkins X. The GitOps model uses a pull-based deployment approach rather than pushing changes, improving security, observability, and productivity.
GitOps è un nuovo metodo di CD che utilizza Git come unica fonte di verità per le applicazioni e per l'infrastruttura (declarative infrastructure/infrastructure as code), fornendo sia il controllo delle revisioni che il controllo delle modifiche. In questo talk vedremo come implementare workflow di CI/CD Gitops basati su Kubernetes, dalla teoria alla pratica passando in rassegna i principali strumenti oggi a disposizione come ArgoCD, Flux (aka Gitops engine) e JenkinsX
Over time, the software industry has come up with many ways to deliver code. Why is it so important to be in production as much as possible? What advantages and disadvantages do we have in rapid releases? Let’s talk about how to be faster, safer, and with better quality.

Full stack development best practice and toolsetReid Lai
The document discusses full stack development best practices and toolsets. It defines a full stack developer as someone proficient in both front-end and back-end development. It also discusses how full stack developers fit into scrum teams, the relationship between agile development and DevOps practices like continuous integration, delivery and deployment. Finally, it covers using containers and Docker for DevOps and orchestrating required application services.

Understanding the GitOps Workflow and CICD Pipeline - What It Is, Why It Matt...Gibran Badrulzaman
Travelio Tech Talks 2022 presentation
The recommended workflow for implementing GitOps with Kubernetes manifests is known as trunk-based development. This method defines one branch as the "trunk" and carries out development on each environment in a different short-lived branch. When development is complete for that environment, the developer creates a pull request for the branch to the trunk. Developers can also create a fork to work on an environment, and then create a branch to merge the fork into the trunk.
Once the proper approvals are done, the pull request (or the branch from the fork) gets merged into the trunk. The branch for that feature is deleted, keeping your branches to a minimum. Trunk-based development trades branches for directories.
You can think of the trunk as a "main" or primary branch. production and prod are popular names for the trunk branch.
Trunk-based development came about to enable continuous integration and continuous delivery by supplying a development model focused on the fast delivery of changes to applications. But this model also works for GitOps repositories because it keeps things simple and more in tune with how Kustomize and Helm work. When you record deltas between environments, you can clearly see what changes will be merged into the trunk. You won’t have to cherry-pick nearly as often, and you’ll have the confidence that what is in your Git repository is what is actually going into your environment. This is what you want in a GitOps workflow.
DevOps CI Automation Continuous IntegrationIRJET Journal
This document discusses implementing a DevOps continuous integration (CI) automation pipeline for test automation. It involves developing a Java-based test automation framework using Selenium and TestNG. Test cases and framework code are stored in a GitHub repository. Jenkins is configured to automatically build and run tests whenever code is committed to GitHub. This allows for continuous regression testing and helps deliver defect-free software by catching issues early in the development cycle.
These are the slides for a talk/workshop delivered to the Cloud Native Wales user group (@CloudNativeWal) on 2019-01-10.
In these slides, we go over some principles of gitops and a hands on session to apply these to manage a microservice.

Modern software project have external dependencies
This dependencies are organized in packages
Packages can be provided by external developers and platforms e.g. GitHub or https://packagist.org/
Usually the dependencies are up to date during development of a software
After go live dependencies are updated unregular on e.g. feature requests

Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

GIT WORKFLOW, FROM DEVELOPMENT TO DEPLOYMENT
REDEFINED!
PRAVAT KUMAR SUTAR
Senior Solution Integrator, Ericsson India Global Services Pvt. Ltd.
ABSTRACT
Distributed version control or Decentralized version control, allows many software developers to
work on a given project without requiring them to share a common network. The software revisions
are stored in a distributed revision control system (DRCS), also known as a distributed version control
system (DVCS).
One such open source DVCS, Git, provides a lightweight yet robust framework for tracking and
controlling changes to a project's files, in particular to source code, documentation, and web pages.
For individual researchers, Git provides a powerful way to track and compare versions, retrace errors,
explore new approaches in a structured manner, while maintaining a full audit trail. For larger
collaborative efforts, Git and Git hosting services make it possible for everyone to work
asynchronously and merge their contributions at any time, all the while maintaining a complete
authorship trail.
In this paper, I provide an overview of Git work flow that can be followed across organizations and I
have highlighted both development and deployment including the code review through GERRIT and
the deployment through Jenkins/Hudson and how it can leverage development/deployment process of
Agile Methodology more reproducible and transparent, foster new collaborations, and support novel
uses.
Keywords: Distributed Version Control Systems (DVCs), Agile Methodology, GIT, GERRIT,
Hudson/Jenkins, repository, SPRINT, Clone, Checkout, Switch, Rebase, Branch, Tag, Development
Server, Acceptance Server, User Acceptance Server and Production Server, Apache Tomcat.
PURPOSE
CollabNetTeamforge’sGit integration is powered by Gerrit, an open source Git server which enforces
access control on Git repositories and supports powerful review features and integration points for
continuous integration tools like Jenkins. Few points are necessary to make out here
a. Source code is maintained in Teamforge’s remote repository
b. The code changes are not pushed directly to remote repository instead it is pushed to Gerrit
for review.
c. Jenkins is used for continuous integration, gerrit-trigger for reviewing the code in Gerritforge,
for building the maven projects and deploying the projects web archive in the application
servers.
d. The User Stories, Epics, Defects and Tasks are maintained in Teamforge’s Tracker artifacts.
The basic purposesare
a. How efficiently we can manage the development and deployment cycle with this GIT version
control system.

DESCRIPTION
Step 1: ASPRINT-<N>Branch (Ex. SPRINT-1) will be created at the starting of each sprint in remote
eforge GIT repository.
Step 2: The developer will clone the remote repository to the local system for first time. From the 2nd
time onwards, the developer has to fetch from remote and checkout or switch to SPRINT-<N>
branch.
Step 3: The developer will create a separate feature branch in the local based on the ticket, s/he has
accepted or assigned to him/her. The name of the branch will be sprint-ticket-<ticket-no>. Here
sprint number is not mentioned in the feature branch because a ticket may not be completed in a
single sprint.
Below are the steps
Fetch SPRINT-<N> from remote Rebase remote SPRINT-<N> branch with local SPRINT-
<N>Create new feature branch from SPRINT-<N>
Example:
If a developer works in defects/task i.e. “artf1234” of SPRINT-1, then below steps need to be
followed:
1. git fetch origin
2. git checkout SPRINT-1
3. git rebase origin/SPRINT-1 SPRINT-1
4. git checkout -b sprint-ticket-artf1234
Step 4: Once the code changes are done, the developer will do unit testing to validate everything
looks fine based on the requirement in the ticket. At this stage, the developer will test the code in local
system. The developer will commit the changes to the feature branch and push it for review to
GERRIT SPRINT-<N> branch.
Note: Kindly note that the modified code won’t go to the GIT remote repository directly rather it will
go to GERRIT for code review.
Step 5: The reviewer(s) will review the code changes in GERRIT and can provide the
suggestions/recommendations, abandon or merge the changes. In case it is abandoned, the watch list
will get notification on this and the developer who worked on the ticket need to rework based on the
suggestions and recommendations and this process will be continued. In case the reviewer is
approving the changes, the code will be merged to SPRINT-<N> branch ofthe remote repository.
Step 6: If the merge is successful, no action is required. The latest code will move to the remote
repository but if a conflict occurs even after the review is success, GERRIT will not be able to merge
and abandon the commit. A notification will be sent to the watch list. The developer need to fetch,
rebase (rebase feature branch with remote SPRINT-<N>) to resolve the conflicts and push the updated
code to GERRIT again. Again the reviewer, review the changes and merge the code to GIT remote
repository.
Step 7: The deployment process starts from here. Once the code changes are merged with the remote
repository, a tag for DEV release will be created with name DEV-SPRINT-<N>-<DATE>-<TIME>.

Step 8: The DEV-SPRINT-<N>-<DATE>-<TIME> tag will be deployed to DEV application server
by Jenkins.
Step 9: Testing will be performed in DEV.This deployment to DEV and ACC is a continuous process
that can be done partially or completely. If testing fails in DEV, the team will be notified and
corrective action will be taken in SPRINT-<N> branch.
Step 10: If testing is successful in DEV, the deployment can be done in ACC.
Step 11: Testing will be performed in ACC. If testing fails in ACC, the team will be notified and
corrective action will be taken in SPRINT-<N> branch.
Step 12: If testing is success in ACC, a tag for PROD deployment will be created from the SPRINT-
<N> branch as it will be the stable one. The syntax of the tag name for PROD will bePRD-SPRINT-
<N>-<DATE>-<TIME>.
Step 13: The deployment will be done in User Acceptance Testing (UAT) Server with PRD-
SPRINT-<N>-<DATE>-<TIME>tag.
Step 14: Testing will be performed in UAT. If testing is successful, deployment plan will be made for
Production release. If testing fails, the corrective action will be taken in SPRINT-<N> branch and
again the whole deployment process will be continued as is.
Step 15: Deployment will be done in Production once testing in UAT is successful.
Step 16: Testing will be performed in production. If testing fails at some point, the code will be
reverted back to the previous one and the SPRINT-<N> will be marked as fail.
Step 17: If testing is successful, the code will be merged in a master branch.
Note: Here master is the stable branch which will always be updated after a successful production
release.
CONCLUSION
Since GIT is a standard tool that is widely used and backed by a large developer community, there are
numerous resources for learning and seeking helpofficial tutorial athttp://git-scm.com. GIT can be
readily used without any knowledge of command-line tools due to the available of many fully
featured GIT graphic user interfaces http://git-scm.com/downloads/guiswebsite. However, leveraging
its full potential, especially when working on complex projects where one might encounter unwieldy
merge conflicts, comes at a significant learning cost. There are also comparable alternatives to GIT
(e.g. Mercurial) which offer fewer granularities but are more user-friendly but as a matter of fact, the
workflow is important on how you are defining the development, code review and deployment
process.More the workflow streamlined; more will be the productivity gain.
