Agile, Testing and DevOps: Are they a Separate conversation or a progression of capability?
DevOps, Testing and Agile have shared environments that facilitate working together. These three methods are more than simply adopting new tools and processes and the synergy involves building a development and a stable Continuous Integration (CI) infrastructure, as well as an automated pipeline that moves deliverables from development to production. They can work together and the entire build process should be transparent, and it should enable and support development and operations. This transformation depends on: significant changes in culture; roles and responsibilities; team structure; tools and processes.
The Round Table session is the last of the joint morning session with the other two co-located events. This session is for 45 minutes of which there will be around ten minutes for a general summing up at the end. The speaker at each table will have a set theme and delegates join any table that they are interested in. They are given all the topics with their joining instructions and again at the time of registration and so make their choice on the topics that they want to attend. This is a discussion group and so no presentation slides are necessary, but please submit a topic if you would like to chair a discussion on a topic related to Testing, Agile and DevOps.
Benefits of attending:
We are looking for speakers willing to share their experiences and stories about your work in the field of DevOps. If you wish to submit a proposal to present at this event please fill in the speaker’s response form.
Topics to be covered:
Dorothy Graham, Software Testing Consultant
There are many places to visit it the world and it can be interesting to see "where you've been". There are many places in the software for tests to visit, and seeing "where the tests have been" can be very interesting for testers.
Dot Graham explains what coverage is, and why it can be misleading to talk about 100% coverage. Coverage is a relationship between the tests and the software being tested, and is an objective measurement of some aspect of thoroughness of the testing.
There ways in which the term coverage is mis-used, and four caveats of coverage which you should be aware of.
So is coverage a good thing to have? In other words, should testing be thorough? Not necessarily; sometimes testing should be more like strawberry jam than butter or margarine. Whenever you hear the term "coverage", there two important questions that you should always ask: Coverage of what? and Why?
Maria Ball and Terry Bowen, Senior Project Managers, Media Services, BBC Design & Engineering Platform
When the stakeholder "just" wants something simple done, they tend to expect it to be done quickly. What happens when there is more than one team involved?
In a large organisation, teams often work in silos, use their own flavour of Agile, and have their own roadmaps. It can be challenging to get the alignment and the flexibility needed to deliver a simple request. This is then complicated when the requirements evolve from the initial request to something more. Maria Ball and Terry Bowen discuss the complications they faced in managing the development and delivery of a project that required three internal teams and an external supplier, while using Agile methodology. They will share how they were able to resolve the conflicts and software limitations they came across to deliver the feature.
Kevin Rutherford, Software development coach
This talk presents a simple visualisation tool that helps software teams self-organise, deliver, and communicate more effectively. The talk uses examples from recent software development projects in a variety of organisations, showing how this technique has improved both the rate of software delivery and the engagement of key stakeholders.
Mark Smalley, IT Management Consultant, Smalley
A fast-moving, entertaining and insightful session in which you’ll learn about:
♦ 'Selling' the value of DevOps to business executives
♦ Discovering the weakest link in the business-IT-business value chain
♦ Identifying effective collaborative behaviour between business and IT
♦ An ancient DevOps proverb “If you meet DevOps on the road, kill it”
Stephen Mounsey, Agile Coach
Are you really listening? Listening is an important skill for any human being but for a tester an essential skill. If part of testing is about information gathering and interpretation then Listening is a key component. A look at the art of listening, parallels drawn between listening theory and how we test.
Ash Winter, Consulting Tester and Speaker
API design looks easy, right? Lots of material, methods and examples to look at. However, we've not been on a team that hasn't struggled to build a clean interface for their consumers. From unconventional use of status codes, difficult to parse responses to endless debates about what to name endpoints. This is coupled with iteratively built API's, which potentially realise value and feedback earlier but may suffer from inconsistency over time.
By testing first with effective automation, common errors with API design can be flushed out quicker, even before the code has been written. Design and architecture should not be left to the developers and architects, by following some of these guidelines, as a Tester you will be able to contribute to a consistent, transparent and maintainable API.
Seb Rose, Cucumber
When you invest in the stock market you’ll often be warned to “remember that the value of investments can go down as well as up”. For over a decade User Stories have been the rock steady investment of agile adoption - and they’ve come a long way since XP called them “a placeholder for a conversation”. It’s time to re-evaluate what user stories are trying to achieve, what they’re good for, and why so many of them suck. In this session we’ll explore what a good user story should look like and discover why so many of them fail to live up to our expectations. We'll look under the covers of the INVEST acronym, popularised by Mike Kohn to help people write better user stories and look at why, in many cases, it doesn’t seem to have helped. It's time to stop investing in the boring, formulaic user stories that litter your boards, choke your JIRA and stifle your meetings. Today we're going to see how to make user stories RIVETing again.
Dorothy Graham, Software testing consultant, speaker and author
Testing has been around for a long time, but has changed a lot over the years. Agile and DevOps are “the new kids on the block” but are fast becoming mainstream. What are the roots of the changes and popularity of new approaches and how have they evolved over the years? What prophets were around years ago who foresaw current trends? In this presentation, Dorothy Graham leads you through some of her early experiences in testing and early encounters with precursors to Agile and DevOps. We look at why Agile has “taken off” and why DevOps is a hot topic today, and what the role of testing has been, is now and perhaps should be in the future.
- a personal history of testing
- the “grandfather” of agile and DevOps
- what problems do Agile and DevOps solve?
- what’s next?
Matthew Skelton, Co-founder and Principal Consultant, Skelton Thatcher Consulting Ltd
Moving from a monolith to microservices can be daunting. How do we choose the right bounded contexts? How small should services be? Which teams should get which services? And how do we keep things from falling apart?
By starting with the needs of the team, we can infer some useful heuristics for evolving from a monolithic architecture to a set of more loosely coupled services.
Giovanni Asproni, Lead Consultant, Zuhlke Engineering Limited
What does it take to get to a system where I can create a new service in just a few lines of code, and live with the result? In the transition to microservices, it’s critical to consider, and provide support for, the whole lifecycle of a service. Except that now it’s a fleet of services where there are just too many to manage by hand. In this talk, Giovanni will discuss some of the technical and organisational infrastructure that makes microservices work in practice.
Amany Elbanna, Senior Lecturer in Information Systems, Royal Holloway University of London
In this talk, I will explore what adopting agile has meant to the IS community and argue that our focus on the ‘doing’ of it has blinded us from the bigger picture. I will move beyond the practice to the being agile or agility and show that how this change in the mindset could change how we practice IT. For any organisation, the key is not what methodology IT adopts but what it means for the business. It is indeed time to think agility and how the IT function as a whole can tightly connect with each other and its decisions are tightly connected to customers. Agile practices could play a part but the challenge is to achieve IT agility for the benefit of customers. In this talk, I will give concrete examples, reflect on different organisations’ experience and present a successful case of agility.
Stephen Walters, Software Lead Solution Consultant, HPE
Why do transformations fail and how can we prevent it? What can DevOps & Agile teach us about our approach? Analysis from Gartner tells us that the biggest blockers are People (50%) and Process (37%), otherwise known as the culture, and changing culture is a difficult thing to do. There will always be resistance to a new path and finding the absolute correct path can be one littered with hazards and problems. To remove the risks and issues requires a new way of thinking about how we transform, but that requires a new culture, and so we get stuck in a cycle. This presentation will show how using a third party can be beneficial and how the relationship should be structured, along with a framework and engagement model for transformation.
Victor Laurel, Head of DevOps, Sogeti UK
Regardless of how DevOps begins in your organisation, the automation, continuous integration, and continuous delivery that it enables are the cornerstones of digital innovation, speed and cost effectiveness. Moving to a DevOps way of working is a complex journey, and one that offers huge rewards, but each journey is unique. Our presentation will illustrate the wide range of challenges that our customers have experienced, from collaborative to technical to philosophical; and showcase how they have addressed these factors to enable continuous deployment and deliver quantifiable business value.
This presentation will:
♦ Explain how you can kick start your organisation’s transformation
♦ Review how good process and new operating models can break down silos
♦ Address how testing fits into DevOps, and how test maturity is key to deliver best practice
Florent Cenedese, Senior Solution Consultant, TIBCO
A microservices architecture enables unprecedented agility and scalability, but also introduces its own set of complexities, and not all organizations have the right set of resources to put in to their microservices project to ensure their success. In this session we explore best practices for making this happen:
♦ What microservices are and where they should be used in the enterprise;
♦ How to leverage existing services without the need to rewrite them, then easily expose them as RESTful APIs;
♦ The choreography of microservices and how to keep it simple;
♦ Leveraging important technology enablers:
• The native tooling of your PaaS or container platform including monitoring, logging and management so you can focus on the business logic of your services;
• Microservices patterns such as configuration management, service registry & discovery and circuit breakers;
• DevOps tooling including Maven, Continuous Delivery Pipelines & Unit Testing;
♦ Why multi-cloud is a reality and you need to embrace it
Daniel Bryant, Chief Scientist at OpenCredo and CTO, SpectoLabs
All is not completely rosy in microservice-land. It is often a sign of an architectural approach’s maturity that in addition to the emergence of well established principles and practices, that anti-patterns also begin to be identified and classified. In this talk Daniel will introduce the 2016 edition of the seven deadly sins that if left unchecked could easily ruin your next microservices project... This talk will take a tour of some of the nastiest anti-patterns in microservices, giving you the tools to not only avoid but also slay these demons before they tie up your project in their own special brand of hell.
Topics covered include:
• Envy - introducing inappropriate intimacy within services by creating a shared domain model, and how many teams deploy and use data stores incorrectly;
• Wrath - failing to deal with the inevitable bad things that occur within a distributed system;
• Sloth - ignoring the importance of NFRs; and
• Lust - embracing the latest and greatest technology without evaluating the impact incurred by these choices.
Jussi Nummelin, Resident Wharfie, Kontena
Docker containers have brought great opportunities to shorten the deployment process through continuous integration and delivery of applications and microservices. This applies equally to enterprise datacenters as well as the cloud.
Jussi, an experienced software architect, will use this presentation to discuss solutions and benefits of a deeply-integrated deployment pipeline using technologies such as container management platforms, Docker containers, and the drone.io Cl tool. Jussi also will demonstrate deployment of a CI/CD pipeline using container management, as well as show how to deploy a containerized application through a continuous delivery pipeline.
James Heggs, CLOS Consultancy
A tutorial talk that will provide detail for creating your GKE cluster, utilising Kubernetes (k8s) and Docker to spin up a Jenkins container, using k8s to spin up Jenkins build agents, defining the build pipeline as code, creating a spring boot app as a docker container and finally deploying the application with k8s. Phew there is a lot to get through…so buckle in we’re in for the long haul. #buzzwordbingo
