Why people hate working in agile teams, and what you can do about it
by Ben Linders - Trainer / Coach / Adviser / Author / Speaker
from Tilburg, Netherlands
By now, many of us have been through one or more "agile transformations". We've been surrounded by agile coaches and Scrum masters who tried to help us adapt to agile, with managers who became servant leaders. Hopefully they weren't telling you what to do or how to do your work! A lot of people simply hate working in agile teams - Ben hears that all the time. And that is why he's here! In this talk, Ben will explore the difficulties of collaborating in teams and what we can do to make it beneficial and worthwhile for people to work in teams. Ben will delve into what teams really need, and what leaders should do and should not do to support them, including providing an environment and culture where teams can flourish and supporting teams in removing barriers. Through this talk, attendees will gain a better understanding of the reasons why people struggle to work in agile teams, and what leaders can do to create a positive and supportive environment for teams. The talk is intended for anyone working in a team or working with teams, from agile coaches and Scrum masters to managers and team members who are looking to improve their collaboration skills and create a more positive and productive work environment.

Automated Lighthouse reporting with WebdriverIO
by Hugh McCamphill - SDET Tech Lead @ ESW
from Belfast, Northern Ireland, United Kingdom
Hugh will demonstrate how to use Lighthouse, a tool available in Chrome, to provide insights into your web application's performance and accessibility. He will explain how the score given by Lighthouse can affect where your web application appears in the search engine results, which can be crucial for businesses trying to sell or promote their products. Hugh will show how to run an audit on any webpage, including pages behind authentication, and how to test performance as part of a user journey, reusing existing automated tests. He will focus on leveraging existing WebdriverIO-based tests, with minimal extra work, to generate Lighthouse reports that cover user journeys, page navigations, and page loads, in both mobile and desktop views. To set the scene, Hugh will discuss the importance of a focus on improving Lighthouse scores and give an overview of the type of information it provides. He will also cover some basic alternative ways to get the scores that Lighthouse provides if not using WebdriverIO. Attendees will leave the talk with a better understanding of the insights that Lighthouse can provide, how to include user journeys in Lighthouse audits as part of automated WebdriverIO tests, and how to incorporate the audits into their pipeline. In short, take advantage of Lighthouse's capabilities and improve your web application's performance, accessibility, and search engine visibility.

Everything as Code - test distribution with K8s and Testkube
by Tomasz Konieczny - Quality Consultant
from Gliwice, Poland
The talk focuses on the importance of quality pipelines that provide instant and complete feedback in modern products. Automated tests are essential for achieving this goal, but they can quickly make quality pipelines complex and difficult to maintain. Additionally, creating execution infrastructure from scratch can be time-consuming. Testkube is an open-source tool that simplifies the distribution of tests to Kubernetes clusters. It offers a unified approach to test orchestration and execution by abstracting away various testing frameworks and tools. By utilizing Kubernetes-native Custom Resource Definitions (CRDs), Testkube can leverage the scalability and reliability of Kubernetes for test-specific purposes. Additionally, Testkube CRDs enable the management of all testing resources in a GitOps manner. During the talk, attendees will learn how to set up Testkube and configure various test types, including Cypress, Postman, and K6, to build an efficient quality pipeline, and simplify test distribution and management while leveraging Kubernetes for reliability and scalability.
Tomasz is a highly experienced Test Architect and Quality Consultant with a true passion for all things related to software quality. He is a devoted advocate of DevOps, and is always on the lookout for ways to automate everything. At present, Tomasz is the QA Lead at Testkube, an innovative open-source project that streamlines the distribution of tests to Kubernetes clusters. He is also actively involved in the testing community, sharing his extensive knowledge and insights through a variety of mediums such as blog posts, articles, and conference talks. Over the last few years, he has delivered 50+ talks at international and nationwide conferences, covering a diverse range of topics related to software development and quality, including the evolution of quality approaches in software development, automated tests as quality pipeline data feed, and serverless architecture to speed up tests. He also talks about test environments management with Docker, insecurity by design, scaling blockchain with Lightning Network, and many others. Additionally, Tomasz is always eager to experiment with new ideas and concepts, believing that it is worth taking risks to achieve great results. His goal is to continue working on unique and challenging projects, while always enjoying his work as much as he does now.

Breaking the mold: A provocative discussion on moral values and their impact on society and QA industry
by Anton Angelov - CTO of Automate The Planet Ltd, Inventor of BELLATRIX Test Automation Framework, Author
from Sofia, Bulgaria
We will wrap up with Anton's talk focused on the essential role that moral values play in shaping individuals and society as a whole. Lawrence Kohlberg's theory of moral development identifies six stages, each with its own characteristics and values. In the QA industry, it is crucial to have a strong ethical framework to ensure quality and accountability in software development. The rise of technological advances, globalization, and demographic changes poses challenges to maintaining moral values in IT. To uphold moral values, individuals and organizations must prioritize humanistic values over capitalist values and prioritize the collective interest over personal gain. The future of the QA industry depends on addressing these challenges and upholding ethical standards in the face of changing social and economic structures. As the IT industry continues to evolve and face new challenges, we must remain vigilant in upholding ethical standards and protecting the rights and well-being of all stakeholders, so accept the challenge of Anton and join this provocative final session.
Anton Angelov is well-known in the Bulgarian QA community - he is the CTO and Co-founder of Automate The Planet, and also the inventor of BELLATRIX Test Automation Framework, as well as author of two best-selling books, "Design Patterns for High-Quality Automated Tests: Clean Code for Bulletproof Tests" in C# and Java. He is a multiple winner of the "QA of the Year" award, listed in the top 100 of most influential IT people in Bulgaria, and cited with the "Overall Contribution QA Community Award". Anton directs teams of passionate engineers helping companies succeed with their test automation, consults companies, leads automated testing training series, and gives conference talks at the biggest QA conferences worldwide. He has spoken at 40+ conferences globally. Anton has a dream and a vision for Bulgaria to become the world center of Quality Excellence with the right education.
