What to expect

John Atanasoff Forum, Sofia Tech Park, Sofia, Bulgaria
What to expect from QA: Challenge Accepted

Single conference track means that you will be able to attend all of the lectures without having to worry that you can miss something interesting. Everything happens in the main hall. Still, there are plenty of other things to do around.

Distinguished speakers and topics are carefully chosen by the organizing commitee. Some of the best professionals in the sector will present interesting and actual problems in QA (as well as their solutions) with real, practical usage.

Work & fun combined means exactly that! It has been proven that people learn better when they have fun. Thus, besides the technical part of the conference you can expect interesting games and raffles, awards and surprises, and many more.

Afterparty will be held immediately after the official closing of the conference, so reserve some time for a few beers, joyful conversations and endless opportunities for networking. You definitely don't want to miss it.

  09:50-10:20 When start-up meets quality... A short story of QA agent

You cannot just face exactly the same problem again joining the new company, can you? This rule however does not apply to the start-up environment. Dawid has worked for three different start-ups so far, always getting on board with a clear mission in mind - to increase the value of the product by building a proper quality mindset and culture within the whole organization. The companies differed in almost every aspect: industry, structure, maturity, business approach and technological advancement. The one and only thing in common always was a single tester clicking for a few years already. During that time, the companies were growing and scaling up. A gateway to disaster! And here is how the story begins. Dawid will share his story of becoming a change agent of Quality Assurance: the mistakes made, the lessons learned and the solutions implemented, in a nutshell.

Dawid Pacia

Dawid describes himself as 1/3 QA, 1/3 Python, 1/3 Lead. Dawid is also a tech freak following all the newest technologies (and implementing them on his own). Fan of the Agile approach to project management and products, Dawid leads and supports a wonderful QA team, actively speaks (and travels) around the world (combining both passions). Dawid is also an organizer and originator of the first regular Ukrainian QA meetup - “UkrainQA”. He has already spoken at the previous edition of QA: Challenge Accepted. Last, but not least: Dawid is a big cat lover!

  10:20-10:40 Coffee break


  10:40-11:10 Cutting edge technologies in automated testing

We will continue with Anton, and he will brief us about many of the most modern solutions for visualizing test results and executing tests in Docker containers. Also, we will review many framework integrations with cloud cognitive services which use machine learning ML and artificial intelligence AI. Finally, we will review how to use them for testing hard otherwise functionalities such as PDFs or videos. The demos will include testing of voice, optical character recognition OCR, and others.

  12:00-12:20 Coffee break


  12:20-12:55 The bug is not enough!

Imagine a project with 200+ defects, 1000+ tests, no clear architecture map and almost no knowledge over the product. How can we find the most impacted areas by our developments for a milestone/service? How many tests should we run for each impacted area? If we have automated tests, shall we execute manual tests, too? Victor has a personal story to tell that will give us the answers to all of these questions, and can become a guideline in creating a better test strategy.

Victor Ionascu

Victor is passionate about testing for 12+ years. During that period he had the chance to experiment many approaches and fail quite often. The good part of the failure is that you learn a lot of things, and this helped Victor to organize better the process around the quality topics. Victor is currently working on integrating multiple products into a viable solution with a very good level of quality. In addition to this, Victor has already spoken at many international conferences. Outside his job he likes enjoying a glass of wine after a good hike, or a cold beer near the seaside.

  13:40-14:10 Code-driven load testing with k6 Framework

Load and performance testing aims to determine whether software meets speed, scalability and stability requirements under expected workloads. Old school performance testing tools like Apache JMeter are complex and heavy and are not well aligned with the modern QA automation and continuous integration trends. In this talk Svetlin will present and demonstrate the "k6 framework" - a modern open-source load testing tool, which describes the load tests as JavaScript code. The k6 tool is very powerful, high-performance and developer-friendly. It allows load testing of Web apps and APIs, accessed through the HTTP protocol. Svetlin will also demonstrate how to install and use k6, how to run its test recorder, how to edit the recorded scripts at the k6 cloud and how to write k6 scripts in JavaScript (execute HTTP requests, write checks, define thresholds), and execute the scripts with certain number of virtual users for certain duration.

Have you ever started a car engine remotely? Not yet? Then let’s see how easily you can run the engine of a vehicle situated at Sofia Tech Park from Germany, for example! The presentation traces how the standard process has been automated and upgraded with an implemented real car in place of a simulated one. The goal is to test the software as quickly and closely as possible in a real car, from the test engineer's and user's perspective. Pavel will share his experience and will also make a demonstration on how a real prototype car is transforming into a device under test.

  16:20-16:40 QA - Misunderstood Demiurge and Team Psychologist

During the lightning talks of the last year's edition of QA: Challenge Accepted, some people shared that they were not feeling well and how they got away from their work. Teodora wants to justify the significant place of the QA in SDLC and in the team. She will share her experience that helped her to become a full member of the team for two years: the way to deepen knowledge and skills to contribute for improving the quality of the software we produce, and what psychological knowledge to have and apply, so that the work with the other members of the team is efficient and effective. Teodora's experience as a philosopher and a teacher helps her to have a better view of the product being developed, on one hand, and on the other hand, to better understand the working atmosphere. So, she can share her experience on how to become a better QA and how to improve mutual work with developers.

Teodora Nikolova

  17:00-17:40 How to fake testing like a Pro

Aren’t you tired of countless hours where you have to work your abs off? The never-ending need to constantly prove, evolve, and improve your skill set? Isn’t it a pain and an annoyance that you have to always be diligent, knowledgeable and accountable for your work and testing all the time... and work hard... 8 hours a day, 5 days a week!? Wouldn’t it be lovely if there was an easier way? And there is! Viktor will present us the ground-breaking, eye-opening, mind-shifting, paradigm-shattering concept of “How to fake testing like a Pro”, a revolutionary framework that will teach you how to hack your working style and fake your testing job in a way that will make it appear as if you are the most performing tester in the team without breaking a sweat. You will have to only invest little to none effort to maintain it, and the results will be mind-blowing. You will be “The next big star” on the team, you will probably even get a promotion. All of that with no time, effort or money invested. You will have all of your free time to invest in more valuable activities such as: drinking coffee with friends and colleagues, browsing 9GAG and cat videos on Youtube, arguing with random people on social media and playing Heartstone while on the toilet seat. Join Viktor in the last talk, and he will change your life and career forever!
