10:00-10:10 Opening ceremony 
10:10-10:45 Bozhidar Batsov
The Price of Quality  
We start with a different vision towards the meaning and the price of the quality. What is quality and why should we care about it? Is there an universal recipe for creating qualitative products? Who is responsible for the quality of a given product? This adventure is almost as important as searching for the Answer to The Ultimate Question of Life, the Universe, and Everything... In Bulgarian.
10:45-11:00  Coffee-break
11:00-11:35 Svetlin Nakov
Regular Expressions and Their Place in a QA Engineer's Life  
You will get introduced to regular expressions, their syntax and application in practice. Examples will be given on how to validate fields with a regular expression and how to extract data from text using patterns. In Bulgarian.
11:35-11:50  Coffee break
11:50-12:25 Slavy Slavov
6 Common Challenges Setting Up Selenium in High Scale  
Congratulations, you are tasked with setting up Selenium for a few projects so that the test automation can be optimized, scalable, predictable and cost-effective. Sounds hard? It does, because we often bump into pop-up windows, default browser settings, Selenium issues, user certificates, etc. We'll learn how to avoid these problems instead of wasting days on solving them one by one. In addition, we will learn how to scale and maintain the Selenium infrastructure - 6 common challenges which will meet and learn how to overcome. In Bulgarian.
12:25-14:00  Lunch time
14:00-14:35 James Lyndsay
Extracting the truth from a multitude of tests  
One way to understand more about the thing you are testing is to generate thousands of tiny tests and then build a diagram from the results. In this talk, James Lyndsay will introduce you to the ways that he has used simple data and tools to test his own software. You will gain an understanding of this approach by playing with interactive demonstrations. We will talk about techniques for test generation and data visualization, and will highlight the elements of a system that you might approach in this way.
14:35-14:50  Coffee break
14:50-15:25 Veselin Berov
Testing in the World of Information Management  
The information management solutions are specific group of projects which standart testing methods are rarely applicable for. We are going to investigate a case study with a bank application that will put the QA team in front of many challenges: no user interface, big volume of information fetched, and a high speed of processing this data needed. Even more, the calculations made and the system security are critical as we are talking about a bank product. In Bulgarian.
15:25-15:40  Coffee break
15:40-16:15  Show
16:15-17:00  Lightning talks 
17:00-17:15  Coffee break

MythBusters QA Edition: Are Hard Skills Harder Than Soft Skills?  
Undoubtedly technical skills are important, but most often the other ones, the so-called "soft skills" are key to our career growth. At the end of the conference we will learn about seven secret weapons necessary for QA professionals in their daily work so that they can grow and excel in all manner of software projects. In Bulgarian.

Our Cause

The event is organized through Friendly Support Foundation established in public benefit. For more than 10 years Friendly Support Foundation has been putting efforts into developing into accomplished individuals the boys and girls leaving the orphanages in the city of Ruse. At this moment 21 boys and girls live in protected houses where they can obtain skills such as cooking, cleaning and garden work. They also learn many new things and gain valuable life knowledge every day... Half of the surplus funds of the conference will be invested in organizing events like QA:Challenge Accepted and the other half - given to charity for the needs of the young boys and girls in the protected houses in Ruse.
