How to be a Happy Developer. Now! by Christian Robert
A lot of developers will agree to the claim that they turned their hobby into their profession. However, when looking at the daily business they often face a world very different from what they expected. A variety of reasons lead to increasing frustration. For some it’s company politics, for others it’s crazy customers or technologies that we’ve been forced to work with. All of this leaves us thinking “What the hell am I doing here?”. When trying to do something about this we often hear or read a lot of interesting concepts of how to improve our working environment like: “Do scrum!”, “Convince your leadership to give you more slack time”, “Use framework X” or “Follow the latest trend Y”. While this sounds nice at a first glance, real change is a lot harder. So, what can we do to improve the current situation? How can we make ourselves feel better? This talk focuses on some easy to implement tactics, that each and every one of us can use from tomorrow on, making our life a little bit easier and more enjoyable: piece by piece, day by day.

GitHub Actions: Open Source Workflow Automation by Bas Peters
In this talk Bas Peters will give an overview and demo of GitHub Actions. GitHub Actions are a new way to automate your workflows as code hosted, shared and executed on GitHub.com. GitHub Actions apply open source principles to workflow automation allowing you to share and discover actions to use in your workflows. You can use them to build and test your code, to package and deploy, to send notifications on specific events like creating a release or to automate welcoming new users to your open source projects. We think GitHub Actions are going to have a big impact on software development and we would love to hear your feedback and ideas.

Tamir Dresher - Testing and Time and Concurrency With Rx.NET Schedulers
TestCon Moscow 2017 Conference, April 27. www.testconf.ru Working with asynchronous services has always been a desirable approach and a necessity when creating a responsive, Connected, Data-intensive application. Today, when every application needs to work with sources like Facebook, Twitter, device sensors and Cloud Services, this task become harder and harder. Even harder than creating such applications is testing them for scenarios that involve time and concurrent processing. Reactive Extensions (Rx) makes this easy, with the concept of parameterized concurrency with Schedulers and Virtual Time. In this session, you’ll understand how reactive programming with Rx.NET can simplify your code and tests.

Better, Faster, Stronger - Delivering High Quality Products by Finn Lorbeer
Did you know you can enable your team to build better software faster while having a stronger team culture? Too good to be true? In recent years, agile has influenced early involvement of testing in the development cycle. With this more and more testers are testing new functionality as soon as a commit is pushed. Yet such teams still fail to deliver high quality software. Why? What is missing? Working with various diverse teams across multiple projects, Finn realised that testing doesn’t actually improve software quality. It’s just a bar assuring a certain level of quality that already exists. In order to actually improve we must get involved into much more than simply testing and think about the product as a whole. In this session, Finn will share specific examples of how engaging with the business, engineering, process optimisation as well as the entire cross-functional team can lead to significant improvements in the product’s quality. At the end of the talk, you will know how to start with a holistic approach to improving product quality throughout the entire software delivery lifecycle.

Agile Leadership by Zuzi Sochova
In order to change organization, leaders have to change first. Be one of them and turn your organization into the successful Agile organization. Organizations are constantly evolving, they change their structures, processes, and rules. Last decade they’ve been changing into Agile, and surprisingly despite all the effort and money they put into transformation, they’ve been often failing. The same way as culture follows an organization, the culture follows leaders. Companies were trying to break that rule for years and change the culture without changing leadership style. Nowadays this rule seems to win and organizations are moving towards different leadership styles and surprisingly becoming successful. In order to change organization, leaders have to change first. Be one of them and turn your organization into a successful Agile organization.

Nicolae Oprean - Code Review for Test Automation
TestCon Moscow 2017 Conference, April 27. www.testconf.ru For developers, Code Review process has been essential for ages. It has been proven that it detects more bugs than any other form of testing, improves code quality, fosters knowledge sharing (for both the reviewer and the reviewee) and is cost effective. Code review can also be used successfully in Test Automation which will strengthen the collaboration between technical and functional specialists (Developers and QA). Nicolea will present our techniques for Test Automation Code Review; although it’s not the entire recipe, following them is an ingredient for better test code (clean, readable, simple, robust, bug-free, extendable…).

Opening Keynote: Blunders in Test Automation by Dorothy Graham
In chess, the word blunder means a very bad move by someone who should know better. Even though system-level functional test automation has been around for a long time, people still make some very bad moves and serious blunders. The most common misconception in automation is thinking that manual testing is the same as automated testing. And this thinking accounts for most of the blunders in system level test automation. Dorothy Graham takes us on a tour of these blunders, including: Testing-Tools-Test, Silver Bullet, Automating the Wrong Thing, Who Needs GPS, How Hard Can It Be, the Stable-Application Myth, Inside-the-Box Thinking, the Project/Non-Project Dilemma, and Isolationism. Different skills, approaches, and objectives are needed or you’ll end up with inefficient automation, high maintenance costs, and wasted effort. Join Dot to discover how you can avoid these common blunders and achieve valuable system-level test automation.

What it Takes to Become a Performance Engineer? by Canberk Akduygu
Performance engineering is a discipline where one has to deal with many technological challenges. While manual and automated testing deals with the UI or business layer of an application, performance testing deals with low-level issues. That bring us the challenge of being a technical test engineer. What technology stack should we concentrate? What development language should we choose, etc?

Closing Keynote: Examples of How to Move towards Zero Defects by Niels Malotaux
How many defects should the users of our software find? How many issues do you accept the users to experience? If you agree that it should be “Zero!”, then we can discuss how to achieve that. If you think it’s impossible, better attend and learn, to avoid being put out of business by those who are delivering Zero Defects. Some people think that we can produce better quality by better testing. Wrong! The most economical way to produce quality is by preventing any problems to creep in in the first place, making sure the users don’t experience any hassle. We’ll discuss a few cases where we used techniques that helped people move towards Zero Defects, like: design, review, the DesignLog, short-circuiting, and using “No Questions, No Issues” as a final test requirement. Zero Defects often is dismissed as an impossible dream. My experience tells otherwise. It doesn’t mean “turning a switch and then we don’t produce bugs anymore”. What it does mean you will find out in the keynote.

Jenkins Scaling and Organization for an Efficient CI by Andrea Giardini
We can’t discuss automation and DevOps without discussing Continuous Integration and Deployment. At Camunda, we develop open-source software for workflow automation and, over the years, we’ve built an extensive CI/CD system based on Jenkins. Today our biggest instance has more than 2,500 jobs. On top of that, our other projects manage Jenkins instances autonomously, relying on Kubernetes. Reaching this scale was a challenge in terms of organization, performance and scalability. The infrastructure team at Camunda had to evaluate different solutions and find ways to manage such a complex scenario, while giving developers the right degree of freedom and trust. During his talk, Andrea will explain how his team is able to manage all these environments and which approach they found most successful for their use case.

Apache Metron in the Real World - Big Data and Cybersecurity, a Perfect Match by Dave Russell
In this session we’ll be looking at a number of different organisations who are on their big data cybersecurity journey with Apache Metron, we will take a look at the different usecases they are investigating, the data sources they used, the analytics they performed and in some cases the results they were able to find. We’ll also spend some time talking about the common themes in these projects, there are some common approaches to using Apache Metron as a phased project in a project, we’ll review some of the common pitfalls and give some concrete suggestions about the things you should (and shouldn’t) do when you’re getting started. Finally we’ll try and tackle some of the key FAQ’s that come up when people are first investigating the potential usage of Apache Metron in the real world based on over a year of interacting with customers and prospects as they look deeper into Apache Metron to see how it fits in to their cybersecurity portfolio.

Alexei Vinogradov - KISS PageObjects
TestCon Moscow 2017 Conference, April 27. www.testconf.ru Page Objects is probably the best-known pattern for UI Automation in Testing. Still implementing the Page Objects can be tricky in many ways even for the most typical web application. Alexei will introduce 3 types of PageObjects implementation (“Static”, “Void” and “Fluent”), which he has successfully used in his projects and explain their advantages and drawback. He will also explain why some other/additional patterns you can find in blogs/books or even get recommended in conference talks are actually no good. Warning: some pieces of advice may look provocative or even change the way you look at designing UI tests completely! The session will show Java Code examples (Selenium/Selenide) highlighting the implementation details.
