Continuous Delivery
Presentation from XP Days Ukraine (December, 2011) about establishing continuous delivery process in development team
Rise and fall of Story Points. Capacity based planning from the trenches.
Люди в мире Agile используют Story Points - для Agile коучей и тренеров это самый простой способ объяснить, как следует проводить оценку и планирование в «новом мире». Но тогда эта простая концепция нарушает реальные практические кейсы. В настоящее время команды состоят из очень специализированных людей, работающих над бэкендом, фронтэндом, тестировании, инфраструктуре и прочим. Для них почти невозможно иметь общий уровень сложности. Это только одна из проблем, которые мы собираемся осветить в этом докладе.
Чтобы оставаться конструктивным, а не просто старомодным парнем из XP, Николай поделится своим опытом с более точной и прагматичной техникой оценки/планирования - планированием на основе возможностей.
Static analysis tools as the best friend of QA
We have spent many years testing our applications and systems manually and with test automation tools. During this time many bug root causes have been classified and could be detected automatically with special static analysis tools. Most of them could be applied at the early stages of development even before code is integrated into the main development branch. In this talk, I will go through available solutions and demonstrate what kinds of issues may be detected automatically reducing the time and effort of traditional testing.
Modern CI/CD in the microservices world with Kubernetes
In this talk, we will go through the design process of modern CI/CD for the microservices-based system with Kubernetes support. We will discuss how to verify consistency between microservices, apply different levels of quality gates and promote artifacts between environments. Thanks to Kubernetes we will review different approaches of environment resources optimization for development needs during CI/CD cycles.

Saga about distributed business transactions in microservices world
Most of people nowadays think microservices architecture is a great way to build any system. They visit conference talks, read books and review tutorials, where ‘hello world’ applications are built just in several minutes using microservices approach. But the reality is not so wonderful and one of the biggest pain is hidden inside distributed business transactions. In monolith application this topic is almost completely covered with DB level transactions. In distributed world you have to face many issues trying to implement reliable and consistent business logic.
In this talk we will review different types of problems related to distributed business transactions, popular SAGA pattern, frameworks and techniques to simplify your life without compromising quality of the system.
Effectiveness tips from Kubernetes trenches by Captain Obvious
Nowadays almost everybody knows about Kubernetes, some teams are using it and some are only dreaming about it. Despite the popularity, Kubernetes is not simple and there are so many ways of abuse this peaceful technology. In this talk I would like to present quite obvious set of tips, based on failures and ineffectiveness at different companies I have worked with during last several years.
Ride the database in JUnit tests with Database Rider
For a long time DB related testing in Java world has been a real pain and most developers tried to reduce number of such tests as much as possible. With good in-memory database implementations like H2, schema migration solutions like Liquibase or Flyway, containerization with libraries like TestContainers, database management is now much simpler. But test data management is still a pain. Some developers use SQL dumps, others insert data via JPA/JDBC or rely on prepared data sets. Good old DBUnit may be a good option, but it is not so developer friendly and not adopted well for modern annotations driven development style. Database Rider closes the gap between modern Java development environment and DBUnit, bringing DBUnit closer to your JUnit tests, so database testing will feel like a breeze. In addition to flexible data sets management this library provides other useful features: programmatic data sets definition, leak hunting, data sets export, constraints management, etc. As contributor and loyal user for many years, I would like to share my experience with Database Rider and demonstrate how to make database testing a fun again!
Wastful waste or why everything is so slow in development
I think almost everybody experienced cases when things are moving very slowly in IT companies or teams. You have many people, talented engineers, Agile process and development speed is still below expectations. We try to focus on performance and efficiency last 10 years, improving our practices and tools. But we are still there in terms of speed when they are applied to real life cases. How is it possible? In this talk we will review the concept of waste circles and understand what are the main sources of time waste in development process. This concept would help you to check your processess, focus on right things and achieve much better results in your organization or team.
Hexagonal architecture with Spring Boot
Nowadays traditional layered monolithic architecture in Java world is not so popular as 5-10 years ago. I remember how we wrote tons of code for each layer repeating almost the same parts for every application. Add unit and integration testing to understand how much time and efforts has been spent on repeatable work. All cool ideas around DDD (domain driven design) and Hexagonal Architecture was just a nice theory because reality hasn’t allow us to implement it easily. Even Dependency Injection with Spring framework was completely focused on traditional layered approach, not even talking about JavaEE platform.
Today we have Spring Boot ecosystem covering most of our needs for integration with almost all possible technologies and microservices architectural trend, enabling completely new approach to build Java applications around domain model. It is so natural to build Java domain-oriented services and connect them with external world using ports and adapters, that Hexagonal Architecture is almost enabled by default. You just need to switch your way of thinking…

DevOps checklist or how to understand where is your team in DevOps landscape ...
DevOps become a buzzword in a last few years. Several companies, development and product teams have achieved quite impressive results in this area making cultural changes, transforming their processes and practices, introducing new roles, tools and techniques.
Do you think is achievable for you team or it’s still a bunch of drama? There is no common approach for measuring achievements and understanding how much DevOps’ich the current team/company is. In this talk I will provide attendees with basic checklist to start with and some reliable tools/techniques to monitor progress of “DevOps transformation”.

Bro, manage test data like a pro! [QA Fest 2018]
Almost any application or software system manages data. It is hard to imagine test automation that is not affected by this fact. There are many differenct approaches how to prepare system under test, providing predefined test data: use application UI, invoke API methods, run business logic directly, access DB from test scenarios, etc. In this talk we will review most of existing approaches, starting from the easiest and the most popular ones and finishing with really tricky ways to manage your test data for large distributed systems. There is no ideal solution for every case or silver bullet, but I hope your toolset will become wider after visiting this talk.
Agile antipatterns: review after 10 years of practice
Вот уже более 10 лет Agile движение шагает по Украине и стучится практически в каждую компанию. Но приносят ли новые процессы, принципы и практики реальную практическую пользу? Получается ли изменить к лучшему команды, проекты, компании? Я в роли консультанта за эти 10 лет поработал с более чем 100 компаниями, поэтому повидал много хорошего и плохого. В данном докладе хочется пробежаться по основным проблемам, сложностям и анти-паттернам в переходе отечественных компаний на "Agile рельсы". Мы рассмотрим какие практики не очень хорошо приживаются, от чего страдает большинство команд, какие основные препятствия встречают на своем пути и как умудряются их обходить. Я надеюсь, доклад поможет зародиться множеству интересных дискуссий.

Бытовая классификация тестировщиков с точки зрения разработчика
Тестировщики часто говорят о противостоянии и конфликтах с разработчиками. Но ведь есть команды, где все живут в мире и согласии. Видимо что-то тут не так? Я хочу поговорить о том, как тестировщиков видят сами разработчики. В докладе будет проведена забавная классификация. Кроме известного всем тестировщика-обезьянки будут представлены тестировщик-муха, тестировщик-нацист, тестировщик-панда и многие другие герои. Высможете лишний раз задуматься над тем, как вас видят со стороны и, возможно, изменить ситуацию к лучшему.
Доклад будет также полезен менеджерам проектов и лидерам команд. Вы сможете быстрее распознавать те или иные шаблоны поведения тестировщикови принимать меры по повышению уровня командной работы. Приходите, будет интересно!
Code Review tool for personal effectiveness and waste analysis
Usually it is hard to analyze personal effectiveness and detect wastes in development process because developer’s work decomposition is not transparent and available for analysis. As a good sample of ineffective process imagine developer, who spends 1 day on task implementation and then reimplements it several times according to code review notes during next 2 days. Or another developer, who is waiting for code review during 2 days, switching context to other tasks, finally gets notes and switches back to initial task, trying to refresh all details in his head. And so on and so forth…
Code review tool usage helps to aggregate lots of useful information about any code change at any stage (static analysis, code review, rework, acceptance, integration into main branch). In this talk I’m going to demontrate how this information could be used for detailed analysis of development effectiveness and wastes detection. Based on mentioned analysis you could implement many improvements for your development process and then measure their success.
Funny stories and anti-patterns from DevOps landscape
During last several years DevOps became strong buzzword used almost in every project, team and company. But almost everywhere it is used in very funny and strange context. For example, existing ops guys are renamed to DevOps just to sell them to the client for more money. Or DevOps is used as new job title for some magically powerful person who is able to operate cloud environment and modern infrastructure related tools, leading team of old school ops and participating in management meetings. In this talk I’m going to review all different anti-patterns and bad practices in DevOps landscape using stories from my personal experience as Delivery Manager and independent consultant.
Developer + tester = quality++
With Agile adoption many things have changed in quality assurance and tester role. Ourdays the whole team is responsible for product quality. But not so many people understand how such high level approaches work in practice, how developer interacts with tester, what stages each task passes on the way from requirements specification to customer acceptance, who is doing what at each stage.
I have met only few teams, where developer and tester work closely together on a daily basis. Some projects try to same money on developer's time, others try to have independent testing team without influence from developers side. Developers also don't understad how tester could help them in practice. But this pair is able to significantly improve product quality and avoid many common issues.
In this talk we will cover motivation behind pair work of develoeper and tester, concrete practices and approaches at different stages, and advantages that both sides could achieve from such work style.
Continuous improvements of developer efficiency with modern IDE
Nowadays IDE are much more intelligent than 10 years ago when they played mainly code editor functions. At the same time number of good practices and techniques is growing from day to day and most developers don’t have time to learn them with the same pace. So it could be a good idea to use IDE as continuous learning tool. In this talk we will cover following areas of developer efficiency: automated refactorings, live templates, useful suggestions, code standards, code navigation, code generation… I hope after this talk your daily job will become much more effective.
Design patterns in test automation
Design patters exist for years in software development. Some developers love them, some think they are useless. But design patters has very clear goals: describe common solutions for common problems, create shared language for community, improve understanding and reuse of existing approaches. Test automation has its own set of problems, so there is a set of helpful design patterns for this area. In this talk I will run through all known patterns and describe them in details with several practical samples.

Continuous improvements of developer efficiency with modern IDE
Nowadays IDE are much more intelligent than 10 years ago when they played mainly code editor functions. At the same time number of good practices and techniques is growing from day to day and most developers don’t have time to learn them with the same pace. So it could be a good idea to use IDE as continuous learning tool. In this talk we will cover following areas of developer efficiency: automated refactorings, live templates, useful suggestions, code standards, code navigation, code generation… I hope after this talk your daily job will become much more effective.
Design patterns in test automation
Design patters exist for years in software development. Some developers love them, some think they are useless. But design patters has very clear goals: describe common solutions for common problems, create shared language for community, improve understanding and reuse of existing approaches. Test automation has its own set of problems, so there is a set of helpful design patterns for this area. In this talk I will run through all known patterns and describe them in details with several practical samples.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Epistemic Interaction - tuning interfaces to provide information for AI support
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
