TDD подход к разработке зарекомендовал себя как очень надежный и быстрый способ реализовать задачи бизнеса с помощью программного кода. Но большая часть примеров на тренингах и в интернете показывает как применять TDD в очень простых ситуациях для кода вида вход/выход или с использованием заглушек для простых зависимостей. А как насчет остальных областей разработки приложения как интеграция с БД? Возможно ли применить TDD к ним? Что даст в этом случае TDD разработчику? Я попробую в своем докладе ответить на эти вопросы и покажу на практических примерах как может быть полезен подход TDD для кода интеграции с БД, как он уменьшает риски и открывает двери для техник рефакторинга БД. В качестве бонуса будут затронуты некоторые NoSQL решения, что должно сделать тему еще популярнее! P.S. Все примеры будут демонстрироваться на Java.

Do you know what you are testing?

Automated UI Testing

Mikalai Alimenkou

Almost every Java developer knows ORM concepts and Hibernate as the most popular solution in Java world in this area. But it is big surprise that very small percent of Java developers (even experienced ones) can answer very simple questions about how Hibernate really do all this “magic”. In this live coding session we will go through many practical samples and finally show truth to the Java community. ;) P.S. After this talk you could pass through any Senior Developer interview easily. Code samples can be found here: https://github.com/xpinjection/hibernate-basics .

Java concurrency in practice

Mikalai Alimenkou

Every Java developer knows that multithreading is the root of all evil and it is quite hard to write correct code for concurrent environment. But what tasks do exist in real commercial development except running code in asynchronous way? In this talk I will present several tasks from my real projects and solutions we designed for them. This talk is very application oriented and allows participants to extend their vision of concurrent programming.

Web automation with Selenium for software engineers

Mikalai Alimenkou

We all know Selenium/WebDriver more as testing automation tool. But in reality this is just a tool/library to automate operations with different browsers using similar API from different languages. In this talk I will show how to use different parts of Selenium product family for day to day tasks of developer, QA engineer or even Project Manager. Hope after visiting this talk you will spend less time on boring procedures and improve many things in your current development process.

How to make your functional tests really quick

Mikalai Alimenkou

Functional tests are usually the slowest layer of automated tests for almost every product. They use product via UI, store data in real DB, integrate with external services and do other “slow” things. The first easy answer how to make them fast is to run in parallel. But in reality tests depends on the same data and intersect by some common functionality. In this talk we will review useful techniques and approaches how to win this battle.

Java 8, the Good, the Bad and the Ugly

Mikalai Alimenkou

Java 8 is being around for a while already and lot of us are already using Java 8 features on our projects. But do we use these great Java 8 features correctly and efficiently? Having done lots of code reviews during last years we’ve seen some common antipatterns of Java 8 features usage. In this talk we want to show you some of the examples where Java 8 features were misused or poorly used and show you how certain things could have been better implemented.

Hibernate performance tuning

Mikalai Alimenkou

Many Java developers use ORM in their projects but most of them don’t do deep dive into configuration, settings and tuning to achieve really good performance. What is worse most of them even don’t know what options do they have to improve performance. In this talk we will review them on practical samples and give concrete recommendations how to make your Hibernate work much better in real projects. Code samples can be found here: https://github.com/xpinjection/hibernate-performance .

Бытовая классификация тестировщиков с точки зрения разработчика

Mikalai Alimenkou

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!

Rise and fall of Story Points. Capacity based planning from the trenches.

Mikalai Alimenkou

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

Mikalai Alimenkou

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

Mikalai Alimenkou

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

Mikalai Alimenkou

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.

Ride the database in JUnit tests with Database Rider

Mikalai Alimenkou

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

Mikalai Alimenkou

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

Mikalai Alimenkou

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…

Mikalai Alimenkou

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]

Mikalai Alimenkou

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

Mikalai Alimenkou

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.

Code Review tool for personal effectiveness and waste analysis

Mikalai Alimenkou

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

Mikalai Alimenkou

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.

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. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Elevating Tactical DDD Patterns Through Object Calisthenics

Dorra BARTAGUIZ

After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Removing Uninteresting Bytes in Software Fuzzing

Aftab Hussain

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. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs

Alex Pruden

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).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
