In modern microservices, reliable communication isn’t guaranteed — especially when services don’t even share the same protocol. End-to-end tests are often too slow, brittle, or costly to catch every issue. That’s where consumer-driven contract testing comes in.

This session demonstrates how Pact can act as the matchmaker between a Spring Boot REST consumer and a gRPC provider in .NET. You’ll learn how to define and validate contracts across languages and frameworks, bridge protocol mismatches, and evolve contracts safely as systems grow.

A live demo will show contracts being created, verified, and integrated into CI/CD pipelines. Practical techniques for handling versioning, managing multi-language environments, and avoiding late integration surprises will be shared.

Whether you’re scaling a distributed architecture or just exploring contract testing, you’ll leave with actionable strategies to make heterogeneous systems more reliable, speed up feedback loops, and enable smoother collaboration between development teams.

Modern software systems rely on large graphs of interdependent microservices maintained by multiple engineering teams. Nightly integration tests frequently expose failures in these systems, yet determining which team should investigate first remains a largely manual and error-prone process. Misrouted incidents lead to cross-team ping-pong, increased MTTR, operational friction, and wasted engineering time.


This paper presents MANTHOS (Microservice Alert Navigation & Triage Handoff Optmization Service), a probabilistic, cost-aware incident routing engine designed to automatically assign integration test failures to the most appropriate team. MANTHOS combines (i) a service dependency graph, (ii) diffusion-based prior estimation for likely upstream faults, and (iii) multiple operational evidence signals—including stack traces, recent code changes, service flakiness, and optional deployment or performance anomalies. It aggregates service-level probabilities into team-level responsibility and selects a recommended assignee using an expected time-to-recovery (TTR) optimization model that incorporates team responsiveness, current load, ownership alignment, and a synergy matrix capturing historical cross-team coordination patterns.


We evaluate MANTHOS on historical integration failures and demonstrate significant reductions in misassignment rates, unnecessary handoffs, and median TTR. The system integrates easily into CI pipelines, Slack/Jira workflows, and SRE tooling, providing transparent, explainable recommendations. Our results show that probabilistic inference combined with lightweight operational signals can materially improve dependability practices in complex service organizations. MANTHOS offers a structured, data-driven alternative to manual triage and serves as a practical foundation for next-generation AIOps tooling.

Present and explain the architecture of the environment that in our company we are running Android tests on daily basis in a local device farm with real devices and emulators. How we prepare the devices and the APKs prior to test executions using Appium in docker containers, custom scripts and workflows in GitHub Actions. Run parallel tests on multiple releases (current + 2 prior versions) to ensure backwards compatibility.
Thus it will be helpful for someone that wants to start to have automated tests for mobile apps to see that it’s feasible and not that time consuming. Also a test automation engineer will learn how to integrate Appium-based testing directly into their CI/CD workflows.

In an era where digital banking is rapidly evolving, ensuring the highest quality standards in software development is not just an option, but a necessity. This talk will explore the crucial role of Quality Assurance (QA) in the neobank landscape, focusing on strategies to streamline QA processes and enhance overall efficiency.
 
Attendees will gain insights into:
 

1. Understanding the Neobank Ecosystem: We'll discuss the unique challenges and opportunities faced by neobanks, including the need for rapid innovation, regulatory compliance, and user-centric design.
2. Establishing a Robust QA Framework: Learn how to build a comprehensive QA framework tailored for neobanks, incorporating best practices for automated testing, and continuous integration.
3. Leveraging Automation and AI: Explore the latest tools and technologies that can automate testing processes, from functional testing to performance and security testing, thus reducing time-to-market while maintaining high standards.
4. Collaboration and Communication: Discover effective strategies for fostering collaboration between QA teams, developers, and other stakeholders, which is vital for ensuring seamless product development and early detection of issues.
5. Metrics and Continuous Improvement: Understand the importance of using metrics to measure QA effectiveness and drive continuous improvement in processes and team performance.
6. Case Studies and Real-World Examples: The talk will include case studies from our successful neobank Snappi that have implemented streamlined QA processes, sharing lessons learned and best practices.

 
Join us for this insightful session to learn how to effectively streamline your QA processes, enhance product quality, and deliver exceptional digital banking experiences that meet the demands of today’s consumers. Whether you're a QA professional, developer, or a leader in the fintech space, this talk will equip you with actionable strategies to thrive in the competitive neobank landscape.
