Tesena Fest 2026

About the Workshop 

As release cycles get shorter, teams need test feedback they can trust quickly. GUI tests are valuable, but expensive. For many scenarios, API tests give better speed, lower cost, and more stable execution - which makes them a strong foundation for CI/CD feedback. 

In this hands-on workshop, we’ll use Claude Code and Superpowers to build a practical API testing workflow. We’ll start from a GitHub issue, let an AI coding agent inspect the API documentation and existing tests, then generate or update automated API tests. You’ll also try how AI can help with work that usually takes time: finding missing coverage, reviewing API contracts, and analysing failed pipeline runs from logs and test artifacts. 

The goal is not to replace your testing skills. The goal is to show how AI can handle part of the repetitive work, while you stay in control of the design, review, and final decision. 

What You’ll Learn 

• How to use Claude Code for API testing tasks  
• How to write GitHub issues that agents can work with  
• How to generate and review API tests from OpenAPI (or any other) documentation  
• How to find missing API test coverage  
• How to analyze failed API tests from CI logs and artifacts  
• How to use Superpowers for repeatable testing workflows  

Walk Away With 

• A working AI-assisted API testing workflow  
• Example GitHub issues for agent-based test automation  
• Reusable Superpower templates for API testing  
• A practical failure analysis workflow for broken API tests in CI  

Who Is This For? 

QA engineers, test automation engineers, developers, and anyone working with API testing. 

You don’t need to be an AI expert. But basic experience with APIs, Git, and automated tests will help. 

What You’ll Need 

Please bring your own laptop. You’ll also need: 

• a GitHub account  
• Git installed  
• Node.js LTS installed  
• a code editor, ideally VS Code  
• ideally your own Claude Code access  

If you don’t have a Claude Code licence, don’t worry - we’ll have a backup setup ready, so you’ll still be able to participate.

About the Workshop 

Many quality challenges today are not technical - they stem from misalignment, unclear ownership, and ineffective communication. Leaders play a key role in shaping how quality is perceived and practiced within teams. 

This workshop explores how leaders can transform QA roles into true Quality Partners who work closely with product, engineering, and business stakeholders to proactively influence quality throughout the development lifecycle. Through interactive exercises and peer discussions, participants will learn how to create the conditions, communication practices, and team dynamics that enable quality to become a shared responsibility rather than a final checkpoint. 

Who is this workshop intended for? 

This workshop is designed for leaders and managers who influence how quality is organized, communicated, and supported within their teams or organizations, including: 

• Test Managers and QA Leads 
• Engineering Managers 
• Product Managers and Product Owners 
• Delivery Managers and Project Managers 
• Heads of QA / Heads of Engineering 

It is especially relevant for those who want to move beyond traditional testing models and enable stronger collaboration and ownership of quality across teams. 

Key Topics  

• Gatekeeper vs. Quality Partner. How to take the first step toward a paradigm shift? 
• Prevent misunderstandings. How to communicate with others and make yourself heard. 
• Team collaboration and communication. We will play a fun game!  
• Team chemistry. How to build (and let go of) a great cross-functional team. 
• The importance of feedback. Feedback as a cornerstone of everything. 
• Influence without authority. Testing typically walks a fine line. How do we get out of this? 

Why join? 

This workshop provides a practical space to reflect on your current approach, learn from others, and explore how to create an environment where quality is built in, not inspected at the end. 

If you want your teams to move beyond testing as a checkpoint and become true partners in delivering quality, this workshop will give you the tools and perspective to make that shift.

Do you think you know test automation. You wrote the scripts. You fixed the locators. You survived the flaky pipelines. You thought you were fast. 

You had no idea. 

This is not a workshop about what AI might do to testing. This is a workshop about what it is already doing and why your current setup is about to look like a Honda Civic at a drag race. 

We go full throttle from minute one. Playwright. Playwright CLI. Playwright MCP. Wopee.io. AI coding agents writing your tests while you watch. AI testing agents running them while you sleep. API testing that does not wait for anyone. 

Same app. Different tools. Head-to-head. You pick the winner. 

Some tools will surprise you. Some will disappoint you. One will make you question every afternoon you spent chasing broken selectors. That moment. That specific moment. It is why you are here. 

By the end of the day you will have built something real, broken something on purpose, and learned more about the new testing stack in eight hours than most teams figure out in a year. 

What you will do 

• Run Playwright the traditional way, then via CLI, then via MCP and see exactly what changes at each step 
• Experiment with Wopee.io as a purpose-built AI testing agent on the same app, same task direct comparison. 
• Wire an AI coding agent to generate, run, and interpret tests autonomously 
• Write a SKILL.md that encodes your team’s testing knowledge so any agent can reuse it 
• Get hands-on with AI-assisted API testing. Same agent concepts, one layer below the UI 
• Build a working test suite your team can actually use next week 

What you will walk away with 

• First-hand experience with the tools shaping web app testing in 2026 
• A working AI-assisted test suite you built yourself 
• A SKILL.md your agent can run cold, without handholding 
• A clear answer to the question your team keeps asking: where do we actually start? 

How the day runs: No death by slides. The day has 4 gears. 

1. The Zoo: 4 exhibits. Same demo app. Playwright CLI, Playwright MCP, an AI coding agent, and Wopee.io. One at a time, side by side. Every tool gets the same fair test.
   
   
2. Teams and mission: Before lunch you get assigned to a team and handed a mission card. Lunch is yours. But your team is already talking.
   
   
3. Build 1 thing: 90 minutes to build a real AI-assisted test suite. Including a reusable capability your agent can run cold, without guidance. This is the thing you take home.
   
   
4. Speed gap battle: 3 new features just shipped on the demo app. Your suite is your only weapon. 45 minutes. Maximum coverage wins.
   
   

Not a fit for you if… 

You have never written an automated test before. This workshop moves fast and assumes basic Playwright or Cypress experience. 

You are looking for a vendor comparison or a product demo. Every tool gets the same fair treatment. Including the ones we built. 

About the Workshop

This updated version of our workshop shifts the focus more firmly toward practical quality engineering skills you can apply immediately. While the core idea remains the same - building quality into your process rather than testing it at the end - we now place greater emphasis on hands-on exercises and real-world application.

You’ll work through a series of focused activities designed to reflect common delivery challenges: balancing speed and quality, working within constraints, improving flow, and making better engineering decisions under pressure. Short theory inputs will frame each topic, but most of the day is dedicated to practice, discussion, and applying ideas to realistic scenarios.

Because every group moves at a different pace, the exact mix of topics will adapt during the day. This allows us to go deeper where it matters most, rather than covering everything superficially.

What to Expect

A dynamic, exercise-driven workshop combining:

• Short, targeted theory segments to introduce key concepts
• Practical group exercises focused on real delivery problems
• Facilitated discussions to connect ideas to your own context

You’ll explore how to:

• Improve flow and reduce inefficiencies in your process
• Identify and manage quality risks early
• Apply modern engineering practices that support quality at speed
• Strengthen team collaboration around quality

Three Things You’ll Take Away:

Practical Quality Engineering Skills
 Techniques you can start using immediately in your team - not just theory.

Better Decision-Making Under Constraints
 How to balance speed, risk, and quality in real delivery situations.

A Clearer Path to Building Quality In
 Concrete ideas for evolving your current approach toward quality engineering.

Why This Workshop?

You won’t just talk about quality - you’ll think about quality differently. You'll leave with the experience and approaches that you can start applying in your own team and environment.
