Tests that tell stories, not implementation details.
Craft tests that survive migrations and refactorings with minimal changes.
Master Fakes and Object Mothers to simplify "mocking" and avoid common pitfalls.
Write reliable e2e tests with Playwright and know when they're the right tool for the job.
Enjoy a buffet of tips and tricks to help you adopt a Pragmatic Testing Strategy.
💬 What they say
As someone beginning to write 'useful' tests, I liked how simple Younes made everything seem. Not a lot of terminology, just a lot of very practical tips. His approach to test doubles provided very practical tips that I will definitely be implementing.
The overview about all the options was awesome. It's great to see how Younes masters all these tools.
Younes is a nice host, very easy going and well explained, well prepared examples and exercises!
Very great presentation about testing. I loved the super fast feedback loop.
Great explanation of differences between mocks, stubs and fakes and how to develop a good testing strategy. The repository with useful examples of different use cases was also great.
I loved developing my own test strategy and seeing a contract test in a real example. Most importantly, I learned about alternatives to the standard TestBed.

🙋 Frequently Asked Questions
Angular developers who write tests — or want to start — and want to improve their testing practices. Whether you're dealing with flaky tests, untestable code, or no testing strategy at all — this workshop is for you.
You should be comfortable with Angular fundamentals (components, services, inputs/outputs), TypeScript basics, and Git. No prior testing experience is required — we start from the ground up.
A laptop with Node.js, Git, and your favorite IDE. Detailed setup instructions are sent a few days before the workshop.
Very. You'll alternate between short theory sessions and practical exercises throughout the three days. Small groups ensure direct coaching and feedback.
The principles and strategies you'll learn apply regardless of your test runner. That said, we use Vitest in the exercises — and you might not want to go back.
Yes. Contact me for a quote and administrative details.
"Book a Session" lets you join a scheduled cohort. "Custom Session" is for companies who want a private, in-house workshop — with optional adjustments to content, duration, or focus areas.
