How to Test Microservices Without Going Crazy 🧩 Microservices change not only architecture, but also how we test. A service can work perfectly on its own while the whole system is broken. The biggest risks often appear at service boundaries: incompatible contracts, changed schemas, timeouts, retries, duplicated messages, and unexpected assumptions. A balanced strategy looks like this: 🧪 Unit tests → business logic 🔌 Integration tests → realistic interactions 📜 Contract tests → service boundaries 🌐 E2E tests → critical user journeys 📊 Production validation → real-world behaviour Don't make E2E tests responsible for everything. A few critical scenarios can provide more confidence than hundreds of fragile E2E tests. The goal isn't to have the maximum number of tests. It's to have the right tests answering the right questions at the right level. 👉 Read the full post on LinkedIn What would you add to this testing strategy?

A green CI/CD pipeline doesn't mean your system is production-ready All tests can pass while users are stuck on a loading screen. Most production incidents aren't caused by bugs in your code - they happen when the environment fails: • slow databases • flaky networks • third-party API outages That's why Chaos Engineering matters. Instead of asking "Does it work?", it asks: "What happens if a critical service fails right now?" Companies like Netflix even created Chaos Monkey to randomly terminate production instances and continuously verify system resilience. Because users don't care if your pipeline is green - they care that the app still works when everything around it doesn't. How does your team test resilience?

📢 What if personal branding doesn’t start with content? In the age of AI, anyone can create content. 🤖 But a strong professional brand is still something that can’t be generated with a single prompt. Most professionals follow the same familiar path: 📦 Choose a niche → 🎯 Define your positioning → 📱 Publish content consistently → ✨ Look like an expert But what if that's not where you should start? Join us on July 29 in Warsaw or online to explore how to build a professional brand from the inside out — through your strengths, values, and professional identity. ➡️ Registration: here 💡 Learn why traditional personal branding advice is losing relevance, how AI can help with self-discovery (not just content creation), and how to turn your unique strengths into clear professional positioning. ⏰ Time: 18:30 (CEST) ⏳ Duration: 1 hr 🗣 Language: English 📍 Offline: Andersen’s office in Warsaw 💻 Online: The link will be sent to the email address provided during registration Andersen IT Community

Finally, an honest changelog

🤖 AI is lowering the barrier to cyberattacks. A new concept is emerging: VibeHacking - using AI to discover and chain vulnerabilities through natural-language prompts instead of writing exploits from scratch. This shift means: 🔹 Complex attacks are becoming accessible to less experienced attackers. 🔹 AI-generated attack techniques can rapidly adapt to different environments. 🔹 Defensive teams will need AI-powered detection, threat hunting, and automated remediation to keep pace. The cybersecurity landscape is changing faster than ever. 📖 Read the full article and join the discussion on LinkedIn
