AI testing is 80% about passing metrics and 20% about actual quality. Most teams have this backward. Ever wonder why some AI models ace all their benchmark tests but fail spectacularly in production? It's because we're often measuring the wrong things. 📊 When testing AI models, I've learned that TP, TN, FP, FN only tell part of the story. They're like checking if a car has all its parts without seeing if it actually drives well on the road. AI Testing The real challenge is designing tests that simulate how users will break your system in ways you never imagined. Precision and recall might look perfect in your test environment, but real-world data is messy, biased, and unpredictable. F1 scores are helpful guideposts, but they're not the destination. I've found that balancing these metrics with qualitative human evaluation creates the most robust testing approach. 🧠 What metrics beyond the standard accuracy measures do you find most valuable when testing AI models?

Feeling stuck in your testing career? I once spent nights wondering if I should leave QA entirely.  Then I realized each role—even the challenging ones—was teaching me valuable lessons I couldn't have learned elsewhere. Career growth isn't always about climbing upward. Sometimes it's about absorbing diverse experiences that build a unique perspective.  My journey across different companies shaped my approach to quality in unexpected ways. 🔄 As a test engineer early in my career, I learned the fundamentals of systematic validation and the satisfaction of finding critical bugs before users did. This built my technical foundation. Leading automation at a technology company taught me the power of frameworks and reusable components. Designing a Page Object Model Framework increased efficiency by 40% and showed me how architecture decisions impact long-term success. Perhaps most valuable was my time at a SaaS provider, where I learned to balance speed and quality in fast-moving environments. Reducing defect rates by 95% while maintaining rapid releases shaped my understanding of risk-based approaches. Each experience—whether challenging or rewarding—added tools to my quality engineering toolkit. 🧰 How have different roles influenced your testing approach?

Postman is to API testing what Excel is to data analysis. Many use only 10% of its capabilities, missing the transformation from tool to platform. When most people think of Postman, they picture a simple request sender. But in my experience, it's a comprehensive enterprise testing solution that transformed how we approach API quality. 🔄 By creating structured collections with environment variables, data-driven tests, and pre-request scripts, we built a framework that could validate 320 endpoints automatically. The tests became living documentation that new team members could understand at a glance. Integration with our CI/CD pipeline was the real game-changer. Every code change triggered relevant API tests, catching regressions before they reached human testers. Newman, Postman's command-line runner, made this seamless. The result? An 80% reduction in defect leakage for our APIs and comprehensive coverage that grew with our product. Sometimes the best tool isn't the newest or most complex—it's the one you already have, used to its full potential. 🚀 hashtag#Postman   hashtag#APITesting   hashtag#TestAutomation   hashtag#CI /CD  hashtag#Newman   hashtag#EnterpriseAPITesting

Go ahead, start testing that half-baked feature without a clear Definition of Ready. I'm sure you won't waste hours on clarifications, rework, and frustration. Of course, I'm being facetious. But I've seen countless QA cycles derailed because testing began before features were truly ready for validation. The cost in team morale and efficiency is enormous. 🚧 That's why I'm passionate about establishing a robust Definition of Ready (DoR) from a quality perspective. Our DoR checklist includes essentials like complete acceptance criteria, documented edge cases, test data availability, and environment readiness. The impact was immediate after implementation. Blockers during testing decreased by 70%, rework cycles were cut in half, and our defect escape rate plummeted. Most importantly, the relationship between development and QA transformed from adversarial to collaborative. By refusing to start testing before all DoR criteria were met, we actually accelerated delivery. Counter-intuitive perhaps, but true quality is about doing things right the first time. ✅ Does your team have a formal Definition of Ready?

The most valuable quality metrics are often the ones nobody wants to talk about. They reveal uncomfortable truths about your development process. After years of experimenting with dozens of quality metrics, I've narrowed down the four KPIs that actually move the needle for engineering teams. And they're probably not what you think. 📊 First, defect escape rate – the percentage of bugs found in production vs. testing. This single metric reveals more about your QA effectiveness than test counts ever could. It forces honest conversations about coverage gaps. Second, flakiness index – the percentage of tests that fail intermittently. High flakiness destroys trust in your automation and wastes valuable debugging time. Third, mean time to detect (MTTD) – how quickly issues are found after they're introduced. This measures your feedback loop efficiency far better than test execution time. Fourth, regression coverage index – how much of your critical functionality is protected by automated checks. Notice I didn't say code coverage, which can be gamed. 🎯 Which of these metrics does your team track? Are there others you find more valuable?

TagUI VS Playwright Comparing TagUI and Playwright for UI automation is like choosing between a Swiss Army knife and a surgical scalpel. Each has its place, but using the wrong one can be painful. When our team needed to automate complex UI workflows at scale, we conducted parallel POCs with TagUI (with Omni Parser) and Playwright with Python. The differences were immediately apparent. 🔄 TagUI excelled at quick automation of business processes with its natural language syntax, making it accessible to non-developers. Our business analysts could create tests without deep coding knowledge. However, it showed limitations with complex dynamic elements. Playwright, on the other hand, offered incredible precision and control. Its auto-waiting mechanisms and powerful selectors handled dynamic content elegantly, and its speed was noticeably better for large test suites. The tradeoff was a steeper learning curve. Our hybrid approach ultimately leveraged both: TagUI for business process validation and Playwright for complex UI testing. This combination reduced manual effort significantly while maintaining robust coverage across different testing needs. 🚀 Have you worked with either of these tools?

Designing Modular & Reusable QA Architectures Great test architecture is like a LEGO set—simple blocks that combine to build something complex, yet easy to reconfigure when needs change. Building scalable test architecture isn't about writing more tests—it's about writing the right tests that can grow with your product. After years of dealing with brittle, maintenance-heavy frameworks, I've learned this lesson well. 🧩 The key is modularity. By designing plug-and-play test modules for feature components, we separated the "what" from the "how." Our test data, execution logic, and validation steps became independent, reusable blocks. This approach paid dividends when we needed to onboard new endpoints.  Instead of starting from scratch, we could assemble existing components like building blocks, reducing implementation time by 60%. Reusability doesn't just save time—it ensures consistency. When every test follows the same patterns and best practices, our coverage becomes more predictable and easier to maintain. 📈 What's your approach to test architecture?

When diving into something new, questions are powerful—they clarify understanding and guide our next steps.  However, it's crucial to distinguish between questions aimed at gaining genuine clarity and those driven solely by a desire to avoid mistakes and achieve absolute certainty. Consider test automation: asking questions like, "How can I effectively use assertions to verify results?" brings clarity and enhances your skills. But continually asking, "How can I be absolutely sure my scripts will never fail in daily runs?" may lead to endless preparation, hesitation, and missed opportunities for real learning and innovation. Embracing uncertainty encourages experimentation, resilience, and growth. As philosopher Erich Fromm insightfully said: 🧩 “Creativity requires the courage to let go of certainties.” Echoing this wisdom, Francis Bacon reminds us: 🧩“If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties.” Let's strive for questions that clarify our path, not those that trap us in endless loops of doubt.
