You only test well what you know how to build.

Developer, then Test Manager, QA coach and technical lead: over 15 years, I have managed software quality in defense, e-commerce, insurance, energy, web services and telecoms. I founded STRATEST in 2018 to do this work with teams — not in their place.

My view of quality

Quality is not an opinion you give at the end. It is a property you build, and one you can measure. When a team cannot say where it stands, it is almost never a tooling problem: it is because no explicit decision has been made about what it is protecting.

I wrote code before I wrote tests. That changes how I work with development teams: I am not there to tell them their product is bad, I am there to make what is fragile visible — and fixable.

I am wary of test suites that keep growing. A suite of three thousand tests whose results nobody reads protects less than two hundred tests the team trusts. The right indicator is not the number of cases executed, it is the question: what would happen if this test failed? If the answer is “we rerun it,” the test is useless.

That is also why I teach. A consultancy that automates in place of its clients creates dependency. Passing on the skills is slower, and it is the only thing that lasts.

AI & LLM · hands-on since January 2025

AI, practiced before being recommended.

I do not recommend a tool I have not run myself. What AI really changes for QA — and what it does not change yet — is measured by building.

AI for QA, our take
Agents
Agentic applications with LangChain: tool calling, agent orchestration, several specialties per model.
Models
Claude, ChatGPT, Gemini, DeepSeek, GLM — and open models from Hugging Face, from 300 million to 32 billion parameters, quantized or not.
Techniques
RAG (embeddings, vector search), LoRA fine-tuning, zero-shot and few-shot, system prompt engineering.
Tooling
Python, PyTorch, Unsloth, Google Colab, Claude Code, Codex; on-demand GPU compute (Hyperstack, Vast.ai).
Business use
AI-driven process automation and integration of AI into business processes.
