Test the AI features
your product just grew

Your test suite goes green and the answer is still wrong. This course is about the gap between those two facts — hallucination detection, prompt injection, RAG retrieval quality, agent tool calls — taught against three real applications you attack from the browser, not slides about them.

There is a Python & DSA track too, twenty-four modules from variables to dynamic programming, with every code sample running in the page.

What you'll learn, and what you'll break

Three things sit behind the login. Each one has a part you can open free, so you can judge the teaching before you judge the price.

Course

GenAI application testing

For testers whose product has grown an AI feature. LLM output evaluation, hallucination detection, prompt injection and red-team testing, RAG retrieval quality and knowledge-base poisoning, AI agents and MCP tool calls, and automation with Promptfoo, DeepEval and RAGAS. Sixteen modules, three certification levels. Module 1 is free.

Course

Python Zero to Hero, with DSA

Twenty-four modules in six phases, from variables to dynamic programming, five lessons each. Every code sample has a Run button and executes in your browser — there is no Python to install and nothing to configure before your first line runs. Phases 3 to 5 are the interview material. All of Phase 1 is free.

Hands-on

Three capstones to attack

A RAG system in five deliberately broken versions, a multi-agent booking system, and a capital-markets capstone answering the same derivatives questions three ways. All run in the cloud and open in your browser — ask them questions, run the red-team and blue-team suites case by case, add your own documents, inspect the chunks and Hit@k in the vector database, and read the trace in the logs. Nothing to install.

How it works

Learn

Lessons, slide decks, documents and spreadsheets in one place, on any device. Python lessons run their own code in the page.

Practise

Three real applications are hosted for you — a RAG system in five deliberately broken versions, a multi-agent booking system, and a capital-markets capstone. You test them, not a slide about them.

Certify

Pass an exam and earn a certificate carrying a unique number that anyone can check without an account. Nothing is awarded for finishing videos.

Common questions

Whether you need Python first, how this compares with ISTQB CT-AI, how to test a RAG system, and what an AI testing career actually looks like coming from manual testing — all answered on the FAQ page.
