-
Foundation: Traditional Testing & Core Programming
4 weeksGoals
- Master software testing fundamentals (unit, integration, E2E).
- Achieve proficiency in Python for scripting and automation.
- Understand basic API testing and version control with Git.
Resources
- 'The Art of Software Testing' by Glenford Myers
- Official Python & Pytest documentation
- Postman Learning Center
- GitHub's interactive Git tutorial
MilestoneYou can independently design and automate tests for a standard REST API application using Python and Pytest.
-
Core: AI Fundamentals & LLM Testing Paradigms
8 weeksGoals
- Learn key ML/AI concepts (transformers, embeddings, fine-tuning).
- Gain hands-on experience with major LLM APIs (OpenAI, Anthropic).
- Study and implement different evaluation methods (static, model-as-judge, human-in-the-loop).
Resources
- Fast.ai practical deep learning course
- Hugging Face NLP course
- LangChain documentation and tutorials
- Papers on LLM evaluation (e.g., 'ChatGPT is not all you need')
MilestoneYou can build a simple RAG pipeline and write a comprehensive test suite for it using evaluation libraries like RAGAS, assessing faithfulness, relevance, and hallucination.
-
Advanced: Specialization & MLOps Integration
6 weeksGoals
- Deep dive into AI security testing and red-teaming techniques.
- Learn to build and scale evaluation datasets and synthetic data generators.
- Integrate quality gates for AI into CI/CD and monitoring platforms.
Resources
- OWASP AI Security & Privacy Guide
- Google's 'People + AI Guidebook'
- MLOps Zoomcamp (community course)
- Weights & Biases documentation
MilestoneYou can design an end-to-end AI quality assurance strategy for a production application, including automated regression testing, performance benchmarking, and bias monitoring dashboards.
Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
Build a RAG System and a Comprehensive Test Suite for It
IntermediateBuild a simple Retrieval-Augmented Generation chatbot over a small document set. Then, create a test suite that evaluates retrieval precision/recall, answer faithfulness, and relevance using libraries like RAGAS or DeepEval.
AI Red-Teaming Challenge
AdvancedTake a public LLM API (or a local model) and attempt to systematically break its safety guardrails using techniques like prompt injection, jailbreaking, and bias probing. Document your methods, success rates, and suggest mitigations.
Create a Model-as-a-Judge Evaluation Pipeline
IntermediateUse a powerful LLM (like GPT-4) to evaluate the outputs of a smaller, cheaper model. Build a pipeline that takes a prompt and two answers (from the weak model) and has the judge model score them on criteria like helpfulness and safety.
Automate Quality Monitoring for a Production LLM
AdvancedDesign a system that samples outputs from a (mock) production LLM endpoint. Automatically run them through a series of checks (PII leakage, toxicity, hallucination detection via a smaller model) and visualize the quality metrics on a dashboard (e.g., using Grafana or Streamlit).
