About this course
Compose true agentic workflows for QA — plans, cases, scripts, and live API testing, all in Python.
What you'll learn
- LangChain + LangGraph end-to-end
- Agents that write plans, cases, scripts
- API testing in the loop
What you'll build
A LangGraph orchestration for a QA workflow
Agents that produce test plans, test cases and scripts
API testing executed inside the graph
Human-in-the-loop approval steps
Project architecture
The pipeline you assemble across the course:
- Requirement
- Planner node
- Test case generator node
- Script generator node
- API test execution
- Review / approval node

FAQ
LangChain or LangGraph?
Both — LangChain for the building blocks, LangGraph for the stateful orchestration around them.
Is this advanced?
It is the deep end of the agentic track. Start with the AutoGen course if agents are new to you.
