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
