Outcomes
What you'll be able to do
- Apply spec-first methodology: define tests as specifications before any implementation
- Generate professional unit tests with Claude Code using pytest
- Build complete test pyramids: unit, integration, and E2E tests
- Execute the full TDD cycle (red-green-refactor) with Claude Code as implementer
- Achieve 90%+ coverage with AI-assisted edge case discovery
- Create mocking strategies, reusable fixtures, and automated validation loops
- Set up CI pipelines with GitHub Actions for automated testing
- Build a complete application 100% with TDD + Claude Code
Before you start
What you need to bring
It's for you if...
- Developers using Claude Code who want a systematic method to validate AI-generated code
- Teams adopting agentic development who need testing standards and quality gates
- Professionals who know testing but want to integrate AI into their TDD workflow
- Python developers who want to accelerate test writing without sacrificing quality
- Anyone building with AI tools who wants confidence that generated code actually works
Requirements and materials
- Completed guides #1-6 of the Claude Code Agentic Development Path (or equivalent Claude Code experience)
- Intermediate Python (functions, classes, modules, error handling)
- Basic pytest familiarity (helpful but not required — reinforced in Module 2)
- Git and GitHub basics (commits, push, pull requests)
- No prior TDD experience required (taught from scratch)

Common questions
What people usually ask
No limit. It's a free guide: come in whenever you like, as often as you like.
No. Modules run from easier to harder, but you can jump to the one you need. Progress is saved per lesson.
Whatever is needed is listed under “What you need to bring”, above. If nothing is listed there, you can start from zero.
In the WhatsApp group, and every two weeks there's a live with an instructor where questions get worked through.
