TDD course logo – Test-Driven Development workshop

Overview

Test-Driven Development (TDD) is a disciplined loop: write a failing test, make it pass, then refactor. It builds quality in, accelerates delivery, and makes change safe. Teams gain a living safety net and a shared design language.

Without TDD, the development speed is not steady, codebases become brittle, defects surface late, and releases slow down. With TDD, you enable frequent integration, confident refactoring, and architecture that remains adaptable under pressure.

What You Will Learn

  • Work the Red–Green–Refactor cycle end-to-end with clarity
  • Write expressive, trustworthy unit tests that support change
  • Use seams, fakes, and mocks without over-coupling
  • Refactor safely to improve readability and design
  • Introduce TDD into legacy codebases
  • Connect TDD to CI/CD, trunk-based flow, and Agile practices
  • Make TDD a sustainable team habit

Why TDD Matters

With TDD Without TDD
Steady flow: small daily investments keep development predictable Uneven flow: short bursts followed by slowdowns from growing debt.
Clean, evolvable design via refactoring Hard-to-change code, rising debt
Confident, frequent releases Risky changes, long cycles
Clear seams, better decoupling Tight coupling, fragile tests
Shared quality language across the team Quality subjective and inconsistent

Course Topics

Code Smells & Testability

Recognize code smells, create seams, and design for testability.

TDD Cycle

Master the Red–Green–Refactor loop, cadence, and common pitfalls.

Red–Green–Refactor in Practice

Driving design with tests and refactoring safely at every step.

Mocking & Fakes

Collaborator isolation without over-mocking or fragile tests.

Working with Legacy Code

Use characterization tests, safe refactoring, and strangler patterns.

Agile Teams with TDD

Pairing, ensemble testing, CI/CD, and trunk-based workflows.

TDD with AI

Explore how AI-assisted tools can suggest tests, detect code smells faster, and guide refactoring while keeping TDD discipline at the center.

Course Objectives

  • Deliver features at a steady pace using TDD
  • Design small, cohesive units that are easy to test and evolve
  • Refactor confidently to reduce technical debt
  • Apply mocking/faking patterns without fragile tests
  • Break into legacy code with characterization tests
  • Align TDD with your Definition of Done and CI/CD
  • Establish team agreements that make TDD stick
