A Practical Introduction to Test-Driven Development Syllabus

Overview: This 8-week course provides a practical, hands-on introduction to Test-Driven Development (TDD), designed for intermediate developers seeking to improve code quality and software design. Through structured modules, learners will master the red-green-refactor cycle, write effective unit tests, and apply TDD principles in realistic development scenarios. Expect a time commitment of approximately 4–6 hours per week, combining video lectures, coding exercises, and quizzes to reinforce learning. The course concludes with a final project integrating TDD into a small application, solidifying skills for real-world use.

Module 1: Introduction to Test-Driven Development

Estimated time: 6 hours

• What is TDD and why it matters
• Comparing TDD with traditional development
• Benefits of improved code quality and reduced bugs
• Setting up your testing environment

Module 2: The Red-Green-Refactor Cycle

Estimated time: 6 hours

• Writing failing tests (red phase)
• Implementing minimal code to pass (green phase)
• Refactoring for clean design and readability
• Iterating through the TDD cycle effectively

Module 3: Unit Testing and Assertions

Estimated time: 6 hours

• Creating reliable unit tests
• Using assertion methods effectively
• Testing edge cases and error handling
• Ensuring test independence and repeatability

Module 4: Applying TDD in Real Projects

Estimated time: 6 hours

• Integrating TDD into agile workflows
• Working with testing frameworks and mocking
• Best practices for team adoption

Module 5: Improving Code Maintainability with TDD

Estimated time: 4 hours

• Using TDD to reduce technical debt
• Enhancing software design through iterative testing
• Writing maintainable and testable code

Module 6: Final Project

Estimated time: 8 hours

• Design and implement a small application using TDD
• Apply red-green-refactor workflow across multiple features
• Submit code with passing tests and refactored design

Prerequisites

• Familiarity with a programming language (e.g., Python, JavaScript, or Java)
• Basic understanding of software development concepts
• Experience writing and debugging code

What You'll Be Able to Do After

• Understand the core principles and benefits of test-driven development
• Write effective unit tests before implementing functional code
• Apply the red-green-refactor workflow in practice
• Improve software design through iterative testing and development
• Use TDD to increase code maintainability and reduce technical debt
