Abstract:
Test-Driven Development (TDD) is a powerful software development methodology that emphasizes the use of automated tests to drive the design and implementation of code. One of the key concepts in TDD is the red-green-refactor cycle, which consists of writing a failing test, then writing the code to make the test pass, and finally refactoring the code to improve its quality. This cycle helps developers to write well-tested and maintainable code.

This talk aims to explore the best practices and real-world applications of the red-green-refactor cycle in TDD. The talk will cover the following topics:
- The principles and benefits of TDD
- The red-green-refactor cycle in detail
- Techniques for writing effective test cases and assertions
- Strategies for test-first and test-last development
- Mocking and stubbing dependencies in tests
- Test-driving legacy code and refactoring
- TDD best practices and anti-patterns

The talk will also include real-world examples and case studies to illustrate the benefits and challenges of using the red-green-refactor cycle in practice. The target audience for this talk is software developers, testers, and managers who are interested in learning about TDD and its applications in modern software development.
