Re-explain

TDD is a software development methodology where tests are written before the actual code. The core principles are:

  • Test First: Write a failing test before writing any production code
  • Minimal Code: Write only enough code to make the test pass
  • Incremental Development: Build functionality in small, testable increments
  • Continuous Refactoring: Improve code structure while maintaining functionality
    TDD follows the Red-Green-Refactor cycle, ensuring code is thoroughly tested and well-designed from the start.
