name: Test-Driven Development
description: A software development approach where tests are written before the actual code, following a red-green-refactor
  cycle to ensure code quality and maintainability. TDD requires developers to write failing tests first, then write minimal
  code to make them pass, then refactor. It supports the full software development lifecycle from design through deployment
  and maintenance and is foundational to agile and extreme programming methodologies.
