Describe the principles of Test-Driven Development (TDD) and its benefits.
Hey Mark
Test-Driven Development (TDD) is a methodology that involves writing tests before implementing the actual code, promoting better code quality, improved design, and easier maintenance. Its principles include:
- Write a failing test: Start with a test for the desired function.
- Implement code: Create code to pass the test.
- Refactor: Optimize the code while ensuring tests still pass.
Benefits:
- Improved Code Quality: Encourages simpler and cleaner code.
- Confidence in Refactoring: Safeguard against regressions.
- Clearer Requirements: Tests act as documentation, clarifying intended behaviors.
