What's the difference between TDD and traditional testing approaches?

beginner

Re-explain

Traditional Testing:

Code first, test later
Tests verify existing functionality
Often achieves lower test coverage
Testing is seen as a separate phase
TDD:
Test first, code second
Tests drive the design and implementation
Achieves high test coverage naturally
Testing is integrated into development
TDD treats tests as specifications and design tools, while traditional testing treats them as validation tools.
