Whether you're a seasoned developer or just starting out, implementing proper testing strategies can save you countless hours of debugging and improve the overall quality of your code.

Why Testing Matters

Testing isn't just about finding bugs; it's about building confidence in your code. When you have a comprehensive test suite, you can:

1. Make changes without fear of breaking existing functionality
2. Document how your code is supposed to work
3. Improve the design of your system
4. Reduce the cost of maintenance in the long run

Types of Testing

Unit Testing

Unit tests focus on individual components or functions in isolation. They verify that each piece of your code works correctly on its own.
