Testing in software development is the process of verifying that your code works as expected. It's like proofreading an essay or double-checking a math problem to ensure everything is correct. Testing helps you find bugs (errors in the code) before your users do, making your applications more reliable and easier to maintain.
- Catch Bugs Early: Testing helps you identify and fix issues early in the development process, which is usually easier and less costly than fixing them later.
- Documentation: Tests can serve as documentation for your code, showing how it is supposed to work.
- Confidence in Changes: When you modify your code, tests ensure that everything still works as expected.
- Better Code Quality: Writing tests often forces you to write cleaner, more modular code, which is easier to understand and maintain.
