Why testing is software necessary?

Testing is crucial in software development because it ensures that the software functions as intended and meets user expectations. By identifying and fixing bugs early, testing helps prevent costly issues and security vulnerabilities before the software is released. It also improves the overall quality and reliability of the product, leading to better user satisfaction. Testing allows developers to verify that each part of the software works correctly, from individual components to the entire system.

In essence, testing is an essential step in delivering a safe, effective, and high-quality software product.
