Software Testing is the process of evaluating and verifying that a software application works correctly, meets requirements, and is free of defects. It plays a critical role in the software development lifecycle by ensuring the quality, reliability, and performance of a product before it is released to users.Software testing involves executing programs, identifying bugs or errors, and ensuring that all features function as expected. Testers use various methods such as manual testing and automated testing to validate different aspects of the application, including functionality, usability, security, and performance.Common types of testing include unit testing, integration testing, system testing, and user acceptance testing (UAT). Testers may also use specialized tools and frameworks to automate repetitive tasks and improve efficiency.Overall, Software Testing helps deliver high-quality software by reducing risks, improving user satisfaction, and ensuring that applications perform reliably in real-world conditions
