Software testing is the process of evaluating a software application to ensure it meets specified requirements and functions correctly. This involves executing the software under various conditions to identify any bugs or issues that may affect its performance. Testing can be manual or automated, depending on the complexity and needs of the project. The main goal of software testing is to improve the quality of the software product before it is released to users. By identifying and fixing problems early, developers can enhance user satisfaction and reduce the risk of failures in real-world use.
