Define the software testing?

Software testing is a process of evaluating a software application or system to identify any defects, errors, or bugs in order to ensure its quality and functionality. It involves executing the software with the intention of finding errors, verifying that it meets the specified requirements, and ensuring that it performs as expected. The goal of software testing is to uncover any issues that may affect the software's performance, reliability, security, and user experience, and to ensure that it meets the desired quality standards before it is released to end-users.
