A Software Tester is a professional responsible for evaluating software applications to ensure they function correctly and meet specified requirements. They identify bugs or issues in the software and report them to the development team for resolution. Their work helps improve the quality and reliability of software products before they are released to users. Software Testers use various testing methods, including manual testing and automated testing, to assess different aspects of the software, such as performance, usability, and security. They often collaborate with developers and project managers to ensure that the final product is user-friendly and free of critical errors.
