Software quality refers to the degree to which a software product meets specified requirements and user expectations. It encompasses various attributes, including functionality, reliability, usability, efficiency, maintainability, and portability. High-quality software performs well under expected conditions and is free from critical defects, ensuring a positive user experience. To assess software quality, developers often use testing methods such as unit testing, integration testing, and user acceptance testing. These processes help identify and fix issues before the software is released. Additionally, adhering to quality standards, like ISO 25010, can guide teams in delivering reliable and effective software solutions.
