Testing methods are systematic approaches used to evaluate the performance, quality, and reliability of products or systems. Common methods include unit testing, where individual components are tested for functionality, and integration testing, which assesses how different components work together. These methods help identify defects early in the development process. Another important testing method is user acceptance testing (UAT), where real users test the system to ensure it meets their needs. Additionally, automated testing uses software tools to execute tests automatically, increasing efficiency and consistency. Each method plays a crucial role in delivering high-quality products.
