Testing methods are systematic approaches used to evaluate the performance, quality, or functionality of a product or system. Common methods include unit testing, which checks individual components, and integration testing, which assesses how different parts work together. These methods help identify issues early in the development process. Another important testing method is user acceptance testing (UAT), where real users test the product to ensure it meets their needs. Additionally, automated testing uses software tools to run tests quickly and efficiently, while manual testing involves human testers executing test cases. Each method serves a specific purpose in the overall testing strategy.
