Testing processes are systematic methods used to evaluate the functionality and performance of a product, often in software development. These processes help identify defects or issues before the product is released to users. Common types of testing include unit testing, integration testing, and user acceptance testing, each focusing on different aspects of the product. The testing process typically involves planning, designing test cases, executing tests, and reporting results. It ensures that the product meets specified requirements and works as intended. Effective testing processes contribute to higher quality products and improved user satisfaction, ultimately reducing costs associated with post-release fixes.
