Description: Test design is the process of defining the test cases and test scripts that will be executed to validate the functionality of software. This process is fundamental in the software development life cycle, as it ensures that applications meet specified requirements and function correctly in different scenarios. In the context of software development, test design integrates with tools that allow for the management and automation of tests, facilitating collaboration between development and testing teams. Test cases are created based on system requirements and can include functional, performance, security, and other types of testing. An effective test design not only identifies what needs to be tested but also establishes how the testing will be conducted, what data will be needed, and what criteria will be used to determine if the test has been successful. This helps minimize errors and improve the quality of the delivered software. Additionally, test design is an iterative process that can adapt as new features are developed or issues are identified, allowing for continuous improvement in the quality of the final product.
