Question
Explain the goals of the following testing strategies (4 Marks)i. Validation testingii. Defect testing
Solution
i. Validation Testing: The primary goal of validation testing is to ensure that the software meets the specified requirements and is able to function in its intended environment. This type of testing is typically conducted at the end of the development process and is used to verify that the software is ready for release. It checks for functionality, usability, and reliability of the software.
ii. Defect Testing: The main objective of defect testing is to identify and fix any errors or bugs in the software. This type of testing is usually conducted during the development process and is used to ensure that the software is functioning as expected. It involves running the software under controlled conditions and checking for any unexpected behavior or results. The goal is to find and fix any issues before the software is released to the end users.
