Answer Posted / lakshmanaraj bg
Regression Testing:
The objective of regression testing is to ensure software remains intact.
A baseline set of data and scripts will be maintained and executed to verify changes introduced during the release have not “undone” any previous code.
Expected results from the baseline are compared to results of the software being regression tested.
All discrepancies will be highlighted and accounted for, before testing proceeds to the next level.
Validation:
Validation checks that the product design satisfies or fits the intended usage (high-level checking) – i.e., you built the right product.
This is done through dynamic testing and other forms of review.
The process of evaluating software during or at the end of the development process to determine whether it satisfies specified requirements.
