After the execution of the test in terms of finding the defect that has been already detected and fixed, re-execution of the same test with different input values to confirm the original defect has been successfully removed is called Re-testing or confirmation Testing.
Retesting is also called Data-Driven Testing, but the difference between both is, Retesting is a manual testing process whereas application testing done with the entire new set of data.
Data-Driven Testing(DDT) : It is an Automation testing process where an application will be tested with multiple test data.It is simple and easy than retesting where tester just sits in front of the system and enter different new input values manually from front-end interface, it is really a boring technique.
