Parameterizing the Tests with Multiple Data using TestNG

The video tutorial explains how to parameterize data in test cases using TestNG's data provider annotation. It covers creating a data provider, implementing test cases with different data sets, and running these tests to achieve parameterization and data-driven testing. The tutorial also demonstrates how to handle multiple data sets and ensure the correct data types are used in tests.
