REST API Automation Testing from Scratch - REST Assured Java - Understanding TestNG Data Provider for Parameterization

The video tutorial introduces the TestNG data provider annotation, explaining its role in parameterizing test cases. It covers the creation of multidimensional arrays in Java, which are used to store data sets for tests. The tutorial demonstrates how to link a data provider to test cases, allowing tests to run multiple times with different data sets. It also explains how to implement arrays for parameterization and how to return and connect data providers to tests.
