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.

What are the benefits of using a data provider for testing?

Describe the structure of the data array used in parameterization.

How can you differentiate between a restricted user and a non-restricted user in tests?

In what scenario would you need to create multiple rows in the data provider?

How does the test execution flow when using a data provider?

What is the significance of the return type in the data provider method?

What happens if the data types expected by the test do not match the data provided?
