The output of running above code as test suite is : As you can see from the previous test results, TestNG has passed the optional value to the test method during the first test execution. As you can see in the code above, we utilized DataProvider in TestNG to aggregate multiple values into a single parameter rather than assigning values one at a time. We must also note that a DataProvider in TestNG returns a 2-D array, unlike other TestNG parameters. We can leverage these TestNG parameters to make the best of existing Selenium test automation scripts or create new scripts. It also helps in equipping complicated parameters to the test methods.
