What if we want the same data provider to work differently for different methods like in a case where we test different data sets for different test methods, we will use method parameters in TestNG. We would like to run some of our tests each against a set of data values, verifying that the same conditions hold true for each. We have to pass the parameters to the test classes via a XML file. Let us create a class for the DataProvider method with all the Test Data as shown below: An extra parameter parallel is required to initiate parallel execution in TestNG using the data provider. Note that If we want to put the data provider in a different class, it needs to be a static method or a class with a non-arg constructor. Using @DataProvider and @Test in Separate Classes, TestNG Run Tests and Suites using Maven. Passing multiple parameters is just similar to the single parameters, but we will be providing multiple values in a single parameter.
