how to parameterized test in TestNG using @dataprovider annotation ?

mapping of complex parameter types to a test method with  @DataProvider annotation

See example:

 public class ParameterizedLoginTest {

@Test(dataProvider = "parameterIntTestProvider")
 public void parameterIntTest(String UserName, String Password) {
 System.out.println("UserName " + UserName);
 System.out.println("Password " + Password);

 //This function will provide the parameter data
 // Selenium framework - read the data from xls file and put it in Object array
 // rows - number of time test has to be repeated
 // cols - number of parameters in test data
 @DataProvider(name = "Data-Provider-Function")
 public Object[][] parameterIntTestProvider() {

 Object[][] data = new Object[3][2];

 data[0][0] = "UserName1";
 data[0][1] = "UserName1@123";

 data[1][0] = "UserName2";
 data[1][1] = "UserName2@123";

 data[2][0] = "UserName2";
 data[2][1] = "UserName2@123";

 return data;

Run this and Checkout TestNG result pane

Now Add new tag in testng.xml

<test name="test3">
 <class name="testWordpress.ParameterizedLoginTest" ></class>


And run TestNG.xml and see testng HTML report
