import org.testng.annotations.BeforeTest;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.AfterSuite;
public class NewTest {
  @Test(dataProvider = "dp")
  public void f(Integer n, String s) {
  }
  @BeforeMethod
  public void beforeMethod() {
  System.out.println("Before Method");
  }
  @AfterMethod
  public void afterMethod() {
	  System.out.println("After Method");

  @DataProvider
  public Object[][] dp() {
