    public class Test1 {
        @BeforeClass
        public void test1() {

            System.out.println("printing Before Class Method");
        }
        @Test (priority = 1)
    public void test2() {

            System.out.println("printing test_2");
        }

        @Test (priority = 3)
    public void test3() {

            System.out.println("printing test_3");
