1By adding @TestMethodOrder annotation
2on top of class and 
3than @Order tag on each test
4with giving them number 
5
6// these are all available option for ordering your tests
7//@TestMethodOrder(OrderAnnotation.class)
8//@TestMethodOrder(Random.class)
9//@TestMethodOrder(MethodName.class) // default options
10
11For Example :
12
13@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
14public class TestOrderingInJunit5 {
15
16    @Order(3)
17    @DisplayName("3. Test A method")
18    @Test
19    public void testA(){
20        System.out.println("running test A");
21    }
22    @Order(1)
23    @DisplayName("1. Test C method")
24    @Test
25    public void testC(){
26        System.out.println("running test C");
27    }
28    @Order(4)
29    @DisplayName("4. Test D method")
30    @Test
31    public void testD(){
32        System.out.println("running test D");
33    }
34    @Order(2)
35    @DisplayName("2. Test B method")
36    @Test
37    public void testB(){
38        System.out.println("running test B");
39    }
40    
41    
42    In this case it will print 
43    1. Test C
44    2. Test B
45    3. Test A
46    4. Test D
