Order of execution of tests in TestNG

Question

How to customize the order of execution of tests in TestNG?

For example:

public class Test1 {
  @Test
  public void test1() {
      System.out.printl         


        

Answer 1

I've faced the same issue, the possible reason is due to parallel execution of testng and the solution is to add Priority option or simply update preserve-order="true" in your testng.xml.
