I am using eclipse with testng plugin.

I am having a problem that i am not able to understand that when i run the test, sometimes i get 3 threads executing in parallel while sometimes only 1 thread (i.e. it becomes sequential).

Anything i might be missing here?

my testng.xml :

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" > <suite name="Suite" parallel="methods" thread-count="3"> <test name="TestNG"> <classes> <class name="com.example.testng.TestNG" /> </classes> </test>  </suite> 

My TestNG.java :

package com.example.testng;

import org.testng.annotations.Test;

public class TestNG {
  @Test
  public void test1() {
	  System.out.println("Start of test 1");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 1");
	  }
  }
  
  @Test
  public void test2() {
	  System.out.println("Start of test 2");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 2");
	  }
  }
  
  @Test
  public void test3() {
	  System.out.println("Start of test 3");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 3");
	  }
  }
  
  @Test
  public void test4() {
	  System.out.println("Start of test 4");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 4");
	  }
  }
  
  @Test
  public void test5() {
	  System.out.println("Start of test 5");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 5");
	  }
  }
  
  @Test
  public void test6() {
	  System.out.println("Start of test 6");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 6");
	  }
  }
  
  @Test
  public void test7() {
	  System.out.println("Start of test 7");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 7");
	  }
  }
  
  @Test
  public void test8() {
	  System.out.println("Start of test 8");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 8");
	  }
  }
  
  @Test
  public void test9() {
	  System.out.println("Start of test 9");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 9");
	  }
  }
  
  @Test
  public void test10() {
	  System.out.println("Start of test 10");
	  try {
		  Thread.sleep(10000);
	  } catch (InterruptedException e) {
		  // TODO Auto-generated catch block
		  e.printStackTrace();
	  } finally {
		  System.out.println("End of test 10");
	  }
  }
}

I didnt quite understand what is your question here.

>>>>I am having a problem that i am not able to understand that when i run the test, sometimes i get 3 threads executing in parallel while sometimes only 1 thread (i.e. it becomes sequential).

How are you stating this ? Have you tried adding a System.out.println("Thread ID: " + Thread.currentThread.getId()) and see what you get ? This is the only reliable way of figuring out if you are indeed spinning off threads in parallel or sequence.

Thanks & Regards

Hey Krishnan, thanks for the fast reply and sorry for my late one.

I figured it out just a few minutes ago. I was accidently running the TestNG.java file sometimes which resulted in the sequential execution of the tests and when unknowingly ran testng.xml the tests ran parallely since i had configured their parallel run in testng.xml file.

Silly mistake ;P on my part.
