public static class JUnitExtensions.MultiThreadedTestCase

extends junit.framework.TestCase

A multi-threaded JUnit test case. To perform test cases that spin off threads to do tests:

• Extend MultiThreadedTestCase
• Write your tests cases as normal except for when you want to spin off threads.
• When you want to spin off threads:
  • Instead of implementing Runnable extend MultiThreadedTestCase.TestCaseRunnable.
  • Define runTestCase () to do your test, you may call fail (), assert () etc. and throw exceptions with impunity.
  • Handle thread interrupts by finishing.
• Instantiate all the runnables (one for each thread you wish to spawn) and pass an array of them to runTestCaseRunnables ().

That's it. An example is below:

 public class MTTest extends JUnitExtensions.MultiThreadedTestCase
 {
   MTTest (String s) { super (s); }
   public class CounterThread extends JUnitExtensions.TestCaseRunnable
   {
     public void runTestCase () throws Throwable
     {
       for (int i = 0; i < 1000; i++)
       {
         System.out.println ("Counter Thread: " + Thread.currentThread () + " : " + i);
         // Do some testing...
         if (Thread.currentThread ().isInterrupted ()) {
           return;
         }
       }
     }
   }

   public void test1 ()
   {
     TestCaseRunnable tct [] = new TestCaseRunnable [5];
     for (int i = 0; i < 5; i++)
     {
       tct[i] = new CounterThread ();
      }
     runTestCaseRunnables (tct);
   }
 }
