Test-Harness Enhancements

I added some simple load testing capability to Josh's Test Harness
You have to apply the following test-harness.diff patch
- To apply the patch do:
  - cd sakai-2-1-x/test-harness/src/java
  - patch -p0 < test-harness.diff
Examples:
- public void testGetCoursesByTerm() throws Exception { // Unit test List courseList = null; courseList = courseManagementManager.getCoursesByTerm("2006","01"); Assert.assertNotNull(courseList); // Load Test SakaiTestMethodInvoker testMethodInvoker = new SakaiTestMethodInvoker(); testMethodInvoker.runOnce(courseManagementManager, "getCoursesByTerm", new Object[] {"2006","01"}, new Class[] {String.class, String.class}); testMethodInvoker.runMultipleTimes(courseManagementManager, "getCoursesByTerm", new Object[] {"2006","01"}, new Class[] {String.class, String.class}, 10); testMethodInvoker.runThreadedOnce(courseManagementManager, "getCoursesByTerm", new Object[] {"2006","01"}, new Class[] {String.class, String.class}, 5); testMethodInvoker.runThreadedMultipleTimes(courseManagementManager, "getCoursesByTerm", new Object[] {"2006","01"}, new Class[] {String.class, String.class}, 10, 5); }
