Obtain an iterator over the collection of test case classes loaded by loadTestCases.

 public  void loadTestCases(Iterator classNamesIterator) 
{
                               
        while (classNamesIterator.hasNext())

            try
            {
                Class candidateClass = Class.forName(className);
                addClassIfTestCase(candidateClass);
            }
            catch (ClassNotFoundException e)
            {
                System.err.println("Cannot load class: " + className + " " + e.getMessage());
            }
            catch (NoClassDefFoundError e)
            {
                System.err.println("Cannot load class that " + className + " is dependant on");
            }
        }
}

Load the classes that represent test cases we are interested.
