本文展示了一个使用CppUnit进行单元测试的简单示例。该示例定义了一个名为Test的测试类，其中包含一个名为testHelloWorld的测试用例，用于输出经典问候语。此外，文章还介绍了如何设置测试运行器并执行测试。

//--- Hello, World! for CppUnit

#include <iostream>

#include <cppunit/TestRunner.h>
#include <cppunit/TestResult.h>
#include <cppunit/TestResultCollector.h>
#include <cppunit/extensions/HelperMacros.h>
#include <cppunit/BriefTestProgressListener.h>
#include <cppunit/extensions/TestFactoryRegistry.h>

class Test : public CPPUNIT_NS::TestCase
{
  CPPUNIT_TEST_SUITE(Test);
  CPPUNIT_TEST(testHelloWorld);
  CPPUNIT_TEST_SUITE_END();

public:
  void setUp(void) {}
  void tearDown(void) {} 

protected:
  void testHelloWorld(void) { std::cout << "Hello, world!" << std::endl; }
};

CPPUNIT_TEST_SUITE_REGISTRATION(Test);

int main( int ac, char **av )
{
  //--- Create the event manager and test controller
  CPPUNIT_NS::TestResult controller;

  //--- Add a listener that colllects test result
  CPPUNIT_NS::TestResultCollector result;
  controller.addListener( &result );        

  //--- Add a listener that print dots as test run.
  CPPUNIT_NS::BriefTestProgressListener progress;
  controller.addListener( &progress );      

  //--- Add the top suite to the test runner
  CPPUNIT_NS::TestRunner runner;
  runner.addTest( CPPUNIT_NS::TestFactoryRegistry::getRegistry().makeTest() );
  runner.run( controller );

  return result.wasSuccessful() ? 0 : 1;
}
