Detailed Description

Listener for test progress and result.

Implementing the Observer pattern a TestListener may be registered to a TestResult to obtain information on the testing progress. Use specialized sub classes of TestListener for text output (TextTestProgressListener). Do not use the Listener for the test result output, use a subclass of Outputter instead.

The test framework distinguishes between failures and errors. A failure is anticipated and checked for with assertions. Errors are unanticipated problems signified by exceptions that are not generated by the framework.

Here is an example to track test time:

 #include <cppunit/TestListener.h>
 #include <cppunit/Test.h>
 #include <time.h>    // for clock()

 class TimingListener : public CppUnit::TestListener
 {
 public:
   void startTest( CppUnit::Test *test )
   {
     _chronometer.start();
   }
  
   void endTest( CppUnit::Test *test )
   {
     _chronometer.end();
     addTest( test, _chronometer.elapsedTime() );
   }

   // ... (interface to add/read test timing result)

 private:
   Clock _chronometer;
 };

And another example that track failure/success at test suite level and captures the TestPath of each suite:

 class SuiteTracker : public CppUnit::TestListener
 {
 public:
   void startSuite( CppUnit::Test *suite )
   {
     m_currentPath.add( suite );
   }
   
   void addFailure( const TestFailure &failure )
   {
     m_suiteFailure.top() = false;
   }
 
   void endSuite( CppUnit::Test *suite )
   {
     m_suiteStatus.insert( std::make_pair( suite, m_suiteFailure.top() ) );
     m_suitePaths.insert( std::make_pair( suite, m_currentPath ) );

     m_currentPath.up();
     m_suiteFailure.pop();
   }

 private:
   std::stack<bool> m_suiteFailure;
   CppUnit::TestPath m_currentPath;
   std::map<CppUnit::Test *, bool> m_suiteStatus;
   std::map<CppUnit::Test *, CppUnit::TestPath> m_suitePaths;
 };

Member Function Documentation

virtual void TestListener::addFailure (  const TestFailure &  failure  )  [inline, virtual]

Called when a failure occurs while running a test. See also: TestFailure. Warning: failure is a temporary object that is destroyed after the method call. Use TestFailure::clone() to create a duplicate. Reimplemented in BriefTestProgressListener, TestResultCollector, TestSuccessListener, TextTestProgressListener, and TextTestResult.

virtual void TestListener::endSuite (  Test *  suite  )  [inline, virtual]

Called by a TestComposite after running its child tests.

virtual void TestListener::endTest (  Test *  test  )  [inline, virtual]

Called just after a TestCase was run (even if a failure occured). Reimplemented in BriefTestProgressListener.

virtual void TestListener::endTestRun (  Test *  test, TestResult *  eventManager )  [inline, virtual]

Called by a TestRunner after running the test. TextTestProgressListener use this to emit a line break. You can also use this to do some global uninitialisation. Parameters: test  Test that was run. eventManager  Event manager used for the test run. Reimplemented in TextTestProgressListener.

virtual void TestListener::startSuite (  Test *  suite  )  [inline, virtual]

Called by a TestComposite just before running its child tests.

virtual void TestListener::startTest (  Test *  test  )  [inline, virtual]

Called when just before a TestCase is run. Reimplemented in BriefTestProgressListener, TestResultCollector, TextTestProgressListener, and TextTestResult.

virtual void TestListener::startTestRun (  Test *  test, TestResult *  eventManager )  [inline, virtual]

Called by a TestRunner before running the test. You can use this to do some global initialisation. A listener could also use to output a 'prolog' to the test run. Parameters: test  Test that is going to be run. eventManager  Event manager used for the test run.
