Detailed Description

template<class ExpectedException>
class ExceptionTestCaseDecorator< ExpectedException >

Expected exception test case decorator.

A decorator used to assert that a specific test case should throw an exception of a given type.

You should use this class only if you need to check the exception object state (that a specific cause is set for example). If you don't need to do that, you might consider using CPPUNIT_TEST_EXCEPTION() instead.

Intended use is to subclass and override checkException(). Example:

 class NetworkErrorTestCaseDecorator : 
           public ExceptionTestCaseDecorator<NetworkError>
 {
 public:
   NetworkErrorTestCaseDecorator( NetworkError::Cause expectedCause )
       : m_expectedCause( expectedCause )
   {
   }
 private:
   void checkException( ExpectedExceptionType &e )
   {
     CPPUNIT_ASSERT_EQUAL( m_expectedCause, e.getCause() );
   }

   NetworkError::Cause m_expectedCause;
 };

Member Function Documentation

template<class ExpectedException>
virtual void ExceptionTestCaseDecorator< ExpectedException >::checkException (  ExpectedExceptionType &  e  )  [inline, private, virtual]
 

Called when the exception is caught.

Should be overriden to check the exception.

template<class ExpectedException>
void ExceptionTestCaseDecorator< ExpectedException >::runTest (   )  [inline, virtual]
 

Checks that the expected exception is thrown by the decorated test. is thrown.

Calls the decorated test runTest() and checks that an exception of type ExpectedException is thrown. Call checkException() passing the exception that was caught so that some assertions can be made if needed.
