## 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;
};
ExceptionTestCaseDecorator
Expected exception test case decorator.
Definition ExceptionTestCaseDecorator.h:45
CPPUNIT_ASSERT_EQUAL
#define CPPUNIT_ASSERT_EQUAL(expected, actual)
Asserts that two values are equals.
Definition TestAssert.h:332

## Member Typedef Documentation

## ◆ ExpectedExceptionType

template<class ExpectedException >

typedef ExpectedException ExceptionTestCaseDecorator< ExpectedException >::ExpectedExceptionType

## Constructor & Destructor Documentation

## ◆ ExceptionTestCaseDecorator()

template<class ExpectedException >

ExceptionTestCaseDecorator< ExpectedException >::ExceptionTestCaseDecorator | ( | TestCase * | test | ) |
| inline

Decorates the specified test.

Parameters

  test | TestCase to decorate. Assumes ownership of the test.

## Member Function Documentation

## ◆ checkException()

template<class ExpectedException >

virtual void ExceptionTestCaseDecorator< ExpectedException >::checkException | ( | ExpectedExceptionType & |  | ) |
| inlineprivatevirtual

Called when the exception is caught.

Should be overriden to check the exception.

## ◆ runTest()

template<class ExpectedException >

void ExceptionTestCaseDecorator< ExpectedException >::runTest | ( |  | ) |
| inlinevirtual

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.

Reimplemented from TestCase.

The documentation for this class was generated from the following file:
