/*! \brief Protects one or more test case run.
*
* Protector are used to globably 'decorate' a test case. The most common
* usage of Protector is to catch exception that do not subclass std::exception,
* such as MFC CException class or Rogue Wave RWXMsg class, and capture the
* message associated to the exception. In fact, CppUnit capture message from
* Exception and std::exception using a Protector.
*
* Protector are chained. When you add a Protector using
* TestResult::pushProtector(), your protector is in fact passed as a Functor
* to the first protector of the chain.
*
* TestCase protects call to setUp(), runTest() and tearDown() by calling
* TestResult::protect().
*
* Because the protector chain is handled by TestResult, a protector can be
* active for a single test, or a complete test run.
*
* Here are some possible usages:
* - run all test case in a separate thread and assumes the test failed if it
* did not finish in a given time (infinite loop work around)
* - performance tracing : time only the runTest() time.
* \sa TestResult, TestCase, TestListener.
