#define TEUCHOS_TEST_THROW (   code,
  ExceptType,
  out,
  success 
)

Test that the chunk of code 'code' throws an expected exception.

'code' is a chunk of code to execute. It will be executed exactly once. If it throws an exception of type ExceptType, this test passes (and prints "passed"). Otherwise, it prints "failed" with an informative message. The macro prints all messages to the given output stream (std::ostream&) out. Furthermore, if the test passes, it assigns true to success; if the test fails, it assigns false to success.

The macro's implementation does not evaluate 'out' more than once.
