If the \a expression - throws an exception and its type is the same as \a exceptiontype - or \a exceptiontype is substitutable with the type of thrown exception - (i.e. usually the type of thrown exception is publicly derived - from \a exceptiontype) then execution will be continued. If not-substitutable - type of exception is thrown or the \a expression doesn't throw an exception - at all, then a failure will be recorded in the test log and - the test won't be executed further. + The QVERIFY_EXCEPTION_THROWN macro executes \a expression + and tries to catch an exception thrown from \a expression. + + There are several possible outcomes: + + \list + \li If \a expression throws an exception that is either the same as + \a exceptiontype or derived from \a exceptiontype, then execution will continue. + + \li Otherwise, if \a expression throws no exception, or the + exception thrown derives from \c{std::exception}, then a failure + will be recorded in the test log and the macro returns early + (from enclosing function). + + \li If the thrown exception derives neither from \c{std::exception} nor from + \a exceptiontype, a failure will be recorded in the test log, and the exception is + re-thrown.
