Check that Exception_Message, +-- Exception_Identity, Exception_Name, and Exception_Information raise +-- Constraint_Error for a Null_Occurrence input parameter. +-- Check that calling the Save_Occurrence subprograms with the +-- Null_Occurrence input parameter saves the Null_Occurrence to the +-- appropriate target object, and does not raise Constraint_Error. +-- Check that Null_Id is the default initial value of type Exception_Id. +-- +-- TEST DESCRIPTION: +-- This test performs a series of calls to many of the subprograms +-- defined in package Ada.Exceptions, using either Null_Id or +-- Null_Occurrence (based on their parameter profile). In the cases of +-- Raise_Exception and Reraise_Occurrence, these null input values +-- should result in no exceptions being raised, and Constraint_Error +-- should not be raised in response to these calls. Test failure will +-- result if any exception is raised in these cases. +-- For the Save_Occurrence subprograms, calling them with the +-- Null_Occurrence input parameter does not raise Constraint_Error, but +-- simply results in the Null_Occurrence being saved into the appropriate +-- target (either a Exception_Occurrence out parameter, or as an +-- Exception_Occurrence_Access value). +-- In the cases of the other mentioned subprograms, calls performed with +-- a Null_Occurrence input parameter must result in Constraint_Error +-- being raised. This exception will be handled, with test failure the +-- result if the exception is not raised. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 08 Dec 00 RLB Removed Exception_Identity subtest, pending +-- resolution of AI95-00241. +-- Notes for future: Replace Exception_Identity +-- subtest with whatever the resolution is. +-- Add a subtest for Exception_Name(Null_Id), which +-- is missing from this test. +--! + +with Report;
