|
|
|
26 -- OBJECTIVE:
|
|
|
27 -- Check that Raise_Exception and Reraise_Occurrence have no effect in
|
|
|
28 -- the case of Null_Id or Null_Occurrence. Check that Exception_Message,
|
|
|
29 -- Exception_Identity, Exception_Name, and Exception_Information raise
|
|
|
30 -- Constraint_Error for a Null_Occurrence input parameter.
|
|
|
31 -- Check that calling the Save_Occurrence subprograms with the
|
|
|
32 -- Null_Occurrence input parameter saves the Null_Occurrence to the
|
|
|
33 -- appropriate target object, and does not raise Constraint_Error.
|
|
|
34 -- Check that Null_Id is the default initial value of type Exception_Id.
|
|
|
35 --
|
|
|
36 -- TEST DESCRIPTION:
|
|
|
37 -- This test performs a series of calls to many of the subprograms
|
|
|
38 -- defined in package Ada.Exceptions, using either Null_Id or
|
|
|
39 -- Null_Occurrence (based on their parameter profile). In the cases of
|
|
|
40 -- Raise_Exception and Reraise_Occurrence, these null input values
|
|
|
41 -- should result in no exceptions being raised, and Constraint_Error
|
|
|
42 -- should not be raised in response to these calls. Test failure will
|
|
|
43 -- result if any exception is raised in these cases.
|
|
|
44 -- For the Save_Occurrence subprograms, calling them with the
|
|
|
45 -- Null_Occurrence input parameter does not raise Constraint_Error, but
|
|
|
46 -- simply results in the Null_Occurrence being saved into the appropriate
|
|
|
47 -- target (either a Exception_Occurrence out parameter, or as an
|
|
|
48 -- Exception_Occurrence_Access value).
|
|
|
49 -- In the cases of the other mentioned subprograms, calls performed with
|
|
|
50 -- a Null_Occurrence input parameter must result in Constraint_Error
|
|
|
51 -- being raised. This exception will be handled, with test failure the
|
|
|
52 -- result if the exception is not raised.
|
|
|
53 --
|
|
|

|
|
|
55 -- CHANGE HISTORY:
|
|
|
56 -- 06 Dec 94 SAIC ACVC 2.0
|
|
|
57 -- 08 Dec 00 RLB Removed Exception_Identity subtest, pending
|
|
|
58 -- resolution of AI95-00241.
|
|
|
59 -- Notes for future: Replace Exception_Identity
|
|
|
60 -- subtest with whatever the resolution is.
|
|
|
61 -- Add a subtest for Exception_Name(Null_Id), which
|
|
|
62 -- is missing from this test.
