ACATS Test Modification List

ACATS Test Modification List

Version 4.1N
September 27, 2019

What is this?

This is the ACATS modification list for ACATS 4.1. This document includes test corrections, test removals, and new tests for ACATS 4.1. ACATS 4.1 is the current test suite for Ada, covering the third edition of Ada, ISO/IEC 8652:2012 (usually known as "Ada 2012").

ACATS Modification List version 3.1X for ACATS 3.1 is the current list for that test suite. ACATS 3.1 should be used for testing implementations that support Amendment 1 (ISO/IEC 8652:1995/AMD 1:2007, often known as "Ada 2005"), and will continue to be maintained as necessary for the foreseeable future.

ACATS Modification List version 2.6G for ACATS 2.6 is the current list for that test suite. ACATS 2.6 should be used for testing implementations of the second edition of Ada, ISO/IEC 8652:1995 (usually known as "Ada 95"); it also will continue to be maintained as necessary for the foreseeable future.

Changes from the last list:

A handful of tests changed status on July 1st; see the lists for the details.

Test C415001 was corrected to eliminate an accessibility error in Fetch.

Test B551002 was modified to remove an unnecessary dependence on Ada.Iterator_Interfaces.

Test B631001 was created to check that a prefixed view is intrinsic.

New tests posted between July 1, 2019 and September 30, 2019 will become required for conformity assessments on April 1, 2020. New tests posted between April 1, 2019 and June 30, 2019 will become required for conformity assessments on January 1, 2020. New tests posted between January 1, 2019 and March 31, 2019 will become required for conformity assessments on October 1, 2019. New tests posted before January 1, 2019 are required for conformity assessments. The effective dates of tests are marked in the lists.

ACATS 4.1 includes optional Test Grading tools

ACATS 4.1 introduces new test grading tools.

When the ACATS was designed (as the ACVC in the early 1980s), the intention always was that running it would give a simple and clear Pass or Fail result. However, grading of tests (particularly of B and L Tests) is somewhat subjective and very time-consuming. (Test grading typically involved poring over compiler listings of the entire ACATS with a large highlighter.) The subjectivity was acceptable in the days of common formal testing, as the formal testers would enforce a common grading standard (even if no one could describe what that was), but in an age of self-testing, it reduces the value of the ACATS.

As such, we're introducing a long-overdue set of automated grading tools. These tools are intended to:

Greatly reduce the effort to grade an ACATS test run (and, hopefully to reduce the cost of formal testing to make it a more practical option);
Ensure that all users of the ACATS grade tests in the same way, thus making it more valid to compare ACATS results between different implementations and different testers;
Give implementers certainty as to whether a particular test result is passing (whether the location of an error is "close enough" to the canonical position);
Be able to detect process errors (especially errors of omission) – that is, tests improperly run (for instance, files compiled in the wrong order where the ACATS requires an order), or not run at all (if one is checking off lines in a listing, it's hard to notice that some test or portion of a test is missing).

The tools also will optionally give feedback to implementers about quality of error message positioning and of error cascades (does one error generate multiple messages?). (Since "goodness of an implementation" is not something that the ACATS tests for, this is not an official goal for the tools.)

This is an ambitious set of goals. It's unlikely that they'll be completely met by the initial versions of the tools. As such, their use will be completely optional (but encouraged!) for ACATS 4.1. The tools will be updated periodically by the normal process for updating the ACATS – an ACATS Modification List like this one.

Details on the operations of the tools can be found in the ACATS 4.1 documentation (that documentation can be found at http://www.ada-auth.org/acats-files/4.1/docs/UG-6.HTM). As always, if you have questions, contact the ACAA Technical Agent at agent@ada-auth.org.

Notice:

The ACAA has created and maintains the Ada Conformity Assessment Test Suite for the purpose of conformity assessments conducted in accordance with the International Standard ISO/IEC 18009 - Ada: Conformity assessment of a language processor. This test suite should not be used to make claims of conformance unless used in accordance with ISO/IEC 18009 and any applicable ACAA procedures.

List explanation:

Test numbers given are for the basic test. Categories are "Withdrawn" (the test should not be processed for Ada conformity assessments); "Allowed Modification" (either the original test or the modified one should be processed for Ada conformity assessments); "Modified" (the modified test must be processed for Ada conformity assessments); "Pending New" (the test does not need to be processed for Ada conformity assessments, but will be added in the future); "New" (the test is processed for Ada conformity assessments).

ACATS version labels are provided with all new and modified tests. Use this label to retrieve the test from the ACATS VCS. See "How to get new and modified tests".

In citations, line numbers are given relative to the start of a test file in the format of '@<line#,line#,...>'; if a test program comprises more than one file, then the particular file will be indicated by "fn", where "n" is the test-program name's file-designator numeral. E.g., "B38103E : @f1-31, ... " denotes test file b38103e1.ada. In cases where there are two or more rationales for different errors in a test program, these different rationales with their respective line citations are listed on separate lines. References to the Ada standards are given in the format:
<section|chapter>.<clause>[.<subclause>]:<paragraph>
These references are to the consolidated Ada standard as available at http://www.ada-auth.org/standards/rm12_w_tc1/html/RM-TOC.html.

        and thus not subject to the rule. The declaration of Shine @149
        never overrides primitives of the actual type by 12.3(18), thus
        this rule does not apply to instances of Gen2. Added an example
        using a generic derived type.

        the rules of the ACATS User's Guide, clause 4.3.3.

C611B02 [New] VCS Label: A4_1A
        [VCS Label A4_1A] Check that X'Old has the tag of X and not the
        tag of the nominal subtype of X (for Post'Class).
        [VCS Label A4_1C] The main subprogram name was corrected to follow

===== Support =====

F611A00 [New] VCS Label: A4_1C
        [VCS Label A4_1A] Foundation for tests C611A01, C611A02, and
        C611A03.
        [VCS Label A4_1C] Added additional data for test C611A04. The
        changes are only needed for that test.

F611B00 [New] VCS Label: A4_1A
        Foundation for tests C611B01, C611B02, and C611B03.

GRADE.A [Modified] VCS Label: A4_1G
        [VCS Label A4_1C] Allowed manual grading for tests that are
        missing execution or linking (with no earlier errors). Corrected
        the result for binder crashes. Added category totals to the
        summary.
        [VCS Label A4_1D] Corrected so that Annex C RQMT failures are
        properly counted in their own category.
        [VCS Label A4_1G] Corrected call @1578 so that the special
        handling flag rather than the failed flag is used with a manual
        grading message for a missing error set. (The actual grade was
        correct, only the message was wrong.)

GRD_DATA.A [Modified] VCS Label: A4_1D
        Increased table sizes as the new tests have caused grading the
        entire ACATS to exceed the old limits.

GRD_DATA.A [Allowed Modification] New VCS Label: A4_1M Org VCS Label: A4_1D
                    Required after 2019-10-01
        Generalized reading of white space in order to be more resilient,
        especially on Unix-like systems.

        [VCS Label A4_1C] Added test BA21005 to the list of optional main
        subprograms.
        [VCS Label A4_1H] Added seven tests to the list of optional main
        subprograms.
        [VCS Label A4_1J] Added more tests to the list of optional main 
        subprograms.

SUMMARY.A [Modified] VCS Label: A4_1C
        Corrected identification of main subprograms in modern tests.
        Changed the unit name for subunits to be the full expanded name
        including the parent name.

TCTOUCH.ADA [Modified] VCS Label: A4_1H
        Added code so that Touch only reports buffer overflow once. Fixed
        the Id string.

How to get new and modified tests:

The official home of the ACATS test suite is the ACAA web site. The site can be accessed at www.ada-auth.org.

The complete set of official new and modified tests are available in the Mod_4_1N.Zip and Tar files on the ACAA web site. As always, when a multi-file test is modified, we provide all of the files, including the unmodified files

Individual new and modified tests can be retrieved from the ACATS VCS. Simply navigate to the appropriate directory (folder), and select the test you want. Select the revision you want (usually the most recent) and it will be retrieved for you. Tests are stored in directories that correspond to the test's prefix. For instance, the test CD92001.A will be found in the CD directory. You can also browse the differences between versions of a test. [In case of a conflict, the files in the ACATS VCS should be considered the 'official' versions.]

If you cannot get the files from the official site or you cannot get the files in a format appropriate for your processor, please contact your ACAL.

The baseline ACATS 4.1 is available in various formats on the ACAA web site.
