1.0 SCOPE

This paragraph identifies and provides an overview of the released files.

1.1 Identification

This release, identified in 3.2, is a collection of Perl modules that extend the capabilities of the Perl language.

1.2 System overview

The system is the Perl programming language software. As established by the Perl referenced documents, program modules, such the "Test::Tech" module, extend the Perl language.

The "Test::Tech" module extends the capabilities of the "Test" module.

The design is simple. The "Test::Tech" module loads the "Test" module without exporting any "Test" subroutines into the "Test::Tech" namespace. There is a "Test::Tech" cover subroutine with the same name for each "Test" module subroutine. Each "Test::Tech" cover subroutine will call the &Test::$subroutine before or after it adds any additional capabilities. The "Test::Tech" module is a drop-in for the "Test" module.

The "Test::Tech" module extends the capabilities of the "Test" module as follows:

  • If the compared variables are references, stingifies the referenced variable by passing the reference through Data::Dumper before making the comparison. Thus, Test::Tech can test almost any data structure. If the compare variables are not refernces, use the &Test::ok and &Test::skip directly.

  • Adds a method to skip the rest of the tests upon a critical failure

  • Adds a method to generate demos that appear as an interactive session using the methods under test

3.3 Changes

Changes are as follows:

Test-Tester-0.01

Originated.

Test-Tester-0.02

Minor changes to this SVD.

Test-Tech-0.01

Due to a non-registered namespace conflict with CPAN, changed the namespace from Test::Tester to Test::Tech

Test-Tech-0.02

Fixed prototype for &Test::Tech::skip_rest Test::Tech line 84

Test-Tech-0.03

The &Data::Dumper::Dumper subroutine stringifies the internal Perl variable. Different Perls keep the have different internal formats for numbers. Some keep them as binary numbers, while others as strings. The ones that keep them as strings may be well spec. In any case they have been let loose in the wild so the test scripts that use Data::Dumper must deal with them.

Added a probe to determine how a Perl stores its internal numbers and added code to the test script to adjust for the difference in Perl

Test::Tech 0.04
  • Added functions with the same name as the "Test" functions. This make it easier to upgrade from "Test" to "Test::Tech"

  • Added tests not only for Test 1.15 but also Test 1.24

  • Added tests for the new "Test" functions.

Test-Tech-0.05

Replaced using Test::Util that has disappeared with its replacements: File::FileUtil, Test::STD::Scrub, Test::STD::STDutil

Test-Tech-0.06

This version changes the previous version but eliminating all object methods. Since this module is built on the Test and the Data::Dumper modules, neither which are objectified, there is little advantage in providing methods where a large number of data is static for all objects. In other words, all new objects are mostly same.

Test-Tech-0.07
t/Test/Tech/Tech.t t/Test/Tech/techCO.t

Corrected typos in comments. More info in comments

Tech::Tech

Changed the test for TESTERR and Program_lines for setting in the tech_p hash from version number to if they are defined.

File::Util

Broke "File::FileUtil" apart into modules with more descriptive names. Switch to using the new modules "File::Package" and "File::SmartNL" instead of "file::FileUtil".

Test-Tech-0.09

Left over usage of File::FileUtil in the test script files. Removed them. Switch from "Test::STD::Scrub" to "Text::Scrub"

Test-Tech-0.11

In the test script, switch to using "Data::Hexdumper" module. Much better hex dumper.

Test-Tech-0.12

Removed hex dump in test script.

Change test for begining printout of data, modules used, tec to 1.20 < Test::VERSION

Change the test so that test support program modules resides in distribution directory tlib directory instead of the lib directory. Because they are no longer in the lib directory, test support files will not be installed as a pre-condition for the test of this module. The test of this module will precede immediately. The test support files in the tlib directory will vanish after the installtion.

Test-Tech-0.13

If there is no diagianotic message and there is a test name, then use the test name also for the diagnostic message. Diagnostic message appears in brackets after the expected value.

Test-Tech-0.14

Broke out the 'stringify' subroutine into its own module: 'Data::Strify'

Use Archive::TarGzip 0.02 that uses mode 777 for directories instead of 666. Started to get emails from Unix about untar not being able to change to a directory with mod of 666.

Test-Tech-0.15

Changed from using 'Data::Strify' to 'Data::Secs2' for the stringify function. 'Data::Secs2' is useful for SEMI clients and also provides sorted hash keys required for comparing stringifcation of Perl's nested data. The 'Data::Secs2' obsoletes 'Data::Strify' which is history.

Double checked that PREREQ_PM is 'Data::Secs2' which fixes Test-Tech-0.14 error in the PREREQ_PM which errorneous used by 'Data/Strify.pm' instead of 'Data::Strify'. This should clear complain by Mike Castle <dalgoda@ix.netcom.com> that the MakeFile.PL for Test-Tech-0.14 crashes with a divide by zero.

Test-Tech-0.16

Strange failure from cpan-testers

 Cc: SOFTDIA@cpan.org
 Subject: FAIL Test-Tech-0.15 sun4-solaris 2.8
 To: cpan-testers@perl.org 

Additional comments:

Hello, Samson Monaco Tutankhamen! Thanks for uploading your works to CPAN.

I noticed that the test suite seem to fail without these modules: Data::Secs2

As such, adding the prerequisite module(s) to 'PREREQ_PM' in your Makefile.PL should solve this problem. For example:

WriteMakefile( AUTHOR => 'Samson Monaco Tutankhamen (support@SoftwareDiamonds.com)', ... # other information PREREQ_PM => { 'Data::Secs2' => '0', # or a minimum workable version } );

The PREREQ_PM in the Test-Tech-0.15 MakeFile.PL is as follows:

 PREREQ_PM => {Data::Secs2 => 0.01},

Changed to

 PREREQ_PM => {'Data::Secs2' => '0.01'},
Test-Tech-0.17

The POD was citing &Data::Dumper::Dumper which was replaced by Data::Secs2::stringify. Changed the POD over to &Data::Secs2::stringify

The finish() subroutine was in the POD as a subroutine/method but not part of @EXPORT_OK. Add it to @EXPORT_OK.

Redirected all output from the 'Test::' module throught a handle Tie. The handle Tie added the test name on the same line as the 'ok' 'not ok' and collected stats.

Added printout of the stats to the finish() subroutine.

Added optional [@options] or {@options} input to the end of the ok subroutine and the skip subroutine.

Test-Tech-0.18

The test script could not find one of the test library program modules. Revamp the test script and test library modules and added steps to the ExtUtils::SVDmaker to have the SVDmaker test target run tests with just bare @INC that references a vigin Perl installation libraries only.

The lastest build of Test::STDmaker now assumes and expects the test library in the same directory as the test script. Coordiated with the lastest Test::STDmaker by moving the test library from tlib to t/Tie, the same directory as the test script and deleting the test library File::TestPath program module.

 Summary of my perl5 (revision 5.0 version 8 subversion 0) configuration:

This is capitalization problem. The program module name is 'FindBin' not 'FindBIN' which is part of Perl. Microsoft does not care about capitalization differences while linux does. This error is in the test script automatically generated by Test::STDmaker and was just introduced when moved test script libraries from tlib to the directory of the test script. Repaired Test::STDmaker and regenerated the distribution.

Test-Tech-0.20

FAILURE REPORT:

 Subject: FAIL Test-Tech-0.19 i586-linux 2.4.22-4tr 
 To: cpan-testers@perl.org 
 From: cpansmoke@alternation.net 
 Date: Sat, 10 Apr 2004 05:07:51 -0300 (ADT) 

[snip]

Can't locate Data/Secs2.pm in @INC

[snip]

As such, adding the prerequisite module(s) to 'PREREQ_PM' in your Makefile.PL should solve this problem. For example:

 WriteMakefile(
     AUTHOR      => 'Samson Monaco Tutankhamen (support@SoftwareDiamonds.com)',
     ... # other information
     PREREQ_PM   => {
        'Data::Secs2'   => '0', # or a minimum workable version
     }
 );

[snip]

CORRECTIVE ACTION:

An exam of MakeFile.PL revealed the following:

 WriteMakefile(
    # [snip]
    PREREQ_PM => {'Data::Secs2' => '0.01'},
    # [snip]
 );

Cannot see anything wrong with the PREREQ_PM statement. The only possibilities that come to mind are either CPAN not processing the prereq_pm properly, same syntax problem with PREREQ_PM or because the test script uses Test::Tech to test Test::Tech, the prereq is processed too late.

Added Data::Secs2 to the test library so the test will run.

Test-Tech-0.21

For Test module, version 1.20 or greater, changed so it sents failure messages when skip flag turned on for &Test::Tech::ok and &Test::Tech::ok out $Test::TESTERR instead of $Test::TESTOUT.

For &Test::Tech::finish automatically generate failure messages for all missing (not performed) test when the skip rest of tests flag is on.

The FindBIN that runs fine on Win because Win file spec is case insensitive and Unix whats case sensitive FindBin was fixed with on test Test::Test. However, overlooked all the test scripts that the top test script runs, grabs the output and compares to expected ouput stored in files. Corrected the FindBin for following test software: TechA0.t TechB0.t TechC0.t TechD0.d TechE0.t

Test-Tech-0.22

The Data::SecsPack program module is now required to run the Test::Tech program module. Added a print out of the Data::SecsPack version to the plan subroutine as follows:

 # Data::Secs2   : $Data::SecsPack::VERSION
Test-Tech-0.23

Added is_skip ok_sub and skip_sub subroutines.

Added reporting of Data::Secs2::stringify() errors. Correctly stringify Perl data structures is not straight forward. Unlike Test and Test::Tech, Data::Secs2 is very large including walks of Perl data structures, processing of underlying data types such as CODE and many other areas where there may be unanticipated Perl data structure issues not properly addressed. Thus, best to have error detection in place, and stop testing if there is a broken Data::Secs2::stringify().

Changed the look of the demo subroutine output to better resemble Perl code. Print the code straight forward without leading '=>'. Put a Perl comment '# ' in front of each result line instead of printing it straing forward.

Added a print out of the Data::Start version and number of tests to the plan subroutine.

Test-Tech-0.24

None of the test script for 0.23 ran. It appears that the Data::Secs2 does not load properly and, thus, none of the test scripts execute

 t/Test/Tech/Tech....Data::Secs2 version 1.22 required--this is only version 1.19 

Seen this before were CPAN has troubles with WriteMakefile subroutine in the MakeFile.PL

    PREREQ_PM => {'Data::Secs2' => '1.22',
                  'Data::SecsPack' => '0.06',
                  'Data::Startup' => '0.03',
                  'Test' => '1.20',},

Put the correct version in the test library, upload and see if this is the problem.

Test-Tech-0.25

It is unclear whether the failures to Test-Tech-0.24 is because of CPAN setup.

t/Test/Tech/Tech....Perl lib version (v5.8.4) doesn't match executable version (v5.6.1) at /usr/local/perl-5.8.4/lib/5.8.4/sparc-linux/Config.pm line 32. Compilation failed in require at /usr/local/perl-5.8.4/lib/5.8.4/FindBin.pm line 97.

Since cannot get a response from the tester, bump the version to force a retest.

Test-Tech-0.26

Changed Data::Secs2 so no longer loads Data::SecsPack unless needed. Test::Tech no longer loads Data::SecsPack via Data::secs2 so no longer print out its version. Instead print out the version of Data::Str2Num which is needed for the str2float and str2integer subroutines that the Data::SecsPack package supplied.

Compilation failed in require at techA0.t line 13.

Analysis:

Everything was going well until a `perl $command`. From same failure on other test scripts, the test harness perl executable is different than the command line perl executable.

Corrective Action:

Introduced the perl_command subroutine that uses $^X to return the current executable Perl into the test script. Use the results of this subroutine instead of 'perl' in backticks.

3.4 Adaptation data.

This installation requires that the installation site has the Perl programming language installed. There are no other additional requirements or tailoring needed of configurations files, adaptation data or other software needed for this installation particular to any installation site.

3.7 Possible problems and known errors

Known issues are as follows:

Merge with the "Test" module

The "Test::Tech" capabilites could be incorporated into the "Test" program module and "Test::Tech" eliminated.

TestLevel and Program_Lines

The "Test" module does not take the $TestLevel value into account where it chooses the module to load the %Program_Line hash. Since the Test::Tech module adds a module layer in between the Test module that the test script, the $TestLevel must be set to 1. Thus, the Test module loads the Test::Tech module into %Program_Line hash instead of the Module Under Test.
