NAME ^

Test::Tech - adds skip_tests and test data structures capabilities to the "Test" module

SYNOPSIS ^

 use Test::Tech

 @args    = tech_config( @args );

 $success = plan(@args);

 $test_ok = ok(\@actual_results, \@expected_results, $diagnostic, $test_name);
 $test_ok = skip($skip_test, \@actual_results,  \@expected_results, $diagnostic, $test_name);

 $test_ok = ok($actual_results, $expected_results, $diagnostic, $test_name);
 $test_ok = skip($skip_test, $actual_results,  $expected_results, $diagnostic, $test_name);

 $state = skip_tests( $on_off );
 $state = skip_tests( );

 $string = stringify( $var );

DESCRIPTION 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::Tester" module extends the capabilities of the "Test" module as follows:

The Test::Tech module is an integral part of the US DOD SDT2167A bundle of modules. The dependency of the program modules in the US DOD STD2167A bundle is as follows:

 File::Package
   File::SmartNL Test::STD::Scrub
     Test::Tech
        DataPort::FileType::FormDB DataPort::DataFile Test::STD::STDutil
            Test::STDmaker ExtUtils::SVDmaker

plan subroutine

 $success = plan(@args);

The plan subroutine is a cover method for &Test::plan. The @args are passed unchanged to &Test::plan. All arguments are options. Valid options are as follows:

tests

The number of tests. For example

 tests => 14,
todo

An array of test that will fail. For example

 todo => [3,4]
onfail

A subroutine that the Test module will execute on a failure. For example,

 onfail => sub { warn "CALL 911!" } 

ok subroutine

 $test_ok = ok(\@actual_results, \@expected_results, $test_name);
 $test_ok = ok($actual_results, $expected_results, $test_name);

The test method is a cover function for the &Test::ok subroutine that extends the &Test::ok routine as follows:

skip subroutine

 $test_ok = skip(\@actual_results, \@expected_results, $test_name);
 $test_ok = skip($actual_results, $expected_results, $test_name);

The skip subroutine is a cover function for the &Test::skip subroutine that extends the &Test::skip the same as the ok subroutine subroutine extends the &Test::ok subroutine.

skip_tests method

 $state = skip_tests( $on_off );
 $state = skip_tests( );

The skip_tests subroutine sets a flag that causes the ok and the skip methods to skip testing.

stringify subroutine

 $string = stringify( $var );

The stringify subroutine will stringify $var using the "Data::Dumper" module only if $var is a reference; otherwise, it leaves it unchanged.

For numeric arrays, "Data::Dumper" module will not stringify them the same for all Perls. The below Perl code will produce different results for different Perls

 $probe = 3;
 $actual = Dumper([0+$probe]);

For Perl v5.6.1 MSWin32-x86-multi-thread, ActiveState build 631, binary, the results will be '[\'3\']' while for Perl version 5.008 for solaris the results will be '[3]'.

This module will automatically, when loaded, probe the site Perl and will this statement and enter the results as 'string' or 'number' in the Internal_Number configuration variable.

tech_config subroutine

 $old_value = tech_config( $dot_index, $new_value );

The tech_config subroutine reads and writes the below configuration variables

 dot index              contents 
 --------------------   --------------
 Dumper.Terse          \$Data::Dumper::Terse
 Dumper.Indent         \$Data::Indent
 Dumper.Purity         \$Data::Purity
 Dumper.Pad            \$Data::Pad
 Dumper.Varname        \$Data::Varname
 Dumper.Useqq          \$Data::Useqq
 Dumper.Freezer        \$Data::Freezer
 Dumper.Toaster        \$Data::Toaster
 Dumper.Deepcopy       \$Data::Deepcopy
 Dumper.Quotekeys      \$Data::Quotekeys
 Dumper.Maxdepth       \$Data::Maxdepth
 Test.ntest            \$Test::ntest
 Test.TESTOUT          \$Test::TESTOUT
 Test.TestLevel        \$Test::TestLevel
 Test.ONFAIL           \$Test::ONFAIL
 Test.todo             \%Test::todo
 Test.history          \%Test::history
 Test.planned          \$Test::planned
 Test.FAILDETAIL       \@Test::FAILDETAIL
 Test.Program_Lines    \%Test::Program_Lines
 Test.TESTERR          \$Test::TESTERR
 Skip_Tests            # boolean
 Internal_Number       # 'string' or 'number'

The tech_config subroutine always returns the $old_value of $dot_index and only writes the contents if $new_value is defined.

The 'SCALAR' and 'ARRAY' references are transparent. The tech_config subroutine, when it senses that the $dot_index is for a 'SCALAR' and 'ARRAY' reference, will read or write the contents instead of the reference.

The The tech_config subroutine will read 'HASH" references but will never change them.

The variables for the top level 'Dumper' $dot_index are established by "Data::Dumper" module; for the top level 'Test', the "Test" module.
