DESCRIPTION

The methods in the Test::STD:Scrub package are designed to support the Test::STDmaker and the ExtUtils::SVDmaker package. This is the focus and no other focus. Since Test::STD::Scrub is a separate package, the methods may be used elsewhere. In all likehood, any revisions will maintain backwards compatibility with previous revisions. However, support and the performance of the Test::STDmaker and ExtUtils::SVDmaker packages has priority over backwards compatibility.

scrub_date_ticket


 $scrubbed_text = Test::STD::Scrub->scrub_date_ticket($script_text)

When comparing the contents of email messages, the date and email ticket should not be used in the comparision. The scrub_date_ticket method will replace the date and email ticket with a generic value. Applying the scrub_date_ticket to the contents of both files before the comparision will eliminate the data and ticket as factors in the comparision.

scrub_date_version


 $scrubbed_text = Test::STD::Scrub->scrub_date_version($script_text)

When comparing the contents of two Perl program modules, the date and version should not be used in the comparision. The scrub_date_ticket method will replace the date and version with a generic value. Applying the scrub_date_ticket to the contents of both files before the comparision will eliminate the date and version as factors in the comparision.

scrub_file_line


 $scrubbed_text = Test::STD::Scrub->scrub_file_line($script_text)

When comparing the ouput of Test module the file and line number should not be used in the comparision. The scrub_file_line method will replace the file and line with a generic value. Applying the scrub_file_line to the contents of both files before the comparision will eliminate the file and line as factors in the comparision.

scrub_test_file


 $scrubbed_text = Test::STD::Scrub->scrub_test_file($script_text)

When comparing the ouput of Test:Harness module the test file should not be used in the comparision. The scrub_test_file method will replace the test file with a generic value. Applying the scrub_test_file to the contents of both files before the comparision will eliminate the test file as a factor in the comparision.

QUALITY ASSURANCE

Running the test script 'Scrub.t' found in the ``Text-Scrub-$VERSION.tar.gz'' distribution file verifies the requirements for this module.

All testing software and documentation stems from the Software Test Description (STD) program module 't::Text::Scrub', found in the distribution file ``Text-Scrub-$VERSION.tar.gz''.

The 't::Text::Scrub' STD POD contains a tracebility matix between the requirements established above for this module, and the test steps identified by a 'ok' number from running the 'Scrub.t' test script.

The t::Text::Scrub' STD program module '__DATA__' section contains the data to perform the following:

  • to generate the test script 'Scrub.t'

  • generate the tailored STD POD in the 't::Text::Scrub' module,

  • generate the 'Scrub.d' demo script,

  • Replace the POD demonstration section herein with the demo script 'Scrub.d' output, and

  • run the test script using Test::Harness with or without the verbose option,

To perform all the above, prepare and run the automation software as follows:

  • Install ``Test_STDmaker-$VERSION.tar.gz'' from one of the respositories only if it has not been installed:
    
    
    
    =item *

    manually place the script tmake.pl in ``Test_STDmaker-$VERSION.tar.gz' in the site operating system executable path only if it is not in the executable path

  • place the 't::Text::Scrub' at the same level in the directory struture as the directory holding the 'Text::Scrub' module

  • execute the following in any directory:
    
     tmake -test_verbose -replace -run -pm=t::Text::Scrub


NOTES

FILES

The installation of the ``Text-Scrub-$VERSION.tar.gz'' distribution file installs the 'Docs::Site_SVD::Text_Scrub' SVD program module.

The __DATA__ data section of the 'Docs::Site_SVD::Text_Scrub' contains all the necessary data to generate the POD section of 'Docs::Site_SVD::Text_Scrub' and the ``Text-Scrub-$VERSION.tar.gz'' distribution file.

To make use of the 'Docs::Site_SVD::Text_Scrub' SVD program module, perform the following:

  • install ``ExtUtils-SVDmaker-$VERSION.tar.gz'' from one of the respositories only if it has not been installed:
  • manually place the script vmake.pl in ``ExtUtils-SVDmaker-$VERSION.tar.gz' in the site operating system executable path only if it is not in the executable path

  • Make any appropriate changes to the __DATA__ section of the 'Docs::Site_SVD::Text_Scrub' module. For example, any changes to 'Text::Scrub' will impact the at least 'Changes' field.

  • Execute the following:
    
     vmake readme_html all -pm=Docs::Site_SVD::Text_Scrub
