NAME
       TAP::Harness::Env - Parsing harness related environmental variables
       where appropriate
VERSION
       Version 3.42
SYNOPSIS
        my $harness = TAP::Harness::Env->create(\%extra_args)
DESCRIPTION
       This module implements the environmental variables that Test::Harness
       uses with TAP::Harness, and instantiates the appropriate class with the
       appropriate arguments.
METHODS
       o   create( \%args )
           This function reads the environment and generates an appropriate
           argument hash from it. If given any arguments in %extra_args, these
           will override the environmental defaults. In accepts
           "harness_class" (which defaults to "TAP::Harness"), and any
           argument the harness class accepts.
ENVIRONMENTAL VARIABLES
       "HARNESS_PERL_SWITCHES"
           Setting this adds perl command line switches to each test file run.
           For example, "HARNESS_PERL_SWITCHES=-T" will turn on taint mode.
           "HARNESS_PERL_SWITCHES=-MDevel::Cover" will run "Devel::Cover" for
           each test.
       "HARNESS_VERBOSE"
           If true, "TAP::Harness" will output the verbose results of running
           its tests.
       "HARNESS_SUBCLASS"
           Specifies a TAP::Harness subclass to be used in place of
           TAP::Harness.
       "HARNESS_OPTIONS"
           Provide additional options to the harness. Currently supported
           options are:
           "j<n>"
               Run <n> (default 9) parallel jobs.
           "c" Try to color output. See "new" in TAP::Formatter::Base.
           "a<file.tgz>"
               Will use TAP::Harness::Archive as the harness class, and save
               the TAP to "file.tgz"
           "fPackage-With-Dashes"
               Set the formatter_class of the harness being run. Since the
               "HARNESS_OPTIONS" is seperated by ":", we use "-" instead.
           Multiple options may be separated by colons:
               HARNESS_OPTIONS=j9:c make test
       "HARNESS_TIMER"
           Setting this to true will make the harness display the number of
           milliseconds each test took.  You can also use prove's "--timer"
           switch.
       "HARNESS_COLOR"
           Attempt to produce color output.
       "HARNESS_IGNORE_EXIT"
           If set to a true value instruct "TAP::Parser" to ignore exit and
           wait status from test scripts.
