TAP::Harness::Env(3pm)

NAME
TAP::Harness::Env - Parsing harness related environmental variables where appropriate

VERSION
Version 3.50

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

•   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 separated 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.
