TAP::Harness::Env

NAME

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

VERSION

Version 3.42

SYNOPSIS

  1.  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 seperated by : , we use - instead.

    Multiple options may be separated by colons:

    1.     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.
