NAME

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

CONTENTS

VERSION

Version 3.36

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.
