NAME¶

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

VERSION¶

Version 3.44

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:

    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.
