TAP::Harness::Env3perl

Usage

 my $harness = TAP::Harness::Env->create(\%extra_args)

Version

Version 3.52

Overview

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.
