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

Version 3.43

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

This module implements the environmental variables that Test::Harness uses with TAP::Harness, and instantiates the appropriate class with the appropriate arguments.

• 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.

“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.
