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