Subject: TEST_IN_PARALLEL=1 make test

I'm rather fond of the ExtUtils::MakeMaker, other use the Modules::Build ... I hadn't prove until today and I wouldn't have tried it where it not for the new -j option. I'm wondering about an env var that enables tests in parallel from test_harness() so I can turn it on without prove.

Possibly, though it would have to be more than a simple boolean. However, enabling this for the *compatibility* layer may not be the best course. I would much rather see new versions of ExtUtils::MakeMaker and Module::Build use the TAP::Harness API directly (especially since many other various toolchain problems are solved by upgrading those -- so requiring that for the new features seems fair.) --Eric

I agree completely with Eric... *BUT* because we want people to be able to play with parallel testing as easily possible I've implemented an env variable called HARNESS_OPTIONS. Having worked with me for a little while I'm sure Eric expects that kind of ornery behaviour by now :) ===8<--- =item C<HARNESS_OPTIONS> Provide additional options to the harness. Currently supported options are: =over =item C<< j<n> >> Run <n> (default 9) parallel jobs. =item C<< f >> Use forked parallelism. =back Multiple options may be separated by colons: HARNESS_OPTIONS=j9:f make test ===8<--- That will be available in 3.02 or you can grab the latest source from I agree that it's ugly and that we want to steer people away from the Test::Harness legacy interface - but please test the parallel support and report any problems. Thanks for the suggestion.
