| Subject: | Tests cannot be executed in parallel |
When running with HARNESS_OPTIONS=j5, or "prove -j5 ...", tests randomly fail because scratch files and directories are shared across tests. Instead, File::Temp can be used to use a unique scratch directory for every test.
e.g.:
Building and testing File-ShareDir-Install-0.10
cp lib/File/ShareDir/Install.pm blib/lib/File/ShareDir/Install.pm
Manifying 1 pod document
PERL_DL_NONLAZY=1 "/Volumes/amaretto/Users/ether/perl5/perlbrew/perls/8.9/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
