I run ./Build testcover The coverage only inside of directory blib is useful. I have to wait a very long time and the result is extremly big.

Is this a Devel::Cover bug or something related to how Module::Build is calling it? Thanks, Eric

Should I open a ticket at Devel::Cover now? Tell me. But I do not realy know, how Devel::Cover is called of Module::Build. It would be more professional if a Module::Build author can do this.

Hi Steffen, You can look in Module/Build/Base.pm at the ACTION_testcover() method to see what is being done. The Devel::Cover documentation has some notes on selecting files. It may have to do with: "The inc directories are initially populated with the contents of the @INC array at the time Devel::Cover was built" As I notice you've got 'D:\' involved. Which means this may be an ActiveState bug. Discussing this on a mailing list would allow more people to answer than just me. Thanks, Eric
Subject: testcover not working with TAP::Harness
Download (untitled) / with headers
text/plain 815b
If I just run ./Build testcover, it hangs at test 3 in t/basic.t If I force usage of TAP::Harness API, I think this doesn't actually check the coverage, but because this is an environment variable and the ./Build testcover --use-tap-harness 191s later Can't open database /usr/local/code/hop_others/mb.alt/cover_db PERL5LIB=$OVER_THERE/Test-Harness-2.64/lib/:$PERL5LIB \ ./Build testcover 1906s later ... omg forever! Now I have a coverage report for TAP::Parser and Module::Build? And apparently better test coverage for TAP::Base than Module::Build::Base :-) Probably the thing to do here is to tear out the usage of the Test::Harness API completely and maybe use PERL5OPT to -MDevel::Cover. The trick being that most of the M::B test suite that actually exercises M::B uses system().

Hi Steffen, Have you had a chance to investigate this at all? I think it may be related to our own inability to run testcover. https://rt.cpan.org/Ticket/Display.html?id=39230 In some situations, I'm able to get better results using the --use-test-harness flag. Could you please try that with a new M::B release? Thanks, Eric

Hello Eric, I had installed Module::Build version 0.31, the highest, I can get as an ppm package. I have no idea where I should place the --use-test-harness flag. When I call Build testcover it will be useful if I could write Build testcover -ignore . -select blib/lib and you run require Devel::Cover; Devel::Cover->import('-ignore' => '.', '-select' => 'blib/lib'); or something like that. --Steffen
