cpanplus test suite seems to be a bit ruinous

[Intrepid]

The Seekers of Perl Wisdom may not be the best place in the known universe for a bug report, but I know the maintainer of the module I am struggling with, bingos, is active here. So here goes.

The test suite for cpanplus is the creature we need to tame.

I am working with cpanplus v0.9916 and on CygwinPerl v5.40.2

First off, Params::Validate reports an error, exact text shown below, in Dist/MM.pm:

Key 'dir' (t/20_CPANPLUS-Dist-MM.t) is of invalid type for 'CPANPLUS::Internals::Utils::_chdir' provided by CPANPLUS::Dist::MM::create at /cygdrive/c/Users/somia/AppData/Local/.cpanp/.cpanplus/5.40.2/build/nDoXKs5RLj/CPANPLUS-0.9916/t/../lib/CPANPLUS/Dist/MM.pm line 610.

I inserted some dumb simple code to check what is being passed, the output is:

----------------------------------------------------------------------------
Args being passed to Params::Validate: dir|t/20_CPANPLUS-Dist-MM.t
----------------------------------------------------------------------------

I will provide a plate of Buffalo chicken wings to the monk or nun that can work out why that error is appearing. ;-) I've looked and looked and cannot figure it out.

The next matter is equally baffling. I have DBD::SQLite installed to my system but the test suite reports skipping test because "SQLite engine not available":

t/031_CPANPLUS-Internals-Source-SQLite.t ...... skipped: SQLite engine not available
t/032_CPANPLUS-Internals-Source-via-sqlite.t .. skipped: SQLite engine not available

Lastly, the tests in the suite themselves seem to be out of order somehow:

Anyone able to provide suggestions for how to seek and destroy these annoying errors will have my sincere gratitude.

I don't use cpanplus, but i know that the "normal" cpan uses CPAN::SQLite. Try installing that one.

I forgot that CPAN-cpan uses CPAN::SQLite, cavac, but CPANPLUS-cpan appears not to:

$ perl -w -MCPANPLUS -le'print "$/$_" for values %INC' | grep CPANPLUS
+ | xargs -l grep SQLite
                    'DBD::SQLite'  => '0.0',
                        eq 'CPANPLUS::Internals::Source::SQLite'

As you see above I did a quick-and-dirty grep peek into CPANPLUS and it uses DBD::SQLite.

I've done a bit more poking around in the code to see if I can get cpanplus to use SQLite. I discovered that the line found above by grep, 'DBD::SQLite' => '0.0',, is preceded by the line containing 'DBIx::Simple' => '0.0',. I installed DBIx::Simple and the result is that when I make test on CPANPLUS it seems happy to use SQLite. Here's a part of the code I'm talking about, in /CPANPLUS/Selfupdate.pm:

            sqlite_backend => [
                {   'DBIx::Simple' => '0.0',
                    'DBD::SQLite'  => '0.0',
                },
                sub {
                    my $cb   = shift;
                    my $conf = $cb->configure_object;
                    return $conf->get_conf('source_engine')
                        eq 'CPANPLUS::Internals::Source::SQLite'
                },
