[Perlunit-devel] compile errors and Loader

[Adam S. <ad...@sp...>]

Test::Unit::Loader is doing all the work of compiling in suites and
cases etc., and mostly works very nicely.  However, the load() method
has an oddity:

    } elsif ($@ !~ /^Can\'t locate .* in \@INC \(\@INC contains/) {
        die $@;
    } else {
        print "Debug: ".$@ if DEBUG;
    }

which means that if your test case tries to use another module
unsuccessfully (e.g. if the module name has a typo), then it falls
through the above block without doing anything (except outputting some
debugging if DEBUG is on).  That means the user sees:

  >> Tests::GGconfig
  (This error is expected) Suite class Tests::GGconfig not found: Can't
  locate GGconfg.pm in @INC (@INC contains: .....

which is misleading.  Changing that code to

    } else {
        die $@;
    }

yields:

    >> Tests::GGconfig
    Can't locate GGconfg.pm in @INC (@INC contains: .....

which is exactly what the user needs to see.  What was the reasoning
behind hiding those "Can't locate" errors?
