NAME

       Test::Without::Module - Test fallback behaviour in absence of modules

SYNOPSIS

         use Test::Without::Module qw( My::Module );

         # Now, loading of My::Module fails :
         eval { require My::Module; };
         warn $@ if $@;

         # Now it works again
         eval q{ no Test::Without::Module qw( My::Module ) };
         eval { require My::Module; };
         print "Found My::Module" unless $@;

DESCRIPTION

       This module allows you to deliberately hide modules from a program even though they are
       installed. This is mostly useful for testing modules that have a fallback when a certain
       dependency module is not installed.

   EXPORT
       None. All magic is done via "use Test::Without::Module LIST" and "no Test::Without::Module
       LIST".

   Test::Without::Module::get_forbidden_list
       This function returns a reference to a copy of the current hash of forbidden modules or an
       empty hash if none are currently forbidden. This is convenient if you are testing and/or
       debugging this module.

ONE LINER

       A neat trick for using this module from the command line was mentioned to me by NUFFIN and
       by Jerrad Pierce:

         perl -MTest::Without::Module=Some::Module -w -Iblib/lib t/SomeModule.t

       That way, you can easily see how your module or test file behaves when a certain module is
       unavailable.

BUGS

       ·   There is no lexical scoping

CREDITS

       Much improvement must be thanked to Aristotle from PerlMonks, he pointed me to a much less
       convoluted way to fake a module at <https://perlmonks.org?node=192635>.

       I also discussed with him an even more elegant way of overriding CORE::GLOBAL::require,
       but the parsing of the overridden subroutine didn't work out the way I wanted it -
       CORE::require didn't recognize barewords as such anymore.

       NUFFIN and Jerrad Pierce pointed out the convenient use from the command line to
       interactively watch the behaviour of the test suite and module in absence of a module.
