Module::Mask Description

Pretend certain modules are not installed Sometimes you need to test what happens when a given module is not installed. Module::Mask is a Perl module that provides a way of temporarily hiding installed modules from perl's require mechanism. The Module::Mask object adds itself to @INC and blocks require calls to restricted modules.Module::Mask will not affect modules already loaded at time of instantiation.SYNOPSIS use Module::Mask; { my $mask = new Module::Mask ('My::Module'); eval { require My::Module }; if ($@) { # ... should be called } else { warn "require succeeded unexpectedly" } } # The mask is out of scope, this should now work. eval { require My::Module }; # There's also an inverted version: { my $mask = new Module::Mask::Inverted qw( Foo Bar ); # Now only Foo and Bar can be loaded by require: eval {require Baz}; } Requirements: · Perl
