Binary package “libtest-mockmodule-perl” in ubuntu bionic

Perl module to override subroutines in a module for unit testing

 Test::MockModule lets you temporarily redefine subroutines in other
 packages for the purposes of unit testing.
 .
 A Test::MockModule object is set up to mock subroutines for a given
 module. The object remembers the original subroutine so it can be
 easily restored. This happens automatically when all MockModule
 objects for the given module go out of scope, or when you unmock()
 the subroutine.
