Module: Spec::Example::ModuleReopeningFix

Included in:
ExampleMethods
Defined in:
lib/spec/example/module_reopening_fix.rb

Overview

When you reopen a module that is included in another module that is included in a class, the new material you define does not make it to the class. This fixes that.

Example

module M1; end

module M2
  def foo; "FOO"; end
end

class C
  include M1
end

module M1
  include M2
end

c = C.new
c.foo
NoMethodError: undefined method `foo' for #<C:0x5e89a4>
  from (irb):12
