Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

AddClassMethodTo checks whether a method was or not added to a class by the call of a block

This is used with a RSpec DSL method add_class_method(method_name).to(class_object)

Examples:

RSpec.configure do |config|
  config.include Sinclair::Matchers
end

class MyModel
end

describe 'my test' do
  let(:klass)   { Class.new(MyModel) }

  let(:block) do
    proc do
      klass.define_singleton_method(:parent_name) { superclass.name }
    end
  end

  it do
    expect(&block).to add_class_method(:parent_name).to(klass)
  end
end
