Question

I had a method in a model:

class Article < ActiveRecord::Base
  def do_something
  end
end

I also had a unit test for this method:

This is more of a comment than an answer, but I put it here for the syntax highlighting...

I wanted a way to skip the callbacks in my tests, this is what I did. (This might help with the tests that broke.)

class Article < ActiveRecord::Base
  attr_accessor :save_without_callbacks
  after_save :do_something

  def do_something_in_db
    unless self.save_without_callbacks
      # do something here
    end
  end
end

# spec/models/article_spec.rb
describe Article do
  context "after_save callback" do
    [true,false].each do |save_without_callbacks|
      context "with#{save_without_callbacks ? 'out' : nil} callbacks" do
        let(:article) do
          a = FactoryGirl.build(:article)
          a.save_without_callbacks = save_without_callbacks
        end
        it do
          if save_without_callbacks
            # do something in db
          else
            # don't do something in db
          end
        end
      end
    end
  end
end
