Testing content_for Helper Methods with RSpec

application_helper_spec.rb

# Solution from http://www.jamiepenney.co.nz/2011/09/23/testing-content_for-in-rails-3-x-helpers-with-rspec/

describe ApplicationHelper do
  describe "title" do
    it "should return an h2 tag with the given title" do
      helper.title("Lorem Ipsum")
      helper.content_for(:page_title).should eql "<h2>Lorem Ipsum</h2>"
    end

    it "should return the supplied block if a block was given" do
      helper.title { "Some Block" }
      helper.content_for(:page_title).should eql "Some Block"
    end
  end
end

@cblunt Thanks, this was helpful. Didn't think that content_for could be called in the verify phase of a test using helper.content_for .

This is save my life. thanks
