Testing ActiveAdmin with rspec

activeadmin, rspec, rspec-rails, rspec2

Solution

This is the way I did it that worked for me:-

app/admin/posts.rb

ActiveAdmin.register Post do

  menu :parent => "Admin"


  #path = /admin/posts/:id/comments
  member_action :comments do
   @post = Post.find(params[:id])
  end 
end

spec/controllers/admin/posts_controller_spec.rb

require 'spec_helper'
include Devise::TestHelpers


describe Admin::PostsController do
  render_views

  before(:each) do
    @user = mock_model(User, :email => "tester@localspecs.com")
    request.env['tester'] = mock(Tester, :authenticate => @user, :authenticate! => @user)
  end

  describe "Get comments" do
    before(:each) do
      @post = Post.create! valid_attributes
      Post.should_receive(:find).at_least(:once).and_return(@post)
      get :comments, :id => @post.id
    end

    after(:each) do
      @post.destroy
    end

    it "gets the proper record to update" do
      assigns(:post).should eq(@post)
    end

    it "should render the actual template" do
      response.should contain("Comments")
      response.body.should =~ /Comments/m
    end
  end
end

Problem
