ACTS-AS-FU

Now you have no excuse for not test-driving your ActiveRecord extending plugins.

Usage

In your spec_helper.rb (pretty sure this works with Test::Unit too, I'll leave you to figure it out though)

require 'rubygems'
require 'acts_as_fu'
require 'spec'

Spec::Runner.configure do |config|
  config.include ActsAsFu
end

Then in your specs:

describe "acts_as_gilmore_girls" do
  before(:each) do
    build_model :nerds do
      text :omg_omg_bio
      string :name
      string :favorite_scene

      validates_presence_of :favorite_scene

      def awesome?(show_name)
        show_name == "Gilmore Girls"
      end      
    end
  end

  it "should require favorite scene" do
    nerd = Nerd.new :favorite_scene => nil
    nerd.should_not be_valid
    nerd.errors.on(:favorite_scene).should_not be_nil
  end

  it "should think gilmore girls is awesome"
    nerd = Nerd.new
    nerd.awesome?("Gilmore Girls").should be_true
  end

  it "has other stuff" do
    # ETC!
  end
end

The build_model method allows you to build an ActiveRecord model on the fly. It takes a block where you can specify columns and methods.

Single Table Inheritance

If you want to create a model that's a subclass of another, you can use the :superclass option:

build_model(:assets) do
  string :type
  string :name
  named_scope :pictures, :conditions => { :type => "Picture" }
end

build_model(:pictures, :superclass => Asset)

The Picture model will then be a subclass of the Asset model.

Custom database configuration

If the in-memory sqlite3 database doesn't suit your needs, you can specify an alternative configuration with the ActsAsFu.connect! method:

ActsAsFu.connect! \
  :adapter => 'mysql',
  :database => 'some-db',
  :username => 'some-user',
  :password => 'some-password',
  :socket => '/path/to/mysql.sock'

Install

$ gem install nakajima-acts_as_fu --source=http://gems.github.com

TODO

Provide the ability to create multiple connections (thanks to Pivotal for the idea):

ActsAsFu.connections[:sqlite3] # or something
