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
