DESCRIPTION:¶ ↑

Shave a few lines, but leave a little stubble. Stubble makes stubbing ORM models in rspec controller specs (or rails functional tests) just a little bit easier.

FEATURES/PROBLEMS:¶ ↑

Simple means of stubbing multiple ActiveRecord class and instance methods
Currently unreleased and somewhat experimental
- API and underlying functionality are subject to change
  - Especially while it's not yet released
Only works with RSpec's HEAD (see github.com/dchelimsky/rspec)
- I'll release 0.0.1 of stubble after the rspec-1.2.7 release
Works with RSpec or Test::Unit and multiple mock frameworks:
- RSpec's mocking framework (RSpec only)
- flexmock
- mocha
- rr

SYNOPSIS:¶ ↑

describe ThingsController do
  context "PUT with valid attributes"
    it "redirects to the things index" do
      stubbing(Thing) do
        put :update
        response.should redirect_to(things_path)
      end
    end
  end
end

CONFIGURATION:¶ ↑

RSpec¶ ↑

in spec_helper:

require 'stubble'
Stubble.configure {|c| c.stub_with(:rspec)}
Spec::Runner.configure {|c| c.include(Stubble)}

If you want to use any other mock framework (:mocha, :flexmock or :rr - example below with :rr):

require 'stubble'
Stubble.configure {|c| c.stub_with(:rr)}
Spec::Runner.configure do |c|
  c.include(Stubble)
  c.mock_with(:rr)
end

Test::Unit¶ ↑

in test_helper.rb

require 'stubble'
Stubble.configure {|c| c.stub_with(:mocha)}

class ActiveSupport::TestCase
  include Stubble
end

Same setup for :flexmock and :rr. Does not currently work with rspec's mock framework

USAGE:¶ ↑

By default, stubbled model classes are happy. They can be found, created, and saved in all number of ways without complaint.

stubbing(Thing) do |thing|
  ...
end

… stubs all the following:

Thing.new                 => thing
Thing.find(id)            => thing
Thing.find(:first)        => thing
Thing.find(:first, *args) => thing
Thing.create              => thing
Thing.create!             => thing

Thing.all                 => [thing]
Thing.all(*args)          => [thing]
Thing.find(:all)          => [thing]
Thing.find(:all, *args)   => [thing]

The instance of Thing is set up with the following stubs:

thing.valid?             => true
thing.save               => true
thing.save!              => true
thing.update_attribute   => true
thing.update_attributes  => true
thing.update_attributes! => true

You can also tell stubble to create an invalid stub, like so:

stubbing(Thing, :as => :invalid) do |thing|
  ...
end

This will respond to various finders, creators just like the default, with the exception of create!

Thing.create! => raise ActiveRecord::RecordInvalid

The instance returned is stubbed as follows:

thing.valid?             => false
thing.save               => false
thing.save!              => raise ActiveRecord::RecordInvalid
thing.update_attribute   => false
thing.update_attributes  => false
thing.update_attributes! => raise ActiveRecord::RecordInvalid

Examples¶ ↑

GET requests¶ ↑

The following examples will both pass if the controller's index action uses:

find(:all)

all

describe "things" do
  context "successful GET"
    it "assigns things" do
      stubbing(Thing) do |thing|
        get :index
        assigns[:things].should == [thing]
      end
    end
  end
end

POST requests¶ ↑

The following examples will both pass if the controller's index action uses:

new
create
create!
valid?
save

save!

describe "things" do
  context "successful POST"
    it "creates a new thing" do
      stubbing(Thing) do |thing|
        post :create
        assigns[:things].should == [thing]
      end
    end
  end
end

PUT requests¶ ↑

The following examples will both pass if the controller's update action uses find with any of:

update_attribute + (save || save!)
update_attributes

update_attributes!

describe "things" do
  context "successful PUT"
    it "redirects to the things index" do
      stubbing(Thing) do
        put :update
        response.should redirect_to(things_path)
      end
    end
  end

  context "failed PUT"
    it "re-renders the edit page" do
      stubbing(Thing, :as => :invalid) do
        put :update
        response.should render_template('edit')
      end
    end
  end
end
