Shoulda::Matchers::ActionController

By using the matchers you can quickly and easily create concise and easy to read test suites.

This code segment:

describe UsersController, 'on GET to show with a valid id' do
  before(:each) do
    get :show, :id => User.first.to_param
  end

  it { should respond_with(:success) }
  it { should render_template(:show) }
  it { should not_set_the_flash) }

  it 'does something else really cool' do
    assigns[:user].id.should == 1
  end
end

Would produce 5 tests for the show action
