response.should have_text leads to undefined method `has_text?'

Question
I would like to test a controller that directly renders some JSON output (by using "render :json => @entity_names"). For that task I tried in my spec file "response.should have_text('["enim", "enita"]')". Unfortunately I always get that error: Failure/Error: response.should have_text('["enim", "enita"]') undefined method `has_text?' for #
Do I miss some gem that provides that method? Here my Gemfile:
source 'http://rubygems.org'
gem 'rails', '>= 3.0.0'
gem 'mysql2'
gem 'mongrel'
gem 'devise'
gem 'will_paginate', :git => 'git://github.com/mislav/will_paginate.git', :branch => 'rails3'
gem 'thinking-sphinx', :git => 'git://github.com/freelancing-god/thinking-sphinx.git', :branch => 'rails3', :require => 'thinking_sphinx'
group :test, :development do
gem 'rspec-rails', '>= 2.0.0.beta.19'
gem 'steak', :git => 'git://github.com/cavalle/steak.git'
gem 'webrat'
gem 'capybara'
gem 'capybara-envjs'
gem 'shoulda'
gem 'launchy'
gem 'autotest'
gem 'autotest-rails'
gem 'test_notifier'
gem 'rails3-generators'
gem 'factory_girl_rails'
gem 'populator'
gem 'faker'
gem 'random_data'
gem 'database_cleaner', :git => 'git://github.com/bmabey/database_cleaner.git'
gem 'delorean'
end
Solution
You could construct your expected output as JSON, then get the response body (which is also JSON), decode both, and compare them. Something like:
it "should do something" do
expected = { :some_key => "and some value" }.to_json
xhr :post, :create, { :foo => "bar" }
ActiveSupport::JSON.decode(response.body).should == ActiveSupport::JSON.decode(expected)
end
