Socialcast Shoulda Extensions

Adds new matchers and functionality to the shoulda test library

Installation

In your Gemfile:

group :test do
  gem 'socialcast_shoulda_ext', :git => 'git@github.com:socialcast/socialcast-shoulda-ext.git', :require => 'shoulda_ext'
end

If you want to include the trigger_callbacks matcher, also add the following to your test helper:

ShouldaExt::Matchers::TriggerCallbackMatcher.attach_active_record_callback_hooks!

Matchers

RecordCountChangeMatcher

Test if the count for a model has changed, and by how much. Requires the context_with_matcher_before_hooks patch, which is included by default.

Provides the following matcher methods:

  • create_record(klass_or_symbol) Alias for change_record_count.for(klass_or_symbol).by(1)

  • create_records(klass_or_symbol, amount) Alias for change_record_count.for(klass_or_symbol).by(amount)

  • destroy_record(klass_or_symbol) Alias for change_record_count.for(klass_or_symbol).by(-1)

  • destroy_records(klass_or_symbol, amount) Alias for change_record_count.for(klass_or_symbol).by(-amount)

  • change_record_count Tests the difference in record count before and after the current setup/subject block Can be used with the follow methods:

    • for(klass_or_symbol) Provides the class which the test is being performed on. Can be a constant or a symbol

    • by(amount) Provides an expected difference for the number of records for the specified class. Excluding this number will allow the matcher to check for any difference

Examples:

context "creating a blog article" do

  context "with good parameters" do
    setup do
      post :create, :blog => {:title => 'my blog post', :body => 'Ipsum lorem...'}
    end
    should create_record :blog
  end

  context "without a body" do
    setup do
      post :create, :blog => {:title => 'my blog post' }
    end
    should_not create_record Blog
  end

end

RespondWithJson

Check if the controller’s response is json

Examples:

context ":index.json" do
  setup do
    get :index, :format => 'json'
  end
  # Just check to see that the response was json
  should respond_with_json  

  # Evaluate the hash produced by the json yourself
  should respond_with_json { |json| json.first['blog']['title'] == 'blog post 1'}

  # Provide an exact match
  should respond_with_json.exactly(['blog' => {'id' => 1, 'title' => 'blog post 1'}])

  # Provide an exact match with a block
  should response_with_json.exactly{ |json| JSON.parse(Blog.all.to_json)}
end

context ":index.html" do
  setup do
    get :index
  end

  # or the negation
  should_not respond_with_json
end

TriggerCallbackMatcher

Test if create, update, destroy, or save callbacks were triggered.

Requires running ShouldaExt::Matchers::TriggerCallbackMatcher.attach_active_record_callback_hooks! in your test suite in order to work properly.

Examples:

context "doing nothing to a record" do
  subject { Blog.new :title => 'blog title' }
  should_not trigger_callbacks
end

context "creating a record" do
  subject { Blog.create! :title => 'blog title' }
  should trigger_callbacks.for :create
  should_not trigger_callbacks.for :update, :destroy
end

Integrations

Currently only integrates with test/unit. RSpec support to come.

Shoulda Extensions

ContextWithMatcherBeforeHooks

Adds the ability to define a ‘before’ method on any method which will be run before each context’s setup/subject block. Used by RecordCountChangeMatcher to record the number of records before the tested operation takes place.
