Module: Remarkable::ActiveRecord::Describe

Defined in:

lib/remarkable/mongo_mapper/describe.rb

Overview

Overwrites describe to provide quick way to configure your subject:

describe Post
should_validate_presente_of :title

describe :published => true do
  should_validate_presence_of :published_at
end
end

This is the same as:

describe Post
should_validate_presente_of :title

describe "when published is true" do
  subject { Post.new(:published => true) }
  should_validate_presence_of :published_at
end
end

The string can be localized using I18n. An example yml file is:

locale:
remarkable:
  mongo_mapper:
    describe:
      each: "{{key}} is {{value}}"
      prepend: "when "
      connector: " and "

You can also call subject attributes to set the default attributes for a subject. You can even mix with a fixture replacement tool:

describe Post
# Fixjour example
subject_attributes { valid_post_attributes }

describe :published => true do
  should_validate_presence_of :published_at
end
end

You can retrieve the merged result of all attributes given using the subject_attributes instance method:

describe Post
# Fixjour example
subject_attributes { valid_post_attributes }

describe :published => true do
  it "should have default subject attributes" do
    subject_attributes.should == { :title => 'My title', :published => true }
  end
end
end
