您如何测试扩展ActiveSupport :: Concern的模块？
|
我有一个扩展ActiveSupport :: Concern的模块。这是“ 0”块：
included do
after_save :save_tags
has_many :taggings, :as => :taggable
has_many :tags, :through => :taggings
end
没有找到相关结果

关联和回调，则可以设置一个简单的rspec期望值：class Dummy end describe Taggable do it \"should setup active record associations when included into models\" do Dummy.should_receive(:has_many).twice Dummy.should_receive(:after_save).with(:save_tags) Dummy.send(:include, Taggable) # send is necessary because it\'s a private method end end方法，而无需进行进一步的模拟，但是如果您要测试依赖于has_many关联被设置的行为，则可以创建另一个具有has_many和after_save的Dummy类，但需要使用关联的访问器：class Dummy attr_accessor :taggings, :tags # stub out these two def self.has_many end def self.after_save end def initialize @taggings = [] @tags = [] end include Taggable end describe Taggable do it \"should provide a formatted list of tags, or something\" do d = Dummy.new d.tags = [double(\'tag\')] d.formatted_tags.size.should == 1 end endclass Dummy def self.has_many(plural_object_name, options={}) instance_var_sym = \"@#{plural_object_name}\".to_sym # Create the attr_reader, setting the instance var if it doesn\'t exist already define_method(plural_object_name) do instance_variable_get(instance_var_sym) || instance_variable_set(instance_var_sym, []) end # Create the attr_writer define_method(\"#{plural_object_name}=\") do |val| instance_variable_set(instance_var_sym, val) end end include Taskable end席酱
