学习札记——Rspec+factory_girl进行复杂模型测试

class Node
belongs_to :parent,:class_name =>Node
has_many :children,:class_name =>Node
                :foreign_key =>:parent_id
end

FactoryGirl.define do
factory :node do
title “XXXXX”
factory :node_leaf ,:class => :node do

association :parent,:factory =>:node
end
end

FactoryGirl.define do
factory :node do
title “XXXXX”
factory :node_root,:class => :node do
after_create do |node|
node.children <<FactoryGirl.create(:node,:parent => node)
node.children <<FactoryGirl.create(:node,:parent => node)
node.children <<FactoryGirl.create(:node,:parent => node)
end
end
end
end

Factory.build(:node_root) #这种方式不会被保存在数据库中
Factory.create（:node_leaf）#这种方式其实就多了一个SAVE动作

Factory.create(:node_root).children.find_by_title(“1”)

Factory.create(:node_root).children.each do |node|

node.title
end
