嵌套资源测试RSpec的

Question

我有两个型号：

class Solution < ActiveRecord::Base 
    belongs_to :owner, :class_name => "User", :foreign_key => :user_id 
end     

class User < ActiveRecord::Base 
    has_many :solutions 
end 

与以下路由：

map.resources :users, :has_many => :solutions 

这里是SolutionsController：

class SolutionsController < ApplicationController 
    before_filter :load_user 

    def index 
    @solutions = @user.solutions 
    end 

    private 
    def load_user 
     @user = User.find(params[:user_id]) unless params[:user_id].nil? 
    end 
end 

任何人可以帮助我写作索引行动的测试？到目前为止，我曾尝试以下，但它不工作：

describe SolutionsController do 
    before(:each) do 
    @user = Factory.create(:user) 
    @solutions = 7.times{Factory.build(:solution, :owner => @user)} 
    @user.stub!(:solutions).and_return(@solutions) 
    end 

    it "should find all of the solutions owned by a user" do 
    @user.should_receive(:solutions) 
    get :index, :user_id => @user.id 
    end 
end 

而且我得到以下错误：

Spec::Mocks::MockExpectationError in 'SolutionsController GET index, when the user owns the software he is viewing should find all of the solutions owned by a user' 
#<User:0x000000041c53e0> expected :solutions with (any args) once, but received it 0 times 

预先感谢所有帮助。

编辑：

感谢您的回答，我接受它，因为它得到了我这么多的更远，除了我得到另一个错误，而我不能完全弄清楚它的努力告诉我：

一旦我创建了解决方案，而不是建立他们，我添加了User.find的存根，我看到以下错误：

NoMethodError in 'SolutionsController GET index, when the user owns the software he is viewing should find all of the solutions owned by a user' 
undefined method `find' for #<Class:0x000000027e3668>  

Answer 1

这是因为... e您构建解决方案，而不是创建。所以没有在你的数据库中。

制造

before(:each) do 
    @user = Factory.create(:user) 
    @solutions = 7.times{Factory.create(:solution, :owner => @user)} 
    @user.stub!(:solutions).and_return(@solutions) 
    end 

你嘲笑的用户实例，但也有用户的另一个实例可以实例化。您需要添加模拟User.find太

before(:each) do 
    @user = Factory.create(:user) 
    @solutions = 7.times{Factory.create(:solution, :owner => @user)} 
    User.stub!(:find).with(@user.id).and_return(@user) 
    @user.stub!(:solutions).and_return(@solutions) 
    end 

Answer 2

我想通了，我的编辑，当发现从PARAMS做，他们，而不是实际的对象或整数串，所以不是：

User.stub!(:find).with(@user.id).and_return(@user) 

我需要

User.stub!(:find).with(@user.id.to_s).and_return(@user) 

但谢谢你，你让我在正确的方向这么多shingara！
