我无法理解为什么我似乎无法存根这个控制器方法 :load_user
,因为如果我将实际实现更改:load_user
为不返回和实例,我的所有测试都会失败@user
。
任何人都可以看到为什么controller.stub!(:load_user).and_return(@user)
当 RSpec 向控制器发出请求时,我的存根 () 似乎无法真正被调用?
require 'spec_helper'
describe TasksController do
before(:each) do
@user = Factory(:user)
sign_in @user
@task = Factory(:task)
User.stub_chain(:where, :first).and_return(@user)
controller.stub!(:load_user).and_return(@user)
end
#GET Index
describe "GET Index" do
before(:each) do
@tasks = 7.times{Factory(:task, :user => @user)}
@user.stub!(:tasks).and_return(@tasks)
end
it "should should find all of the tasks owned by a user" do
@user.should_receive(:tasks).and_return(@tasks)
get :index, :user_id => @user.id
end
it "should assign all of the user's tasks to the view" do
get :index, :user_id => @user.id
assigns[:tasks].should be(@tasks)
end
end
#GET New
describe "GET New" do
before(:each) do
@user.stub_chain(:tasks, :new).and_return(@task)

end

@task.should_receive(:save)
post :create, :user_id => @user.id, :task => @task
end

before(:each) do
@task.stub!(:save).and_return(true)
end
it "should set the flash[:notice] message to 'Task Added Successfully'"do
post :create, :user_id => @user.id, :task => @task
flash[:notice].should == "Task Added Successfully!"
end
it "should redirect to the user's task page" do
post :create, :user_id => @user.id, :task => @task
response.should redirect_to(user_tasks_path(@user.id))
end
end
context "when the task isn't saved successfully" do
before(:each) do
@task.stub(:save).and_return(false)
end
it "should return to the 'Create New Task' page do" do
post :create, :user_id => @user.id, :task => @task
response.should render_template('new')
end
end
end

context "when the tasks belong to the currently logged in user" do
it "should set the user instance variable to the currently logged in user" do
pending
end
end
context "when the tasks belong to another user" do
it "should set the flash[:notice] to 'Sorry but you can't view other people's tasks.'" do
pending
end
it "should redirect to the home page" do
pending
end
end
end
end
class TasksController < ApplicationController
before_filter :load_user
def index
@tasks = @user.tasks
end
def new
@task = @user.tasks.new
end
def create
@task = @user.tasks.new
if @task.save
flash[:notice] = "Task Added Successfully!"
redirect_to user_tasks_path(@user.id)
else
render :action => 'new'
end
end
private
def load_user
if current_user.id == params[:user_id].to_i
@user = User.where(:id => params[:user_id]).first
else
flash[:notice] = "Sorry but you can't view other people's tasks."
redirect_to root_path
end
end
end
谁能看到为什么我的存根不起作用?就像我说的,我的测试只有在我确保 load_user 工作时才能通过,如果没有,我的所有测试都会失败,这让我认为 RSpec 没有使用我创建的存根。
