Stubbing a before_filter with RSpec
- by TheDelChop
Guys,
I'm having trouble understanding why I can't seem to stub this controller method :load_user, since all of my tests fail if I change the actual implementation of :load_user to not return and instance of @user.
Can anybody see why my stub (controller.stub!(:load_user).and_return(@user)) seems to fail to actually get called when RSpec makes a request to the controller?
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
it "should return a new Task" do
@user.tasks.should_receive(:new).and_return(@task)
get :new, :user_id = @user.id
end
end
#POST Create
describe "POST Create" do
before(:each) do
@user.stub_chain(:tasks, :new).and_return(@task)
end
it "should create a new task" do
@user.tasks.should_receive(:new).and_return(@task)
post :create, :user_id = @user.id, :task = @task.to_s
end
it "saves the task" do
@task.should_receive(:save)
post :create, :user_id = @user.id, :task = @task
end
context "when the task is saved successfully" do
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
it "should attempt to authenticate and load the user who owns the tasks" do
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
Can anybody see why my stub doesnt' work? Like I said, my tests only pass if I make sure that load_user works, if not, all my tests fail which makes my think that RSpec isn't using the stub I created.
Thanks,
Joe
