Why are my RSpec tests failing, but my app is working?
I just finished chapter 10 of the Ruby on Rails Tutorial, adding the ability to edit/update, index, and destroy users. Everything appears to be working properly in my app, but many of my tests are failing when I run RSpec.
I have the users_controller_spec set up exactly as the book does it and my application code is the same as well. Could one issue may be that I am using Rails 3.1.1 as opposed to Rails 3.0 which he uses in the book? It hasn't really been an issue for previous tests, just occasionally for a few different lines of code. The issues started appearing after I started section 10.2.1.
Here is the list of errors that I am seeing and please let me know if you need more info. Thanks!

UPDATE:
I solved 2 of the errors, but most are still persisting. One issue appears to be that when the test is trying to "get :index", it's not finding the correct page because of a redirect (to the /signin page). I did not institute any redirects (on purpose anyway), but maybe someone has an idea of how this might have happened and how it could be fixed?
UPDATE #2:
Per @bkempner's request, here's the relevant code from the users_controller_spec and the users_controller (users_controller_spec first). Lot of code, but lot of errors...:
describe "for signed-in users" do
before(:each) do
@user = test_sign_in(Factory(:user))
second = Factory(:user, :email => "[email protected]")
third = Factory(:user, :email => "[email protected]")
@users = [@user, second, third]
30.times do
@users << Factory(:user, :email => Factory.next(:email))
end
end
it "should be successful" do
get :index
response.should be_success
end
it "should have the right title" do
get :index
response.should have_selector("title", :content => "All users")
end
it "should have an element for each user" do
get :index
@users[0..2].each do |user|
response.should have_selector("li", :content => user.name)
end
end
it "should paginate users" do
get :index
response.should have_selector("div.pagination")
response.should have_selector("span.diabled", :content => "Previous")
response.should have_selector("a", :href => "/users?page=2", :content => "2")
response.should have_selector("a", :href => "/users?page=2", :content => "Next")
end
end
describe "GET 'edit'" do
before(:each) do
@user = Factory(:user)
test_sign_in(@user)
end
it "should be successful" do
get :edit, :id => @user
response.should be_success
end
it "should have the right title" do

end

@attr = { :email => "", :name => "", :password => "", :password_confirmation => "" }
end
it "should render the 'edit' page" do
put :update, :id => @user, :user => @attr
response.should render_template('edit')
end
it "should have the right title" do
put :update, :id => @user, :user => @attr
response.should have_selector("title", :content => "Edit user")
end
end

@attr = { :name => "New Name", :email => "[email protected]", :password => "barbaz", :password_confirmation => "barbaz" }
end
it "should change the user's attributes" do
put :update, :id => @user, :user => @attr
@user.reload
@user.name.should == @attr[:name]
@user.email.should == @attr[:email]
end
it "should redirect to the user show page" do
put :update, :id => @user, :user => @attr
response.should redirect_to(user_path(@user))
end
it "should have a flash message" do
put :update, :id => @user, :user => @attr
flash[:success].should =~ /updated/
end
end
end
describe "authentication of edit/update pages" do
describe "for signed-in users" do
before(:each) do
wrong_user = Factory(:user, :email => "[email protected]")
test_sign_in(wrong_user)
end
it "should require matching users for 'edit'" do
get :edit, :id => @user
response.should redirect_to(root_path)
end
it "should require matching users for 'update'" do
get :update, :id => @user, :user => {}
response.should redirect_to(root_path)
end
end
end
describe "DELETE 'destroy'" do
before(:each) do
@user = Factory(:user)
end
describe "as a non-admin user" do
it "should protect the page" do
test_sign_in(@user)
delete :destroy, :id => @user
response.should redirect_to(root_path)
end
end
describe "as an admin user" do
before(:each) do
admin = Factory(:user, :email => "[email protected]", :admin => true)
test_sign_in(admin)
end
it "should destroy the user" do
lambda do
delete :destroy, :id => @user
end.should change(User, :count).by(-1)
end
it "should redirect to the users page" do
delete :destroy, :id => @user
response.should redirect_to(users_path)
end
end
end
And now the entire users_controller:
class UsersController < ApplicationController
before_filter :authenticate, :only => [:index, :edit, :update, :destroy]
before_filter :correct_user, :only => [:edit, :update]
before_filter :admin_user, :only => :destroy
def index
@title = "All users"
@users = User.paginate(:page => params[:page])
end
def show
@user = User.find(params[:id])
@title = @user.name
end
def new
@user = User.new
@title = "Sign up"
end
def create
@user = User.new(params[:user])
if @user.save
sign_in @user
flash[:success] = "Welcome to the Sample App!"
redirect_to @user
else
@title = "Sign up"
render 'new'
end
end
def edit
@title = "Edit user"
end
def update
@user = User.find(params[:id])
if @user.update_attributes(params[:user])
flash[:success] = "Profile updated"
redirect_to @user
else
@title = "Edit user"
render 'edit'
end
end
def destroy
User.find(params[:id]).destroy
flash[:success] = "User destroyed."
redirect_to users_path
end
private
def authenticate
deny_access unless signed_in?
end
def correct_user
@user = User.find(params[:id])
redirect_to(root_path) unless current_user?(@user)
end
def admin_user
redirect_to(root_path) unless current_user.admin?
end
end
Answer
I had the same issue and found the answer posted here.
basically RSPEC needs both @current_user and current user to be set for sign_in and sign_out. Weird and annoying, but perhaps the reason one might consider using Devise in a production app!
