here's /spec/requests/user_pages_spec.rb

require 'spec_helper'  describe "user pages"  subject { page }  describe "profile page" let(:user) { factorygirl.create(:user) } before { visit user_path(user) }  { should have_selector('h1', text: user.name) } { should have_selector('title', text: user.name) } end  describe "signup page" before { visit signup_path }  { should have_selector('h1', text: 'sign up') } { should have_selector('title', text: full_title('sign up')) } end  describe "signup"  before { visit signup_path }  describe "with invalid information"   "should not create user"     expect { click_button "create account" }.not_to change(user, :count)   end    describe "error messages"     before { click_button "create account" }      { should have_selector('title', text: 'sign up') }     { should have_content('error') }   end end    describe "with valid information"   before     fill_in "name", with: "example user"     fill_in "email", with: "user@example.com"     fill_in "password", with: "foobar"     fill_in "confirmation", with: "foobar"   end    "should create user"     expect       click_button "create account"     end.to change(user, :count).by(1)   end    describe "after saving user"     before { click_button "create account" }     let(:user) { user.find_by_email('user@example.com') }      { should have_selector('title', text: user.name) }     { should have_selector('div.alert.alert-success', text: 'welcome') }     { should have_link('sign out') }    end  end end  describe "signup page" before { visit signup_path }  { should have_selector('h1', text: 'sign up') } { should have_selector('title', text: full_title('sign up')) } end      describe "signup"  before { visit signup_path }  let(:submit) { "create account" }  describe "with invalid information"   "should not create user"     expect { click_button submit }.not_to change(user, :count)   end end  describe "with valid information"   before     fill_in "name", with: "example user"     fill_in "email", with: "user@example.com"     fill_in "password", with: "foobar"     fill_in "confirmation", with: "foobar"   end    "should create user"     expect { click_button submit }.to change(user, :count).by(1)   end   describe "edit"     let(:user) { factorygirl.create(:user) }     before { visit edit_user_path(user) }      describe "page"       { should have_selector('h1', text: "update profile") }       { should have_selector('title', text: "edit user") }       { should have_link('change', href: 'http://gravatar.com/emails') }     end      describe "with invalid information"       before { click_button "save changes" }        { should have_content('error') }       end     end    end  end end

any ideas?

users_controller.rb

class userscontroller < applicationcontroller  def show @user = user.find(params[:id]) end  def new @user = user.new end  def create @user = user.new(params[:user]) if @user.save   sign_in @user   flash[:success] = "welcome sample app!"   redirect_to @user else   render 'new'    end  end end

your problem seems don't have edit action. add this

def edit     @user = user.find(params[:id]) end

to users controller.
