简单的RSpec测试失败

Question

I'm following this tutorial here, and everything has worked out very well so far.

But now that I've progressed to sessions, some simple rspec tests are failing:

describe SessionsController do

  #[...]

  describe "GET 'new'" do

    it "should have the right title" do
      get :new
      response.should have_selector( "title", :content => "Sign in" )
    end

  end

  #[...]

  describe "POST 'create'" do

    #[...]

    it "should have the right title" do
      post :create, :session => @attr
      response.should have_selector("title", :content => "Sign in")
    end

    #[...]
  end

end

When I run rspec, I always get:

1) SessionsController GET 'new' should have the right title Failure/Error: response.should have_selector( "title", :content => "Sign in
) expected following output to contain a Sign in tag: w3.org/TR/REC-html40/loose.dtd"> # ./spec/controllers/sessions_controller_spec.rb:14:in `block (3 levels) in '

When I access the sessions/new page, the page contains a title tag like the following:

<title>Ruby on Rails Tutorial Sample App | Sign in</title> 

Why do those tests fail, while all other similar (= tests for the title tag) tests work fine?

Here's the SessionController:

class SessionsController < ApplicationController
  def new
    @title = 'Sign in'
  end

  def create

    user = User.authenticate( params[:session][:email], params[:session][:password] )

    if user.nil?
        flash.now[:error] = "Invalid email/password combination."
        @title = 'Sign in'
        render 'new'
    else
        sign_in user
        redirect_to user
    end
  end


    def destroy
        sign_out
        redirect_to root_path       
    end

end

What am I doing wrong here?

thx for your help

Answer 1

You need to add render_views to the top of the class. Without it, the actual html will not be generated and your have_selector tests will fail.
