Rails%203%20In%20Action

Classes outside your control
This includes Forem::TopicsController, where you just used it, and Forem::Posts-
Controller, where you are about to use it to ensure that users are signed in before
being able to create new posts.
Before you use this method, you’ll add a test to the spec/integration/posts_spec.rb
to check that a user cannot access the new action if they aren’t signed in, and it will fail
because you’re not using it yet.
You’re going to have two context blocks in your spec, one for unauthenticated
users and the other for authenticated users. You can share the before block between
these two contexts if you take the sign_in! method out and turn your spec into what’s
shown in the following listing.
Listing 17.17 spec/integration/posts_spec.rb
require 'spec_helper'
describe "posts" do
before do
@topic = Forem::Topic.new(:subject => "First topic!")
@topic.posts.build(:text => "First post!")
@topic.save!
end
context "unauthenticated users" do
before do
sign_out!
end
end
context "authenticated users" do
before do
sign_in!
end
it "reply to a topic" do
...
end
end
end
With the before block now run before both of your contexts, you’ll have the @topic
object available in both of them. In the “unauthenticated users” context block, you’ll
write your test for the unauthenticated new action access under the before block,
using the code from the following listing.
Listing 17.18 spec/integration/posts_spec.rb
it "cannot access the new action" do
visit new_topic_post_path(@topic)
page.current_url.should eql(sign_in_url)
end
