require 'spec_helper'
describe "posts" do
before do
@topic = Forem::Topic.new(:subject => "First topic!")
@topic.posts.build(:text => "First post!")
@topic.save!
end
end
In order to reply to a topic, you’re going to need to create one. You initialize a new
Forem::Topic object by using Forem::Topic.new and then build a post for it. This
means that when you navigate to the topic’s page, then you’ll see a post that will have
a Reply link for you to click. You’ll put the test underneath the before by using the
code in the following listing.
Listing 17.10 spec/integration/posts_spec.rb
it "reply to a topic" do
visit topics_path
click_link "First topic!"
within ".forem_topic #posts .forem_post" do
click_link "Reply"
end
fill_in "Text", :with => "First reply!"
click_button "Create Post"
within "#flash_notice" do
page.should have_content("Post has been created!")
end
within ".forem_topic #posts .forem_post:last" do
page.should have_content("First reply!")
end
end
In this test, you go to topics_path and click the First Topic! link. Then within a post,
you click the Reply link, which will take you to the form to create a new reply to this
topic. On this new page, you fill in the text with a short message and click the Create
Post button to create a new post. Once this is done, you’ll be taken to the create
action in Forem::PostsController, which will set the flash[:notice] to be “Post has
been created!” and then redirect you back to the topic’s page, where you should see
First Reply! within a post.
You’ve used a slightly obscure selector syntax here; you’re looking for the
#forem_topic element, which contains a #posts element, which itself contains many
.forem_post elements, of which you want the last one B. This will indicate to you
that on the page, the post that has been created is now at the bottom of the posts listing
for this topic, right where it should be.
