title: Rails Tutorial Ch 12 exercise 2 - what to compare when Escaping HTML content
body: <p>just need a hint for this template</p>
  
  <pre><code>test "feed on Home page" do
    get root_path
      @user.feed.paginate(page: 1).each do |micropost|
      assert_match CGI.escapeHTML(FILL_IN), FILL_IN
    end
  end
  </code></pre>
  
  <p>i inserted it with micropost.content but still not sure for the next param
  for this code:</p>
  
  <pre><code>assert_match CGI.escapeHTML(micropost.content), 'something?'
  </code></pre>
  
  <p>i still can`t figure it out what is something is. it should not be a micropost.content too right ? </p>
