Webrat is a browser simulator. With RSpec and Webrat you can write integration tests and test the UI of your Web App!
Assume you have a Web App with Ruby on Rails and you want to test your Landing Page. So that you ensure that some elements are for sure there. You could write a RSpec for that. Here is an example.
require 'spec_helper' describe "landing page" do it "diplays the landing page" do get "/" assert_response :success assert_select "form[action=?]", "/search" assert_select "input[name=?]", "q" assert_select "body div.container section" assert_select "h1", 2 end end
With “get /” you are basicly sending a request to the landing page. In the next line you just expect that you get a page successful back, without any HTTP 404 or 505 erors! In the next lines you ensure that there is a form on the landing page and the action of the form shows to “/search”. Further on you ensure that the input name in the form is “q”. And you ensure that there are 2 Header with h1 on the landing page.
If something of that is missing the test / spec will fail.
You can do much more with RSpec. This was just a small example. Check out the original page: http://rspec.info/
