Hey guys,

We developed this plugin while writing my first real set of RSpec
stories. It's still missing a lot of functionality, but it's useful to
us as is, so I'm shipping 0.1.0. (Patches welcome. :) )

Code is available at: http://svn.eastmedia.net/public/plugins/webrat/

What do you think?

= Webrat - Ruby Acceptance Testing for Web applications

by Bryan Helmkamp <bryan at brynary.com> and Seth Fitzsimmons <seth at mojodna.net>.

Initial development sponsored by EastMedia (http://www.eastmedia.com).

== DESCRIPTION:

Webrat lets you quickly write robust and thorough acceptance tests for a Ruby
web application. By leveraging the DOM, it can run tests similarly to an
in-browser testing solution without the associated performance hit (and
browser dependency). The result is tests that are less fragile and more
effective at verifying that the app will respond properly to users.

When comparing Webrat with an in-browser testing solution like Watir or
Selenium, the primary consideration should be how much JavaScript the
application uses. In-browser testing is currently the only way to test JS, and
that may make it a requirement for your project. If JavaScript is not central
to your application, Webrat is a simpler, effective solution that will let you
run your tests much faster and more frequently. (Benchmarks forthcoming.)

== SYNOPSIS:

  def test_sign_up
    visits "/"
    clicks_link "Sign up"
    fills_in "Email", :with => "good at example.com"
    select "Free account"
    clicks_button "Register"
    ...
  end

Behind the scenes, this will perform the following work:

1. Verify that loading the home page is successful
2. Verify that a "Sign up" link exists on the home page
3. Verify that loading the URL pointed to by the "Sign up" link leads to a
   successful page
4. Verify that there is an "Email" input field on the Sign Up page
5. Verify that there is an select field on the Sign Up page with an option for
   "Free account"
6. Verify that there is a "Register" submit button on the page
7. Verify that submitting the Sign Up form with the values "good at example.com"
   and "Free account" leads to a successful page

Take special note of the things _not_ specified in that test, that might cause
tests to break unnecessarily as your application evolves:

* The input field IDs or names (e.g. "user_email" or "user[email]"), which
  could change if you rename a model
* The ID of the form element (Webrat can do a good job of guessing, even if
  there are multiple forms on the page.)
* The URLs of links followed
* The URL the form submission should be sent to, which could change if you
  adjust your routes or controllers
* The HTTP method for the login request

A test written with Webrat can handle these changes smoothly.

== REQUIREMENTS:

* Rails >= 1.2.6
* Hpricot >= 0.6
* Rails integration tests in Test::Unit _or_
* RSpec stories (using an RSpec version >= revision 2997)

== INSTALL:

  $ ruby script/plugin install http://svn.eastmedia.net/public/plugins/webrat/
