Webrat - Ruby Acceptance Testing for Web applications


Webrat lets you quickly write expressive and robust acceptance tests for a Ruby web application.


  • Browser Simulator for expressive, high level acceptance testing without the performance hit and browser dependency of Selenium or Watir (See Webrat::Session)

  • Use the same API for Browser Simulator and real Selenium tests using Webrat::Selenium when necessary (eg. for testing AJAX interactions)

  • Supports multiple Ruby web frameworks: Rails, Merb and Sinatra

  • Supports popular test frameworks: RSpec, Cucumber, Test::Unit and Shoulda

  • Webrat::Matchers API for verifying rendered HTML using CSS, XPath, etc.


class SignupTest < ActionController::IntegrationTest

    visit home_path
    click_link "Sign up"
    fill_in "Email", :with => "[email protected]"
    select "Free account"
    click_button "Register"


Behind the scenes, Webrat will ensure:

  • If a link, form field or button is missing, the test will fail.

  • If a URL is invalid, the test will fail.

  • If a page load or form submission is unsuccessful, the test will fail.

Installing Nokogiri

Users of Debian Linux (e.g. Ubuntu) need to run:

sudo apt-get install libxslt1-dev libxml2-dev.

Otherwise the Nokogiri gem, which Webrat depends on, won’t install properly.

Install for Rails

To install the latest release as a gem:

sudo gem install webrat

To install the latest code as a plugin: (Note: This may be less stable than using a released version)

script/plugin install git://github.com/brynary/webrat.git

In your test_helper.rb or env.rb (for Cucumber) add:

require "webrat"

Webrat.configure do |config|
  config.mode = :rails

Install with Merb

Merb 1.0 has built-in, seamless Webrat support. Just start using methods from Webrat::Session in your specs.
