About Windmill

Windmill is a web testing tool for automating and debugging web applications. This library provides a wrapper for interfacing with the Windmill API from Ruby.

This Ruby gem provides a automatically generated wrapper layer around the Windmill API. It uses the commands.getControllerMethods call to discover the methods and provides a one to one mapping for them.


Install Windmill according to the instruction available on the website. For interfacing to it from Ruby you need to install the windmill gem.

$ sudo gem install windmill


To get up and running quickly, the first step is to start a Windmill session, for example one for Google.

$ windmill run_service firefox

This starts a Firefox instance with a Windmill IDE that goes to Google. From there it's possible to add steps manually to experiment with it. These steps can also be run from Ruby.

require 'rubygems'
require 'windmill'

# Connect to the Windmill API
session ="http://localhost:4444/windmill-jsonrpc/")

# Enter the test 'windmill testing framework' into the field named 'q'
session.type(:name => 'q', :text => 'windmill testing framework')

# You can also use stuff like the xpath matcher to find a button => "//button[.='Google Search']")

# It also provides all assertions
result = session.asserts.assertText(:name => 'q', :validator => 'windmill testing framework')

# result now contains a hash with some information on whether the assertion was succesful,
# when it was executed, etc. 
# {"result"     => true, 
#  "endtime"    => "2009-5-14T13:34:58.139Z",
#  "method"     => "asserts.assertValue",
#  "output"     => nil,
#  "version"    => "0.1",
#  "suite_name" => nil,
#  "params"     => { "name"     => "q",
#                    "validator"=> "windmill testing framework",
#                    "uuid"=>"62704eec-58d7-11de-9509-001b639adff4"},
