Helper for testing default routes generated by a resource in Ruby on Rails

grantneufeld (Grant Neufeld) — Mon, 10 Sep 2007 12:46:23 GMT

These methods test that the routes for resources defined in routes.rb are working as expected. Call them from your functional (controller) tests.

Add the following 3 methods to test/test_helper.rb (updated for Rails 1.2.5 which no longer uses semicolons as a separator for the edit action):



# Test for routes generated by map.resource (singular).

def assert_routing_for_resource(controller, skip=[], nesting=[])

  routes = [

    ["new",'/new',{},:get], ["create",'',{},:post],

    ["show",'',{},:get], ["edit",'/edit',{},:get],

    ["update",'',{},:put], ["destroy",'',{},:delete]

    ]

  check_resource_routing(controller, routes, skip, nesting)

end

# Test for routes generated by map.resources (plural).

def assert_routing_for_resources(controller, skip=[], nesting=[])

  routes = [

    ["index",'',{},:get], ["new",'/new',{},:get], ["create",'',{},:post],

    ["show",'/1',{:id=>'1'},:get], ["edit",'/1/edit',{:id=>'1'},:get],

    ["update",'/1',{:id=>'1'},:put], ["destroy",'/1',{:id=>'1'},:delete]

    ]

  check_resource_routing(controller, routes, skip, nesting)

end



# Check that the expected paths will be generated by a resource, and that

# the expected params will be generated by paths defined by a resource.

# routes is array of [action, url string after controller, extra params].

def check_resource_routing(controller, routes, skip=[], nesting=[])

  # set a prefix for nested resources

  prefix = nesting.join('s/1/')

  unless prefix.blank?

    prefix += "s/1/"

  end

  # Add params for nested resources.

  # For each 'nest', include a ":nest_id=>'1'" param.

  params = {}

  nesting.each do |param|

    params["#{param}_id".to_sym] = '1'

  end

  # Test each of the standard resource routes.

  routes.each do |pair|

    unless skip.include? pair[0]

      assert_generates("/#{prefix}#{controller}#{pair[1]}",

        {:controller=>controller,

        :action=>pair[0]}.merge(pair[2]).merge(params), {}, {},

        "Failed generation of resource route for action #{pair[0]} /#{prefix}#{controller}#{pair[1]}")

      assert_recognizes(

        {:controller=>controller,

          :action=>pair[0]}.merge(pair[2]).merge(params),

        {:path=>"/#{prefix}#{controller}#{pair[1]}", :method=>pair[3]},

        {}, "Failed to recognize resource route for path #{pair[3]}:/#{prefix}#{controller}#{pair[1]}")

    end

  end

end

EXAMPLES

You can specify actions to 'skip' (if you have a special route for that action).
If using nested resources, set the nesting array (use singular strings).

So, if you have the following in routes.rb:



map.make_thing '/make', :controller=>'things', :action=>'new'

map.resources :nests do |nest|

  nest.resources :things

end

map.resource :foo

then you can use the following in things_controller_test.rb:



def test_resource_routing

  assert_routing_for_resources 'things', ['new'], ['nest']

  assert_routing_for_resource 'foo'

end

# This code is a different approach to using Growl notifications (Mac OS X)
# with autotest for Ruby.
# The code can be added to ~/.autotest
# Be sure to comment out "require 'autotest/growl'" if you have that line
# in your .autotest file.
# Based on ZenTest-3.6.1/lib/autotest/growl.rb
# Requires the 2 rails png graphics found at:
# http://blog.internautdesign.com/2006/11/12/autotest-growl-goodness



module Autotest::Growl

  # save the name of the working directory (e.g., the app name)

  # to be used as a key to identify this particular run of autotest

  # so the same growl notification will be reused for updates,

  # instead of a new growl window for every posting.

  @@current_directory_name = Dir.pwd.match(/([^\/]+)\z/).to_s

  def self.growl title, msg, pri=0

    title += " in #{@@current_directory_name}"

    msg += " at #{Time.now}"

    # ### change the path to the directory for the png graphics:

    system "growlnotify -n autotest #{pri > 0 ? '-s ' : ''}--image /Users/grant/Pictures/rails_#{pri > 0 ? 'fail' : 'ok'}.png -p #{pri} -d '#{Dir.pwd}' -m #{msg.inspect} #{title}"

  end



  Autotest.add_hook :run do  |at|

    growl "autotest running", "Started"

  end

  Autotest.add_hook :red do |at|

    growl "Tests Failed", "#{at.files_to_test.size} tests failed", 2

  end

  Autotest.add_hook :green do |at|

    growl "Tests Passed", "Tests passed", -2 if at.tainted

  end

  Autotest.add_hook :all_good do |at|

    growl "Tests Passed", "All tests passed", -2 if at.tainted

  end
