You need to put those test methods into a Test::Unit::TestCase...
Hi,
I am trying to pull together a unit testing for routes but I am
getting confused. I have read AWDWR section 21.4 which explains how
to code the assertions. Testing Rails Applications — Ruby on Rails Guides
also basically says the same. The problem I have is working out what
else I need in my test/unit/test_routing.rb.
Change the file name from test_routing.rb to routing_test.rb (the rake task to run the tests is probably looking for *_test.rb). Your specific run of the file with ruby is actually fine, however.
I typically put these into test/functional/..._test.rb because they relate to controllers (and functional tests are really "unit tests for controllers").
require File.dirname(__FILE__) + '/../test_helper'
class RoutingTest < Test::Unit::TestCase
def test_recognizes
ActionController::Routing.use_controllers! ["quote"]
load "config/routes.rb"
test "internal routing" do
assert_recognizes({"controller" => "quote" , "action" =>
"index" }, "/quote" )
assert_recognizes({"controller" => "quote" , "action" =>
"new" }, "/" )
end
end
# get rid of this do-nothing test
def test_routing
true
end
end
The output is the following:
$ ruby -I development test/unit/routing_test.rb
Loaded suite test/unit/routing_test
Started
Finished in 0.000182 seconds.
0 tests, 0 assertions, 0 failures, 0 errors
Agreed it is super fast, but there appears to be no testing going on.
It's early days on my testing on Rails so I am sure I am missing
something major here. Thanks for any pointers in the right direction.
O.
I would similarly avoid testing more than one route per test. I tend to only bother with routing tests when they relate to AJAX callbacks or otherwise represent literal URL strings in JavaScript. Your tests seem to be verifying that you are using Rails routing properly -- not that it is wrong, but it should be more for your learning that a habit that you continue once you understand how to create routes.
Here's some actual code from the test/functional/similarity_controller_test.rb on one of my projects (but only some parts that are testing routes). (And be aware that this project is *OLD* as in Rails 1.2.6 so investigate how to do the same thing in your particular version of Rails. In particular, I know that setup is completely different in Rails 2.x.)
require File.dirname(__FILE__) + '/../test_helper'
require 'similarity_controller'
# Re-raise errors caught by the controller.
class SimilarityController; def rescue_action(e) raise e end; end
class SimilarityControllerTest < Test::Unit::TestCase
fixtures :users, :categories, :products
def setup
@controller = SimilarityController.new
@request = ActionController::TestRequest.new
@response = ActionController::TestResponse.new
end
def test__controller_naming
assert_equal('similarity', @controller.controller_name,
"None of the routing tests will work if controller_name is not 'similarity'")
end
# vendor/rails/actionpack/lib/action_controller/assertions/routing_assertions.rb
def test__route_similarity_categories
assert_routing '/similarity', { :controller => 'similarity', :action => 'categories' }
end
def test__route_similarity_trait_groups
assert_routing '/similarity/1/groups', { :controller => 'similarity', :action => 'trait_groups', :id => '1' }
end
def test__route_similarity_candidates
assert_routing('/similarity/1/group/2',
{ :controller => 'similarity', :action => 'list',
:id => '1', :trait_group => '2' })
end
#....
# Need to split these out in order to require that POST is used.
def test__route_similarity_make_similar
assert_recognizes({ :controller => 'similarity', :action => 'make_similar',
:id => '1', :trait_group => '2', :leader => '3', :follower => '4' },
{ :path => '/similarity/1/group/2/3/4', :method => :post })
assert_generates('/similarity/1/group/2/3/4',
{ :controller => 'similarity', :action => 'make_similar',
:id => '1', :trait_group => '2', :leader => '3', :follower => '4' })
end
# Need to split these out in order to require that DELETE is used.
def test__route_similarity_remove
assert_recognizes({ :controller => 'similarity', :action => 'remove',
:id => '1', :trait_group => '2', :follower => '4' },
{ :path => '/similarity/1/group/2/remove/4', :method => :delete })
assert_generates('/similarity/1/group/2/remove/4',
{ :controller => 'similarity', :action => 'remove',
:id => '1', :trait_group => '2', :follower => '4' })
end
#....
end
I hope that helps you.
