Shoulda gets busy with your controllers
A while back we
released the Shoulda Plugin to
help with testing your ActiveRecord models. Well, we've been using it in more and more
of our projects, and we've just finished adding some super cool controller tests.
Check it out!
Controller Macros
Right off the bat, you get some pretty little test helpers:
class UsersControllerTest < Test::Unit::TestCase
context "on GET to :show for first record" do
setup do
get :show, :id => 1
end
should_assign_to :user
should_respond_with :success
should_render_template :show
should_not_set_the_flash
should "do something else really cool" do
assert_equal 1, assigns(:user).id
end
end
end
That bit of code makes five functional tests, and is super easy to read. To take it a
step further - if you've been a good boy and have kept to the latest restful standards
in your controllers, then you're in luck.
should_be_restful
You can produce an entire set of tests (over 40) for both html and xml formats through
the should_be_restful helper.
class UsersControllerTest < Test::Unit::TestCase
load_all_fixtures
def setup
@controller = UsersController.new
@request = ActionController::TestRequest.new
@response = ActionController::TestResponse.new
@user = User.find(:first)
end
should_be_restful do |resource|
resource.parent = :country
resource.create.params = { :name => "bob", :email => 'bob@bob.com', :age => 13}
resource.update.params = { :name => "sue" }
end
end
should_be_restful is very configurable, but as the name states, it's only
intended for testing restful controllers. We've finished tests for the HTML and XML
formats, and RSS, YAML, and JSON will soon be on their way.

documentation for more information and
examples.
