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:
# 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
