Reorganize autoloads:
* A new module (ActiveSupport::Autoload) is provide that extends
autoloading with new behavior.
* All autoloads in modules that have extended ActiveSupport::Autoload
will be eagerly required in threadsafe environments
* Autoloads can optionally leave off the path if the path is the same
as full_constant_name.underscore
* It is possible to specify that a group of autoloads live under an
additional path. For instance, all of ActionDispatch's middlewares
are ActionDispatch::MiddlewareName, but they live under
"action_dispatch/middlewares/middleware_name"
* It is possible to specify that a group of autoloads are all found
at the same path. For instance, a number of exceptions might all
be declared there.
* One consequence of this is that testing-related constants are not
autoloaded. To get the testing helpers for a given component,
require "component_name/test_case". For instance, "action_controller/test_case".
* test_help.rb, which is automatically required by a Rails application's
test helper, requires the test_case.rb for all active components, so
this change will not be disruptive in existing or new applications.

Functional tests allow you to - # test a single controller action per test method. This should not be confused with - # integration tests (see ActionController::IntegrationTest), which are more like - # "stories" that can involve multiple controllers and mutliple actions (i.e. multiple - # different HTTP requests). - # - # == Basic example - # - # Functional tests are written as follows: - # 1. First, one uses the +get+, +post+, +put+, +delete+ or +head+ method to simulate - # an HTTP request. - # 2. Then, one asserts whether the current state is as expected. "State" can be anything: - # the controller's HTTP response, the database contents, etc. - # - # For example: - # - # class BooksControllerTest < ActionController::TestCase - # def test_create - # # Simulate a POST response with the given HTTP parameters. - # post(:create, :book => { :title => "Love Hina" }) - # - # # Assert that the controller tried to redirect us to - # # the created book's URI. - # assert_response :found - # - # # Assert that the controller really put the book in the database. - # assert_not_nil Book.find_by_title("Love Hina") - # end - # end - # - # == Special instance variables - # - # ActionController::TestCase will also automatically provide the following instance - # variables for use in the tests: - # - # <b>@controller</b>:: - # The controller instance that will be tested. - # <b>@request</b>:: - # An ActionController::TestRequest, representing the current HTTP - # request. You can modify this object before sending the HTTP request. For example, - # you might want to set some session properties before sending a GET request. - # <b>@response</b>:: - # An ActionController::TestResponse object, representing the response - # of the last HTTP response. In the above example, <tt>@response</tt> becomes valid - # after calling +post+. If the various assert methods are not sufficient, then you - # may use this object to inspect the HTTP response in detail. - # - # (Earlier versions of Rails required each functional test to subclass - # Test::Unit::TestCase and define @controller, @request, @response in +setup+.) - # - # == Controller is automatically inferred - # - # ActionController::TestCase will automatically infer the controller under test - # from the test class name. If the controller cannot be inferred from the test - # class name, you can explicitly set it with +tests+. - # - # class SpecialEdgeCaseWidgetsControllerTest < ActionController::TestCase - # tests WidgetController - # end - # - # == Testing controller internals - # - # In addition to these specific assertions, you also have easy access to various collections that the regular test/unit assertions - # can be used against. These collections are: - # - # * assigns: Instance variables assigned in the action that are available for the view. - # * session: Objects being saved in the session. - # * flash: The flash objects currently in the session. - # * cookies: Cookies being sent to the user on this request. - # - # These collections can be used just like any other hash: - # - # assert_not_nil assigns(:person) # makes sure that a @person instance variable was set - # assert_equal "Dave", cookies[:name] # makes sure that a cookie called :name was set as "Dave" - # assert flash.empty? # makes sure that there's nothing in the flash - # - # For historic reasons, the assigns hash uses string-based keys. So assigns[:person] won't work, but assigns["person"] will. To - # appease our yearning for symbols, though, an alternative accessor has been devised using a method call instead of index referencing. - # So assigns(:person) will work just like assigns["person"], but again, assigns[:person] will not work. - # - # On top of the collections, you have the complete url that a given action redirected to available in redirect_to_url. - # - # For redirects within the same controller, you can even call follow_redirect and the redirect will be followed, triggering another - # action call which can then be asserted against. - # - # == Manipulating the request collections - # - # The collections described above link to the response, so you can test if what the actions were expected to do happened. But - # sometimes you also want to manipulate these collections in the incoming request. This is really only relevant for sessions - # and cookies, though. For sessions, you just do: - # - # @request.session[:key] = "value" - # @request.cookies["key"] = "value" - # - # == Testing named routes - # - # If you're using named routes, they can be easily tested using the original named routes' methods straight in the test case. - # Example: - # - # assert_redirected_to page_url(:title => 'foo') - class TestCase < ActiveSupport::TestCase - include TestProcess - - # Executes a request simulating GET HTTP method and set/volley the response - def get(action, parameters = nil, session = nil, flash = nil) - process(action, parameters, session, flash, "GET") - end - - # Executes a request simulating POST HTTP method and set/volley the response - def post(action, parameters = nil, session = nil, flash = nil) - process(action, parameters, session, flash, "POST") - end - - # Executes a request simulating PUT HTTP method and set/volley the response - def put(action, parameters = nil, session = nil, flash = nil) - process(action, parameters, session, flash, "PUT") - end - - # Executes a request simulating DELETE HTTP method and set/volley the response - def delete(action, parameters = nil, session = nil, flash = nil) - process(action, parameters, session, flash, "DELETE") - end - - # Executes a request simulating HEAD HTTP method and set/volley the response - def head(action, parameters = nil, session = nil, flash = nil) - process(action, parameters, session, flash, "HEAD") - end - - def xml_http_request(request_method, action, parameters = nil, session = nil, flash = nil) - @request.env['HTTP_X_REQUESTED_WITH'] = 'XMLHttpRequest' - @request.env['HTTP_ACCEPT'] ||= [Mime::JS, Mime::HTML, Mime::XML, 'text/xml', Mime::ALL].join(', ') - returning __send__(request_method, action, parameters, session, flash) do - @request.env.delete 'HTTP_X_REQUESTED_WITH' - @request.env.delete 'HTTP_ACCEPT' - end - end - alias xhr :xml_http_request - - def process(action, parameters = nil, session = nil, flash = nil, http_method = 'GET') - # Sanity check for required instance variables so we can give an - # understandable error message. - %w(@controller @request @response).each do |iv_name| - if !(instance_variable_names.include?(iv_name) || instance_variable_names.include?(iv_name.to_sym)) || instance_variable_get(iv_name).nil? - raise "#{iv_name} is nil: make sure you set it in your test's setup method." - end - end - - @request.recycle! - @response.recycle! - @controller.response_body = nil - @controller.formats = nil - @controller.params = nil - - @html_document = nil - @request.env['REQUEST_METHOD'] = http_method - - parameters ||= {} - @request.assign_parameters(@controller.class.name.underscore.sub(/_controller$/, ''), action.to_s, parameters) - - @request.session = ActionController::TestSession.new(session) unless session.nil? - @request.session["flash"] = ActionController::Flash::FlashHash.new.update(flash) if flash - - @controller.request = @request - @controller.params.merge!(parameters) - build_request_uri(action, parameters) - Base.class_eval { include Testing } - @controller.process_with_new_base_test(@request, @response) - @response - end - - include ActionDispatch::Assertions - - # When the request.remote_addr remains the default for testing, which is 0.0.0.0, the exception is simply raised inline - # (bystepping the regular exception handling from rescue_action).
