module Test #:nodoc:
module Unit #:nodoc:
# 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 deviced 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"
#
# For cookies, you need to manually create the cookie, like this:
#
# @request.cookies["key"] = CGI::Cookie.new("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')

# * <tt>:parent</tt>: a hash. The node's parent must match the
# corresponding hash.
# * <tt>:child</tt>: a hash. At least one of the node's immediate children
# must meet the criteria described by the hash.
# * <tt>:ancestor</tt>: a hash. At least one of the node's ancestors must
# meet the criteria described by the hash.
# * <tt>:descendant</tt>: a hash. At least one of the node's descendants
# must meet the criteria described by the hash.
# * <tt>:sibling</tt>: a hash. At least one of the node's siblings must
# meet the criteria described by the hash.
# * <tt>:after</tt>: a hash. The node must be after any sibling meeting
# the criteria described by the hash, and at least one sibling must match.
# * <tt>:before</tt>: a hash. The node must be before any sibling meeting
# the criteria described by the hash, and at least one sibling must match.
# * <tt>:children</tt>: a hash, for counting children of a node. Accepts
# the keys:
# * <tt>:count</tt>: either a number or a range which must equal (or
# include) the number of children that match.
# * <tt>:less_than</tt>: the number of matching children must be less
# than this number.
# * <tt>:greater_than</tt>: the number of matching children must be
# greater than this number.
# * <tt>:only</tt>: another hash consisting of the keys to use
# to match on the children, and only matching children will be
# counted.
# * <tt>:content</tt>: the textual content of the node must match the
# given value. This will not match HTML tags in the body of a
# tag--only text.
#
# Conditions are matched using the following algorithm:
#
# * if the condition is a string, it must be a substring of the value.
# * if the condition is a regexp, it must match the value.
# * if the condition is a number, the value must match number.to_s.
# * if the condition is +true+, the value must not be +nil+.
# * if the condition is +false+ or +nil+, the value must be +nil+.

# == Around filters
#
# In addition to the individual before and after filters, it's also possible to specify that a single object should handle
# both the before and after call. That's especially useful when you need to keep state active between the before and after,
# such as the example of a benchmark filter below:
#
# class WeblogController < ActionController::Base
# around_filter BenchmarkingFilter.new
#
# # Before this action is performed, BenchmarkingFilter#before(controller) is executed
# def index
# Around filters wrap an action, executing code both before and after.
# They may be declared as method references, blocks, or objects responding
# to #filter or to both #before and #after.
#
# To use a method as an around_filter, pass a symbol naming the Ruby method.
# Yield (or block.call) within the method to run the action.
#
# around_filter :catch_exceptions
#
# private
# def catch_exceptions
# yield
# rescue => exception
# logger.debug "Caught exception! #{exception}"
# raise
# end
# # After this action has been performed, BenchmarkingFilter#after(controller) is executed
#
# To use a block as an around_filter, pass a block taking as args both
# the controller and the action block. You can't call yield directly from
# an around_filter block; explicitly call the action block instead:
#
# around_filter do |controller, action|
# logger.debug "before #{controller.action_name}"
# action.call
# logger.debug "after #{controller.action_name}"
# end
#
# To use a filter object with around_filter, pass an object responding
# to :filter or both :before and :after. With a filter method, yield to
# the block as above:
#
# around_filter BenchmarkingFilter
#
# class BenchmarkingFilter
# def initialize
# @runtime
# end
#
# def before
# start_timer
# end
#
# def after
# stop_timer
# report_result
# def self.filter(controller, &block)
# Benchmark.measure(&block)
# end
# end
#
# With before and after methods:
#
# around_filter Authorizer.new
#
# class Authorizer
# # This will run before the action. Returning false aborts the action.
# def before(controller)
# if user.authorized?
# return true
# else
# redirect_to login_url
# return false
# end
# end
#
# # This will run after the action if and only if before returned true.
# def after(controller)
# end
# end
#
# If the filter has before and after methods, the before method will be
# called before the action. If before returns false, the filter chain is
# halted and after will not be run. See Filter Chain Halting below for
# an example.
#
# == Filter chain skipping
#
# Some times its convenient to specify a filter chain in a superclass that'll hold true for the majority of the
# subclasses, but not necessarily all of them. The subclasses that behave in exception can then specify which filters
# they would like to be relieved of. Examples
# Declaring a filter on a base class conveniently applies to its subclasses,
# but sometimes a subclass should skip some of its superclass' filters:
#
# class ApplicationController < ActionController::Base
# before_filter :authenticate
# around_filter :catch_exceptions
# end
#
# class WeblogController < ApplicationController
# # will run the :authenticate filter
# # Will run the :authenticate and :catch_exceptions filters.
# end
#
# class SignupController < ApplicationController
# # will not run the :authenticate filter
# # Skip :authenticate, run :catch_exceptions.
# skip_before_filter :authenticate
# end
#
# class ProjectsController < ApplicationController
# # Skip :catch_exceptions, run :authenticate.
# skip_filter :catch_exceptions
# end
#
# class ClientsController < ApplicationController
# # Skip :catch_exceptions and :authenticate unless action is index.
# skip_filter :catch_exceptions, :authenticate, :except => :index
# end
#
# == Filter conditions
#
# Filters can be limited to run for only specific actions. This can be expressed either by listing the actions to
# exclude or the actions to include when executing the filter. Available conditions are +:only+ or +:except+, both
# of which accept an arbitrary number of method references. For example:
# Filters may be limited to specific actions by declaring the actions to
# include or exclude. Both options accept single actions (:only => :index)
# or arrays of actions (:except => [:foo, :bar]).
#
# class Journal < ActionController::Base
# # only require authentication if the current action is edit or delete
# before_filter :authorize, :only => [ :edit, :delete ]
#
# # Require authentication for edit and delete.
# before_filter :authorize, :only => [:edit, :delete]
#
# # Passing options to a filter with a block.
# around_filter(:except => :index) do |controller, action_block|
# results = Profiler.run(&action_block)
# controller.response.sub! "</body>", "#{results}</body>"
# end
#
# private
# def authorize
# # redirect to login unless authenticated
# # Redirect to login unless authenticated.
# end
# end
#
# When setting conditions on inline method (proc) filters the condition must come first and be placed in parentheses.
#
# class UserPreferences < ActionController::Base
# before_filter(:except => :new) { # some proc ... }
# # ...
# end
# == Filter Chain Halting
#
# <tt>before_filter</tt> and <tt>around_filter</tt> may halt the request
# before controller action is run. This is useful, for example, to deny
# access to unauthenticated users or to redirect from http to https.
# Simply return false from the filter or call render or redirect.
#
# Around filters halt the request unless the action block is called.
# Given these filters
# after_filter :after
# around_filter :around
# before_filter :before
#
# The filter chain will look like:
#
# ...
# . \
# . #around (code before yield)
# . . \
# . . #before (actual filter code is run)
# . . . \
# . . . execute controller action
# . . . /
# . . ...
# . . /
# . #around (code after yield)
# . /
# #after (actual filter code is run)
#
# If #around returns before yielding, only #after will be run. The #before
# filter and controller action will not be run. If #before returns false,
# the second half of #around and all of #after will still run but the
# action will not.
