There are two ways to use the -# fixtures, but first let's take a look at a sample unit test: -# -# require 'test_helper' -# -# class WebSiteTest < ActiveSupport::TestCase -# test "web_site_count" do -# assert_equal 2, WebSite.count -# end -# end -# -# By default, the <tt>test_helper module</tt> will load all of your fixtures into your test database, -# so this test will succeed. -# The testing environment will automatically load the all fixtures into the database before each test. -# To ensure consistent data, the environment deletes the fixtures before running the load. -# -# In addition to being available in the database, the fixture's data may also be accessed by -# using a special dynamic method, which has the same name as the model, and accepts the -# name of the fixture to instantiate: -# -# test "find" do -# assert_equal "Ruby on Rails", web_sites(:rubyonrails).name -# end -# -# Alternatively, you may enable auto-instantiation of the fixture data. For instance, take the following tests: -# -# test "find_alt_method_1" do -# assert_equal "Ruby on Rails", @web_sites['rubyonrails']['name'] -# end -# -# test "find_alt_method_2" do -# assert_equal "Ruby on Rails", @rubyonrails.news -# end -# -# In order to use these methods to access fixtured data within your testcases, you must specify one of the -# following in your <tt>ActiveSupport::TestCase</tt>-derived class: -# -# - to fully enable instantiated fixtures (enable alternate methods #1 and #2 above) -# self.use_instantiated_fixtures = true -# -# - create only the hash for the fixtures, do not 'find' each instance (enable alternate method #1 only) -# self.use_instantiated_fixtures = :no_instances -# -# Using either of these alternate methods incurs a performance hit, as the fixtured data must be fully -# traversed in the database to create the fixture hash and/or instance variables. This is expensive for -# large sets of fixtured data. -# -# = Dynamic fixtures with ERB -# -# Some times you don't care about the content of the fixtures as much as you care about the volume. In these cases, you can -# mix ERB in with your YAML fixtures to create a bunch of fixtures for load testing, like: -# -# <% for i in 1..1000 %> -# fix_<%= i %>: -# id: <%= i %> -# name: guy_<%= 1 %> -# <% end %> -# -# This will create 1000 very simple YAML fixtures. -# -# Using ERB, you can also inject dynamic values into your fixtures with inserts like <tt><%= Date.today.strftime("%Y-%m-%d") %></tt>. -# This is however a feature to be used with some caution. The point of fixtures are that they're -# stable units of predictable sample data. If you feel that you need to inject dynamic values, then -# perhaps you should reexamine whether your application is properly testable. Hence, dynamic values -# in fixtures are to be considered a code smell. -# -# = Transactional fixtures -# -# TestCases can use begin+rollback to isolate their changes to the database instead of having to -# delete+insert for every test case. -# -# class FooTest < ActiveSupport::TestCase -# self.use_transactional_fixtures = true -# -# test "godzilla" do -# assert !Foo.all.empty? -# Foo.destroy_all -# assert Foo.all.empty? -# end -# -# test "godzilla aftermath" do -# assert !Foo.all.empty? -# end -# end -# -# If you preload your test database with all fixture data (probably in the Rakefile task) and use transactional fixtures, -# then you may omit all fixtures declarations in your test cases since all the data's already there -# and every case rolls back its changes. -# -# In order to use instantiated fixtures with preloaded data, set +self.pre_loaded_fixtures+ to true. This will provide -# access to fixture data for every table that has been loaded through fixtures (depending on the -# value of +use_instantiated_fixtures+) -# -# When *not* to use transactional fixtures: -# -# 1. You're testing whether a transaction works correctly. Nested transactions don't commit until -# all parent transactions commit, particularly, the fixtures transaction which is begun in setup -# and rolled back in teardown. Thus, you won't be able to verify -# the results of your transaction until Active Record supports nested transactions or savepoints (in progress). -# 2. Your database does not support transactions. Every Active Record database supports transactions except MySQL MyISAM. -# Use InnoDB, MaxDB, or NDB instead. -# -# = Advanced YAML Fixtures -# -# YAML fixtures that don't specify an ID get some extra features: -# -# * Stable, autogenerated IDs -# * Label references for associations (belongs_to, has_one, has_many) -# * HABTM associations as inline lists -# * Autofilled timestamp columns -# * Fixture label interpolation -# * Support for YAML defaults -# -# == Stable, autogenerated IDs -# -# Here, have a monkey fixture: -# -# george: -# id: 1 -# name: George the Monkey -# -# reginald: -# id: 2 -# name: Reginald the Pirate -# -# Each of these fixtures has two unique identifiers: one for the database -# and one for the humans. Why don't we generate the primary key instead? -# Hashing each fixture's label yields a consistent ID: -# -# george: # generated id: 503576764 -# name: George the Monkey -# -# reginald: # generated id: 324201669 -# name: Reginald the Pirate -# -# Active Record looks at the fixture's model class, discovers the correct -# primary key, and generates it right before inserting the fixture -# into the database. -# -# The generated ID for a given label is constant, so we can discover -# any fixture's ID without loading anything, as long as we know the label. -# -# == Label references for associations (belongs_to, has_one, has_many) -# -# Specifying foreign keys in fixtures can be very fragile, not to -# mention difficult to read. Since Active Record can figure out the ID of -# any fixture from its label, you can specify FK's by label instead of ID. -# -# === belongs_to -# -# Let's break out some more monkeys and pirates. -# -# ### in pirates.yml -# -# reginald: -# id: 1 -# name: Reginald the Pirate -# monkey_id: 1 -# -# ### in monkeys.yml -# -# george: -# id: 1 -# name: George the Monkey -# pirate_id: 1 -# -# Add a few more monkeys and pirates and break this into multiple files, -# and it gets pretty hard to keep track of what's going on.

All is made clear. Active Record reflects on the fixture's model class, -# finds all the +belongs_to+ associations, and allows you to specify -# a target *label* for the *association* (monkey: george) rather than -# a target *id* for the *FK* (<tt>monkey_id: 1</tt>). -# -# ==== Polymorphic belongs_to -# -# Supporting polymorphic relationships is a little bit more complicated, since -# Active Record needs to know what type your association is pointing at. Something -# like this should look familiar: -# -# ### in fruit.rb -# -# belongs_to :eater, :polymorphic => true -# -# ### in fruits.yml -# -# apple: -# id: 1 -# name: apple -# eater_id: 1 -# eater_type: Monkey -# -# Can we do better? You bet! -# -# apple: -# eater: george (Monkey) -# -# Just provide the polymorphic target type and Active Record will take care of the rest. -# -# === has_and_belongs_to_many -# -# Time to give our monkey some fruit. -# -# ### in monkeys.yml -# -# george: -# id: 1 -# name: George the Monkey -# -# ### in fruits.yml -# -# apple: -# id: 1 -# name: apple -# -# orange: -# id: 2 -# name: orange -# -# grape: -# id: 3 -# name: grape -# -# ### in fruits_monkeys.yml -# -# apple_george: -# fruit_id: 1 -# monkey_id: 1 -# -# orange_george: -# fruit_id: 2 -# monkey_id: 1 -# -# grape_george: -# fruit_id: 3 -# monkey_id: 1 -# -# Let's make the HABTM fixture go away. -# -# ### in monkeys.yml -# -# george: -# id: 1 -# name: George the Monkey -# fruits: apple, orange, grape -# -# ### in fruits.yml -# -# apple: -# name: apple -# -# orange: -# name: orange -# -# grape: -# name: grape -# -# Zap! No more fruits_monkeys.yml file. We've specified the list of fruits -# on George's fixture, but we could've just as easily specified a list -# of monkeys on each fruit. As with +belongs_to+, Active Record reflects on -# the fixture's model class and discovers the +has_and_belongs_to_many+ -# associations. -# -# == Autofilled timestamp columns -# -# If your table/model specifies any of Active Record's -# standard timestamp columns (+created_at+, +created_on+, +updated_at+, +updated_on+), -# they will automatically be set to <tt>Time.now</tt>. -# -# If you've set specific values, they'll be left alone. -# -# == Fixture label interpolation -# -# The label of the current fixture is always available as a column value: -# -# geeksomnia: -# name: Geeksomnia's Account -# subdomain: $LABEL -# -# Also, sometimes (like when porting older join table fixtures) you'll need -# to be able to get a hold of the identifier for a given label.
