Each YAML fixture (ie. record) is given a name and # is followed by an indented list of key/value pairs in the "key: value" format. Records are # separated by a blank line for your viewing pleasure. # # Note: Fixtures are unordered. If you want ordered fixtures, use the omap YAML type. # See http://yaml.org/type/omap.html # for the specification. You will need ordered fixtures when you have foreign key constraints # on keys in the same table. This is commonly needed for tree structures. Example: # # --- !omap # - parent: # id: 1 # parent_id: NULL # title: Parent # - child: # id: 2 # parent_id: 1 # title: Child # # = Using Fixtures in Test Cases # # Since fixtures are a testing construct, we use them in our unit and functional tests. 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, +test_helper.rb+ will load all of your fixtures into your test # database, so this test will succeed. # # The testing environment will automatically load all the 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. # # Passing in a fixture name to this dynamic method returns the fixture matching this name: # # test "find one" do # assert_equal "Ruby on Rails", web_sites(:rubyonrails).name # end # # Passing in multiple fixture names returns all fixtures matching these names: # # test "find all by name" do # assert_equal 2, web_sites(:rubyonrails, :google).length # end # # Passing in no arguments returns all fixtures: # # test "find all" do # assert_equal 2, web_sites.length # end # # Passing in any fixture name that does not exist will raise StandardError: # # test "find by name that does not exist" do # assert_raise(StandardError) { web_sites(:reddit) } # 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.name # end # # In order to use these methods to access fixtured data within your test cases, you must specify one of the # following in your ActiveSupport::TestCase-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 # # Sometimes 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: # # <% 1.upto(1000) do |i| %> # fix_<%= i %>: # id: <%= i %> # name: guy_<%= i %> # <% end %> # # This will create 1000 very simple fixtures. # # Using ERB, you can also inject dynamic values into your fixtures with inserts like # <%= Date.today.strftime("%Y-%m-%d") %>. # 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. # # Helper methods defined in a fixture will not be available in other fixtures, to prevent against # unwanted inter-test dependencies. Methods used by multiple fixtures should be defined in a module # that is included in ActiveRecord::FixtureSet.context_class. # # - define a helper method in `test_helper.rb` # module FixtureFileHelpers # def file_sha(path) # Digest::SHA2.hexdigest(File.read(Rails.root.join('test/fixtures', path))) # end # end # ActiveRecord::FixtureSet.context_class.include FixtureFileHelpers # # - use the helper method in a fixture # photo: # name: kitten.png # sha: <%= file_sha 'files/kitten.png' %> # # = Transactional Tests # # Test cases 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_tests = 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 rake task) and use # transactional tests, 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 tests: # # 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 Fixtures # # 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 # # There are some more advanced features available even if the id is specified: # # * 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. Let's # use labels instead of IDs: # # ### in pirates.yml # # reginald: # name: Reginald the Pirate # monkey: george # # ### in monkeys.yml # # george: # name: George the Monkey # pirate: reginald # # Pow! 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* (monkey_id: 1). # # ==== 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 Time.now. # # 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 # email: $LABEL@email.com # # 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. ERB # to the rescue: # # george_reginald: # monkey_id: <%= ActiveRecord::FixtureSet.identify(:reginald) %> # pirate_id: <%= ActiveRecord::FixtureSet.identify(:george) %> # # == Support for YAML defaults # # You can set and reuse defaults in your fixtures YAML file. # This is the same technique used in the +database.yml+ file to specify # defaults: # # DEFAULTS: &DEFAULTS # created_on: <%= 3.weeks.ago.to_s(:db) %> # # first: # name: Smurf # <<: *DEFAULTS # # second: # name: Fraggle # <<: *DEFAULTS # # Any fixture labeled "DEFAULTS" is safely ignored. # # == Configure the fixture model class # # It's possible to set the fixture's model class directly in the YAML file. # This is helpful when fixtures are loaded outside tests and # +set_fixture_class+ is not available (e.g. # when running rails db:fixtures:load). # # _fixture: # model_class: User # david: # name: David # # Any fixtures labeled "_fixture" are safely ignored. class FixtureSet #-- # An instance of FixtureSet is normally stored in a single YAML file and # possibly in a folder with the same name. #++ MAX_ID = 2**30 - 1 @@all_cached_fixtures = Hash.new { |h, k| h[k] = {} } def self.default_fixture_model_name(fixture_set_name, config = ActiveRecord::Base) # :nodoc: config.pluralize_table_names ?
