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.

The point of fixtures are that they're -# stable units of predictable sample data.

The format of a fixture file looks + # like this: + # + # rubyonrails: + # id: 1 + # name: Ruby on Rails + # url: http://www.rubyonrails.org + # + # google: + # id: 2 + # name: Google + # url: http://www.google.com + # + # This fixture file includes two fixtures. 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 that 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, <tt>test_helper.rb</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: + # + # <% 1.upto(1000) do |i| %> + # fix_<%= i %>: + # id: <%= i %> + # name: guy_<%= 1 %> + # <% end %> + # + # This will create 1000 very simple 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 + # + # 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_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 rake 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.
