model_stubbing ============== Creates in-memory versions of models for testing. This attempts to solve a few problems with ActiveRecord Fixtures: Speed - There's no hit to the database and no cleanup between tests. Flexibility - You can define a global set of stubs, or define custom ones for specific tests/specs A lot of these ideas were taken from various approaches to fixtures and mocking that I've seen: fixture scenarios (http://errtheblog.com/post/7708) unit_record (http://www.dcmanges.com/blog/rails-unit-record-test-without-the-database) Rspec and #mock_model Exemplar (http://www.bofh.org.uk/articles/2007/08/05/doing-the-fixture-thing) I actually saw Exemplar after I wrote the initial version, but they do seem similar. I honestly don't know if this is a better way or anything, I'm just experimenting with a different approach. Oh, and apparently this is an implementation of the ObjectMother (http://www.martinfowler.com/bliki/ObjectMother.html) pattern? # test/unit example # test/unit support not fully implemented yet require 'model_stubbing' class FooTest < Test::Unit::TestCase define_models do time 2007, 6, 1 model Role do stub :owner, :name => 'owner' stub :author, :name => 'author' end model User do stub :name => 'bob', :admin => false stub :admin, :admin => true # inherits from default fixture stub :author, :roles => [all_stubs(:author_role)] stub :owner, :roles => [all_stubs(:author_role), all_stubs(:owner_role)] end model Post do # uses admin user fixture above stub :title => 'initial', :user => all_stubs(:admin_user), :published_at => current_time + 5.days end end def test_foo @user = users(:default) # default user stub @admin = users(:admin) @custom = users(:default, :age => 25) # custom attributes, #but not equal to @user any more @post = posts(:default) @post.user # equal to @admin above current_time # stubbed to be 6/1/2007 using mocha or rspec end end # rspec example require 'model_stubbing' describe Foo do ... end TODO ==== * Support other mocking frameworks besides rspec and mocha? * Support Sequel, DataMapper, etc? I use AR, but I'm willing to abstract some of that out in case someone wants to support another ORM.
