Fix `class_name` qualifier for association matchers so that if the
model being referenced is namespaced, the matcher will correctly resolve
the class before checking it against the association's `class_name`.
Take these models for instance:
module Models
class Friend < ActiveRecord::Base
end
class User < ActiveRecord::Base
has_many :friends, class_name: 'Friend'
end
end
Here, the `has_many` is referring to Models::Friend, not just Friend.
Previously in order to test the association, you had to write:
describe Models::User do
it { should have_many(:friends).class_name('Models::Friend') }
end
Now, `have_many` will attempt to resolve the string given to
`class_name` within the context of the namespace first before treating
it as a reference to a global constant. This means you can now write
this:
describe Models::User do
it { should have_many(:friends).class_name('Friend') }
end

README.md
shoulda-matchers 
shoulda-matchers provides Test::Unit- and RSpec-compatible one-liners that test common Rails functionality. These tests would otherwise be much longer, more complex, and error-prone.
ActiveModel Matchers
- allow_mass_assignment_of
tests usage of Rails 3's
attr_accessibleandattr_protectedmacros. - allow_value tests usage of
the
validates_format_ofvalidation. - validate_inclusion_of
tests usage of
validates_inclusion_of. - validate_exclusion_of
tests usage of
validates_exclusion_of. - validate_length_of tests usage
of
validates_length_of. - have_secure_password tests
usage of
has_secure_password. - validate_confirmation_of
tests usage of
validates_confirmation_of. - validate_numericality_of
tests usage of
validates_numericality_of. - validate_presence_of tests
usage of
validates_presence_of. - validate_uniqueness_of tests
usage of
validates_uniqueness_of.
ActiveRecord Matchers
- accept_nested_attributes_for
tests usage of the
accepts_nested_attributes_formacro. - belong_to tests
your
belongs_toassociations. - define_enum_for
tests usage of the
enummacro. - have_many tests
your
has_manyassociations. - have_one tests your
has_oneassociations. - have_and_belong_to_many
tests your
has_and_belongs_to_manyassociations. - have_db_column tests that the table that backs your model has a specific column.
- have_db_index tests that the table that backs your model has an index on a specific column.
- have_readonly_attribute
tests usage of the
attr_readonlymacro. - serialize tests usage of the
serializemacro.
ActionController Matchers
- filter_param tests parameter filtering configuration.
- redirect_to tests that an action redirects to a certain location.
- render_template tests that an action renders a template.
- render_with_layout tests that an action is rendered with a certain layout.
- rescue_from tests usage
of the
rescue_frommacro. - respond_with tests that an action responds with a certain status code.
- route tests your routes.
- set_session makes
assertions on the
sessionhash. - set_the_flash makes
assertions on the
flashhash.
Independent Matchers
- delegate_method tests that an object forwards messages to other, internal objects by way of delegation.
Installation
RSpec
Include the gem in your Gemfile:
group :test do
gem 'shoulda-matchers', require: false
end
Then require the gem following rspec-rails in your rails_helper (or spec_helper if you're using RSpec 2.x):
require 'rspec/rails'
require 'shoulda/matchers'
Test::Unit
shoulda-matchers was originally a component of Shoulda, a meta-gem
that also provides should and context syntax via
shoulda-context. For this reason you'll want to include this
gem in your Gemfile instead:
group :test do
gem 'shoulda'
end
Non-Rails apps
Once it is loaded, shoulda-matchers automatically includes itself into your test framework. It will mix in the appropriate matchers for ActiveRecord, ActiveModel, and ActionController depending on the modules that are available at runtime. For instance, in order to use the ActiveRecord matchers, ActiveRecord must be present beforehand.
If your application is written against Rails, everything should "just work", as shoulda-matchers will most likely be declared after Rails in your Gemfile. If your application is written against another framework such as Sinatra or Padrino, you may have a different setup, so you will want to ensure that you are requiring shoulda-matchers after the components of Rails you are using. For instance, if you wanted to use and test against ActiveModel, you'd say:
gem 'activemodel'
gem 'shoulda-matchers'
and not:
gem 'shoulda-matchers'
gem 'activemodel'
