# shoulda-matchers [![Build Status](https://secure.travis-ci.org/thoughtbot/shoulda-matchers.png?branch=master)](http://travis-ci.org/thoughtbot/shoulda-matchers)
|
||
|
|
||
|
[Official Documentation](http://rubydoc.info/github/thoughtbot/shoulda-matchers/master/frames)
|
||
|
|
||
|
Test::Unit- and RSpec-compatible one-liners that test common Rails functionality.
|
||
|
These tests would otherwise be much longer, more complex, and error-prone.
|
||
|
|
||
|
Refer to the [shoulda](https://github.com/thoughtbot/shoulda) gem if you want to know more
|
||
|
about using shoulda with Test::Unit.
|
||
|
|
||
|
Please report bugs on the [shoulda issue tracker](https://github.com/thoughtbot/shoulda/issues).
|
||
|
|
||
|
## ActiveRecord Matchers
|
||
|
|
||
|
Matchers to test associations:
|
||
|
|
||
|
describe Post do
|
||
|
it { should belong_to(:user) }
|
||
|
it { should have_many(:tags).through(:taggings) }
|
||
|
end
|
||
|
|
||
|
describe User do
|
||
|
it { should have_many(:posts) }
|
||
|
end
|
||
|
|
||
|
## ActiveModel Matchers
|
||
|
|
||
|
Matchers to test validations and mass assignments:
|
||
|
|
||
|
describe Post do
|
||
|
it { should validate_uniqueness_of(:title) }
|
||
|
it { should validate_presence_of(:body).with_message(/wtf/) }
|
||
|
it { should validate_presence_of(:title) }
|
||
|
it { should validate_numericality_of(:user_id) }
|
||
|
end
|
||
|
|
||
|
describe User do
|
||
|
it { should_not allow_value("blah").for(:email) }
|
||
|
it { should allow_value("a@b.com").for(:email) }
|
||
|
it { should ensure_inclusion_of(:age).in_range(1..100) }
|
||
|
it { should_not allow_mass_assignment_of(:password) }
|
||
|
end
|
||
|
|
||
|
## ActionController Matchers
|
||
|
|
||
|
Matchers to test common patterns:
|
||
|
|
||
|
describe PostsController, "#show" do
|
||
|
context "for a fictional user" do
|
||
|
before do
|
||
|
get :show, :id => 1
|
||
|
end
|
||
|
|
||
|
it { should assign_to(:user) }
|
||
|
it { should respond_with(:success) }
|
||
|
it { should render_template(:show) }
|
||
|
it { should_not set_the_flash }
|
||
|
end
|
||
|
end
|
||
|
|
||
|
## Installation
|
||
|
|
||
|
In Rails 3 and Bundler, add the following to your Gemfile:
|
||
|
|
||
|
group :test do
|
||
|
gem "rspec-rails"
|
||
|
gem "shoulda-matchers"
|
||
|
end
|
||
|
|
||
|
Shoulda will automatically include matchers into the appropriate example groups.
|
