ruby-on-rails-3 - 具有rspec2 beta 5和rails3 beta2的Shoulda宏

Question

我已经按照以下步骤设置了Rspec2 beta5和Shoulda，以便在rspec模型测试中使用Shoulda宏。
=================

现在我们可以开箱即用使用shoda-matchers。
只需在您的Gemfile中添加gem shoulda-matchers即可，而在spec_helper或其他黑客中则一无所有。它只是运行。
=================
gem 文件

group :test do
  gem "rspec", ">= 2.0.0.beta.4"
  gem "rspec-rails", ">= 2.0.0.beta.4"
  gem 'shoulda',          :git => 'git://github.com/bmaddy/
shoulda.git'
  gem "faker"
  gem "machinist"
  gem "pickle",           :git => 'git://github.com/codegram/
pickle.git'
  gem 'capybara',         :git => 'git://github.com/jnicklas/
capybara.git'
  gem 'database_cleaner', :git => 'git://github.com/bmabey/
database_cleaner.git'
  gem 'cucumber-rails',   :git => 'git://github.com/aslakhellesoy/
cucumber-rails.git'
end

spec_helper.rb

Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each {|f| require f}

require 'shoulda'

Rspec.configure do |config|

规范/型号/导出_spec.rb

require 'spec_helper'

describe Outlet do
  it { should validate_presence_of(:name) }
end

当我运行规范时，出现以下错误。

为什么是“未定义的方法”？肩部是否已被加载？

Answer 1

使用RSpec 2.0.0.beta.19

# Gemfile
group :test do
  gem "rspec", ">= 2.0.0.beta.19"
  gem "rspec-rails", ">= 2.0.0.beta.17"
  gem "shoulda"
end

# spec/spec_helper.rb
require 'rspec/rails'
require 'shoulda/integrations/rspec2' # Add this line

# In your specs....
it { should validate_presence_of(:name) }

现在，运行 rake spec应该加载并运行包括RSpec 2匹配器在内的规范。
