ruby-on-rails-3 – 如何在rails 3中没有观察者运行rspec？

与Rails 3.1一起使用时,no_peeping_toms将输出废弃警告.它目前有 7 pull requests打开以删除这些弃用警告,但是 gem is not necessary with Rails 3.1+.Rails 3.1添加到ActiveModel(因此ActiveRecord)启用和 disable观察者的能力.

您可以将以下行放在spec_helper中以关闭所有ActiveRecord-descendant模型上的所有观察者：

# spec/spec_helper.rb
...
RSpec.configure do |config|
  ...
  config.before do
    ...
    ActiveRecord::Base.observers.disable :all # <-- Turn 'em all off!
  end
end

您可以通过使用enable方法在您的规格中包含操作来有选择地重新启动它们来测试其行为.

# spec/models/foo_observer_spec.rb
describe FooObserver do
  subject { FooObserver.instance }

  it 'notices when new Foos are created' do
    subject.should_receive(:after_create)

    Foo.observers.enable :foo_observer do # <- Turn FooObserver on
      Foo.create('my new foo')
    end                                   # <- ... and then back off
  end
end
