ruby-on-rails - rails : How to test state_machine?

Question

请帮我。我很困惑。我知道如何编写模型的状态驱动行为，但我不知道我应该在规范中写什么......

我的model.rb文件看看

class Ratification < ActiveRecord::Base
  belongs_to :user

  attr_protected :status_events

  state_machine :status, :initial => :boss do
    state :boss
    state :owner
    state :declarant
    state :done

    event :approve do
      transition :boss => :owner, :owner => :done
    end

    event :divert do
      transition [:boss, :owner] => :declarant
    end

    event :repeat do
      transition :declarant => :boss
    end

  end
end

我用 state_machine gem 。

请告诉我类(class)。

Answer 1

state_machine_rspec gem 包含许多用于编写简洁规范的辅助方法。

 describe Ratification do
   it { should have_states :boss, :declarant, :done, :owner }
   it { should handle_events :approve, when: :boss }
   it { should handle_events :approve, when: :owner }
   it { should handle_events :divert, when: :boss }
   it { should handle_events :divert, when: :owner }
   it { should handle_events :repeat, when: :declarant }
   it { should reject_events :approve, :divert, :repeat, when: :done }
   it { should reject_events :approve, :divert, :repeat, when: :done }
 end

这些 RSpec 匹配器将协助 state_machine来自高级别的规范。从这里开始，需要为 can_approve? 的业务案例编写规范。 , can_divert? , 和 can_repeat? .
