使用raise_error进行RSpec授权测试不起作用

Question

我正在尝试测试未登录用户的行为如何

  describe "not logged in user" do
   user_no_rights

    it "can't access action index" do
      expect(get :index).to raise_error(CanCan::AccessDenied)
    end
  end

我运行rspec时的输出

  Failure/Error: expect(get :index).to raise_error("CanCan::AccessDenied:You are not authorized to access this page.")
     CanCan::AccessDenied:
       You are not authorized to access this page.

所以它看起来像是正确的execption,但为什么规范不通过？

Answer 1

我把规格改为:

 describe "not logged in user" do
   user_no_rights

    it "can't access action index" do
      expect{get :index}.to raise_error(CanCan::AccessDenied)
    end
 end

它的工作原理.感谢托马斯!:-)
