自定义设计会话控制器的rspec测试失败,AbstractController::ActionNotFound

devise rspec controller ruby-on-rails

kaihowl · 技术社区 · 15 年前

我目前正在尝试用rspec测试一个定制的device会话控制器。我的控制器如下:

class SessionsController < Devise::SessionsController

  def create 
    #valid email?
    if !(params[:email] =~ /^[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,}$/)
      set_flash_message :notice, "Please enter a valid e-mail address!"
    end

    super
  end
end

我的RSPEC控制器测试是:

require 'spec_helper'
require 'devise/test_helpers'

describe SessionsController do  

  it "should put a warning on invalid mail address login attempt" do
    post :create, :user => {:email => 'invalidEmailAddress'}
    response.should contain "Please enter a valid e-mail address!"
  end

  it "should put no warning on valid mail address login attempt" do
    pending
  end
end

如果我执行rspec测试,它将失败,并出现以下行:

Failure/Error: post :new, :user => {:email => 'invalidEmailAddress'}
     AbstractController::ActionNotFound
     # ./spec/controllers/sessions_controller_spec.rb:7

平台上的提示设计wiki以及 this post 没有解决这个问题。谢谢你的帮助。

添加

我进一步调查。我实际上能够通过添加到控制器规范中的以下内容来“消除”错误:

before(:each) do
  request.env['devise.mapping'] = Devise.mappings[:user]
end

但现在出现了一个新错误:

Failure/Error: post :create  #currently fails with multiple render warning
Render and/or redirect were called multiple times in this action. Please note that you may only call render OR redirect, and at most once per action. Also note that neither redirect nor render terminate execution of the action, so if you want to exit an action after redirecting, you need to do something like "redirect_to(...) and return".

即使在继承控制器中遗漏了create方法,也会出现错误。例如,get:new上不会出现错误。似乎是post:只创建。我没主意了?有什么帮助吗? 谢谢!

我最终解决了我的问题,包括设计测试帮助器,在我的测试中调用方法设置\控制器\并执行请求。env[“device.mapping”]=device.mappings[:user]。就像这样:

require 'test_helper'

class SessionsControllerTest < ActionController::TestCase
    include Devise::TestHelpers

    test "should reject invalid captcha" do
       setup_controller_for_warden
       request.env["devise.mapping"] = Devise.mappings[:user]

       get :new

       assert_response :success
   end
end

但是,不确定您的双渲染问题,您确定应该调用post:create-then-render吗?我不知道RSPEC应该如何工作。
