黄瓜路由问题中的RSpec :: Expectations :: ExpectationNotMetError

我开始通过黄瓜研究BDD。 (使用Rails-3,gem'cucumber-rails')
我想在成功登录后重定向到用户个人资料页面(/ users / id) 我在控制器中定义为(redirect_to user_path(@user))和我在黄瓜中定义的相同的东西(page.current_path.should == user_path(@user))

在我的step_definition

Given /^a user visits the signin page$/ do
  visit signin_path
end

When /^he log in as "(.*)\/(.*)"$/ do |email, password|
  @email = email
  fill_in "email", with: email
  fill_in "password", with: password
  click_button "Login"
end

Then /^he should see a signin link$/ do
  page.should have_link('Sign in', href: signin_path)
end

Then /^he should see his profile page$/ do
  @user = User.where("email = ?", @email)
  page.current_path.should == user_path(@user)
end

在我的控制器中

class SessionsController < ApplicationController

 def create
  @user = User.find_by_email(params[:session][:email].downcase)
  if @user && @user.authenticate(params[:session][:password])
   sign_in @user      
   redirect_to user_path(@user)               
  else
   flash.now[:error] = 'Invalid email/password combination'
   render 'new'
  end
 end
end

现在运行黄瓜时,我收到了这个错误:

expected: "/users/%23%3CActiveRecord::Relation:0x000000062fbec0%3E"
       got: "/users/4" (using ==) (RSpec::Expectations::ExpectationNotMetError)

在我的features / support / env.rb中:

require File.expand_path(File.dirname(__FILE__) + '/../../config/environment')
require 'cucumber/rails'
require 'rspec/expectations'

请回答我做错的地方。

答案 0 :(得分:0)

步骤定义中的此代码是问题:

Then /^he should see his profile page$/ do
  @user = User.where("email = ?", @email)
  page.current_path.should == user_path(@user)
end

User.where将始终返回关系,即使结果只是一条用户记录,因此错误消息的ActiveRecord::Relation部分也是如此。

如果您确定只返回一个用户,则可以将其换成User.find_by_email(@email)User.where(:email => @email).first,以获取单个用户实例。
