ruby-on-rails-3 - ActiveRecord::RecordNotFound:找不到 id= 的用户

Question

我正在使用 rspec 测试我的应用程序，我读到我必须在测试环境中创建一个用户，但不知道如何......这是代码:

require 'spec_helper'

    describe CarsController do
    describe "GET 'new'" do
            it "should be successful" do
            visit new_user_car_path(:user_id=>"28")#also try (current_user) but nothing
            response.should be_success
            end
        end
    end

当我运行它时，我收到了这条消息

Failure/Error: visit new_user_car_path(:user_id=>"28")
 ActiveRecord::RecordNotFound:
   Couldn't find User with id=28
 # ./app/controllers/cars_controller.rb:3:in `new'
 # ./spec/controllers/tanking_logs_controller_spec.rb:6:in `block (3 levels) in <top (required)>'

如果您需要更多代码，请告诉我

编辑。这个我试过了

require 'spec_helper'

describe CarsController do
describe "GET 'new'" do
    it "should be successful" do
        #user = User.create(...)
        @user = {:email => "user@example.com", :password => "foobar", :password_confirmation => "foobar" }
        visit new_user_car_path(@user) 
        response.should be_success
    end
end
end

现在我得到了这个错误:

 No route matches {:action=>"new", :controller=>"cars", :email=>"user@example.com", :password=>"foobar", :password_confirmation=>"foobar"}

您的测试数据库中没有 ID 为 28 的用户。您需要为您的测试数据库设定种子并使用您已知存在的用户 ID。

或者，按需创建新用户:

describe "GET 'new'" do
  it "should be successful" do
    user = User.create(...)
    visit new_user_car_path(user)#also try (current_user) but nothing
    response.should be_success
  end
end
