编辑 请阅读我对这个问题的评论
我很新手rails，请多多包涵。 我一直在尝试使用factory girl和rspec配置Devise的测试。这花了我最好的2个小时，搜索了一半的互联网也没有结果。尽管有很多关于我的问题的线程，但我就是想不出来。
这是我的/spec文件的样子。
GET Home Gives the correct status code
Failure/Error: sign_in user
NoMethodError:
undefined method `sign_in' for #<RSpec::Core::ExampleGroup::Nested_2:0x00000106f32558>
# ./spec/models/user_spec.rb:6:in `block (2 levels) in <top (required)>
这是我在尝试进行以下测试时收到的错误信息：
user_spec.rb：
require 'spec_helper'
describe "GET Home" do
before do
##I have tried all sorts of things here. I have also tried to define a module in devise.rb (see note below*), and then call that module here instead of the 2 lines below. But I get the same error, no local variable or undefined method for ...
user = FactoryGirl.create(:user)
sign_in user
end
describe "GET /Home"
it "Gives the correct status code" do
get root_path
response.status.should be(200)
end
end
在spec/factories/users.rb文件中：
FactoryGirl.define do
factory :user do
name "Christoffer"
email "test@test2.com"
password "testtest"
password_confirmation "testtest"
end
end
以下内容包含在
spec_helpers.rb文件中。config.include FactoryGirl::Syntax::Methods
config.include Devise::TestHelpers, :type => :controller
现在，通过这样做，我得到了上面的错误。有人能解释一下我做错了什么吗？可能是很明显的问题，因为我对Rails的方式并不是很熟悉。
*注意（我试图在devise.rb中定义并插入before do模块）：
module ValidUserRequestHelper
# Define a method which signs in as a valid user.
def sign_in_as_a_valid_user_nommels
# ASk factory girl to generate a valid user for us.
@user ||= FactoryGirl.create :user
# We action the login request using the parameters before we begin.
# The login requests will match these to the user we just created in the factory, and authenticate us.
post_via_redirect user_session_path, 'user[email]' => @user.email, 'user[password]' => @user.password
end
end
