我用
this book研究了RoR(Ruby-2.1,Rails 4.x)的api教程.
这是一本很好的书,但我在第5章的rspec测试中得到了这个问题.(请参阅该章的清单5.9.)
Failure/Error: authentication.stub<:request>.and_return<request> #<Authentication:0x000000075fe220> does not implement: request
源代码：
class Authentication
include Authenticable
end
describe Authenticable do
let(:authentication) { Authentication.new }
describe "#current_user" do
before do
@customer = FactoryGirl.create :customer
request.headers["Authorization"] = @customer.auth_token
authentication.stub(:request).and_return(request)
end
it "returns the user from the authorization header" do
expect(authentication.current_user.auth_token).to eql @customer.auth_token
end
end
end
怎么解决这个问题？
解决方法
如果您想使用rspec 3,也许您可以用以下代码替换代码：
规格/控制器/关切/ authenticable_spec.rb
require 'rails_helper'
class Authentication
include Authenticable
end
describe Authenticable,:type => :controller do
let(:authentication) { Authentication.new }
describe "#current_user" do
before do
@user = FactoryGirl.create :user
request.headers["Authorization"] = @user.auth_token
allow(authentication).to receive(:request).and_return(request)
end
it "returns the user from the authorization header" do
expect(authentication.current_user.auth_token).to eql @user.auth_token
end
end
end
应用程序/控制器/关切/ authenticable.rb
module Authenticable
# Devise methods overwrites
def current_user
@current_user ||= User.find_by(auth_token: request.headers['Authorization'])
end
def request
request
end
end
