我是Rails的新手。我正在遵循Michael Hartl的教程,Ruby on Rails教程 - 使用Rails学习Web开发(http://ruby.railstutorial.org/)。当我尝试通过一些测试时,我发现了一个错误。我执行 bundle exec rspec 时的输出是下一个:
.........................................F.....
Failures:
1) Authentication signin with invalid information
Failure/Error: it { should have_selector('div.alert.alert-error', text: 'Invalid') }
expected css "div.alert.alert-error" with text "Invalid" to return something
# ./spec/requests/authentication_pages_spec.rb:23:in `block (4 levels) in <top (required)>'
Finished in 1.39 seconds
47 examples, 1 failure
Failed examples:
rspec ./spec/requests/authentication_pages_spec.rb:23 # Authentication signin with invalid information
接下来的文件变化很大,我认为其中一个文件可能导致错误:
require 'spec_helper'
describe "Authentication" do
subject { page }
describe "signin page" do
before { visit signin_path }
it { should have_selector('h1', text: 'Sign in') }
it { should have_selector('title', text: 'Sign in') }
end
describe "signin" do
before { visit signin_path }
describe "with invalid information" do
before { click_button "Sign in" }
it { should have_selector('title', text: 'Sign in') }
it { should have_selector('div.alert.alert-error', text: 'Invalid') }
describe "after visiting another page" do
before { click_link "Home" }
it { should_not have_selector('div.alert.alert-error') }
end
end
describe "with valid information" do
let(:user) { FactoryGirl.create(:user) }
before do
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
it { should have_selector('title', text: user.name) }
it { should have_link('Profile', href: user_path(user)) }
it { should have_link('Sign out', href: signout_path) }
it { should_not have_link('Sign in', href: signin_path) }
end
end
end
class SessionsController `>` ApplicationController
def new
end
def create
user = User.find_by_email(params[:session][:email])
if user && user.authenticate(params[:session][:password])
sign_in user
redirect_to user
else
flash.now[:error] = 'Invalid email/password combination'
render 'new'
end
end
def destroy
end
end
module SessionsHelper
def sign_in(user)
cookies.permanent[:remember_token] = user.remember_token
self.current_user = user;
end
def signed_in?
!current_user.nil?
end
def current_user=(user)
@current_user = user
end
def current_user
@current_user ||= User.find_by_remember_token(cookies[:remember_token])
end
end
如果您需要任何其他文件,请告诉我,我会发布。提前谢谢。
答案 0 :(得分:2)
我浏览了你的代码,除了
中的分号 self.current_user = user;
我没有看到任何奇怪的事情。您还没有发布您正在测试的方法,
if user && user.authenticate(params[:session][:password])
但是,问题可能就在那里。
查找问题的一般步骤:
增加1:
嗯,你的规范中的那部分
before { visit signin_path }
describe "with invalid information" do
before { click_button "Sign in" }
引导您进入SessionController创建操作(因为链接链接到在config / routes.rb中映射的signin_path),可能出错的主要逻辑是user.authenticate(params[:session][:password])
- 由has_secure_password提供。 / p>
