您好我需要写大约50个rspec测试。没有用于用户模型的gem。它是从头开始创建的。如何为rspec创建登录助手？
请记住这是针对Rspec而不是水豚
谢谢。
这是会话控制器
class SessionsController＆lt; ApplicationController中
zip "/Applications/Sublime Text.app/Contents/MacOS/Packages/Default.sublime-package" new_templates.py这是会议助手
def new
end
def create
user = User.find_by(email: params[:sessions][:email].downcase)
if user && user.authenticate(params[:sessions][:password])
if user.activated?
log_in user
params[:sessions][:remember_me] == '1' ? remember(user) : forget(user)
redirect_back_or user
else
message = "Account not activated. "
message += "Check your email for the activation link."
flash[:warning] = message
redirect_to root_url
end
else
flash.now[:danger] = 'Invalid email/password combination'
render 'new'
end
end
def destroy
log_out if logged_in?
redirect_to root_url
end
end
这是我拥有的用户控制器规范。问题是我没有登录（用户）帮助方法。有谁知道如何写一个？我查了一下，找不到有关它的更多信息。
需要“rails_helper” 需要“test_helper”
module SessionsHelper
# Logs in the given user.
def log_in(user)
session[:user_id] = user.id
end
# Returns the user corresponding to the remember token cookie.
def current_user
if (user_id = session[:user_id])
@current_user ||= User.find_by(id: user_id)
elsif (user_id = cookies.signed[:user_id])
user = User.find_by(id: user_id)
if user && user.authenticated?(:remember, cookies[:remember_token])
log_in user
@current_user = user
end
end
end
# Returns true if the user is logged in, false otherwise.
def logged_in?
!current_user.nil?
end
# Logs out the current user.
def log_out
session.delete(:user_id)
@current_user = nil
end
# Remembers a user in a persistent session.
def remember(user)
user.remember
cookies.permanent.signed[:user_id] = user.id
cookies.permanent[:remember_token] = user.remember_token
end
# Returns true if the given user is the current user.
def current_user?(user)
user == current_user
end
# Forgets a persistent session.
def forget(user)
user.forget
cookies.delete(:user_id)
cookies.delete(:remember_token)
end
# Logs out the current user.
def log_out
forget(current_user)
session.delete(:user_id)
@current_user = nil
end
# Redirects to stored location (or to the default).
def redirect_back_or(default)
redirect_to(session[:forwarding_url] || default)
session.delete(:forwarding_url)
end
# Stores the URL trying to be accessed.
def store_location
session[:forwarding_url] = request.url if request.get?
end
end
当我运行上述测试时，我收到此错误
RSpec.describe UsersController, type: :controller do
let!(:admin) { create(:user, password: "Password123", admin: true) }
let!(:user) { create(:user, password: "Password456", admin: false) }
let!(:update_params) do
{ id: user.id, user_id: user.id, user: user }
end
let!(:users) do
[admin, user] + 3.times.map { create(:user) }
end
let!(:user_params) { user_params = { username: "username#{rand(1000)}",
email: "user#{rand(1000)}@factory.com",
password: "Password123",
password_confirmation: "Password123",

expect(assigns(:users).map(&:id)).to eq users.map(&:id)
end

expect(response).to redirect_to(root_path)
end

expect(response).to have_http_status(:success)
end
end

end
end

end
end

expect(assigns(:user)).to eq(user)
end
end
# describe "DELETE #destroy" do

# end
end
这是因为我的用户没有登录。拥有一个登录帮助程序方法会很棒，它会在之前登录用户。
答案 0 :(得分：1)
我已在我的test_helper.rb中为我的测试实现了一些与用户登录相关的方法，它看起来像这样：
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'
class ActiveSupport::TestCase
# Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
fixtures :all
# Returns true if a test user is logged in.
def is_logged_in?
!session[:user_id].nil?
end
# Logs in a test user.
def log_in_as(user, options = {})
password = options[:password] || 'password'
remember_me = options[:remember_me] || '1'
if integration_test?
post login_path, session: { email: user.email,
password: password,
remember_me: remember_me }
else
session[:user_id] = user.id
end
end
private
# Returns true inside an integration test.
def integration_test?
defined?(post_via_redirect)
end
end
它有log_in_as方法，可以吸引用户，您可以在测试中使用它。 e.g：
describe "POST #update" do
it "user updated" do
log_in_as user # now you have log_in_as method implemented
patch :update, update_params
expect(response).to redirect_to(assigns(:user))
expect(assigns(:user)).to eq(user)
end
end
您可能需要对上述代码进行一些修改才能使其在您的应用程序中运行，但它应该让您清楚地了解如何执行此操作。我希望这会有所帮助。
