使用Devise在Rails中进行功能测试

gem 'devise'

rails generate devise:install
rails generate devise User

class User < ApplicationRecord
  # Devise modules
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable

  # Custom fields and validations
  validates :username, presence: true, uniqueness: true
end

rails db:migrate

config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }

require 'test_helper'

class UsersControllerTest < ActionDispatch::IntegrationTest
  include Devise::Test::IntegrationHelpers

  setup do
    @user = users(:one)
    sign_in @user
  end

  test "should get index" do
    get users_url
    assert_response :success
  end

  test "should create user" do
    assert_difference('User.count') do
      post users_url, params: { user: { username: 'newuser', password: 'password' } }
    end

    assert_redirected_to user_url(User.last)
  end

  # 其他功能测试...
end
