Question

您好，我有一个Rspec测试即可为用户控制器索引操作做。对于用户身份验证，我自己编码，而不是使用任何宝石。

在修改运行测试时出现此错误。我查找了所有解决方案，没有任何效果。

  2) UsersController GET #index redirects visitor
     Failure/Error: user_logged_in
     ActionView::Template::Error:
       undefined method `children' for nil:NilClass

这是测试。

require "rails_helper"

RSpec.describe UsersController, type: :controller do
  let!(:user) { create(:user) }

  let!(:users) do
    users = []
    3.times { users << create(:user) }
    users
  end

  describe "GET #index" do
    before  do
      user_logged_in
      create(users)
    end

    it "user renders template and shows users" do
      get :index
      expect(response).to render_template(:index)
      expect(response).to have_http_status(:success)
      expect(assigns(:users)).to eq(users)
    end

    it "redirects visitor" do
      get :index
      it { expect(response).to redirect_to(root_path) }
    end
  end
end

这是rails_helper

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)

abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'spec_helper'
require 'rspec/rails'
require "shoulda/matchers"

ActiveRecord::Migration.maintain_test_schema!

RSpec.configure do |config|
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.include FactoryGirl::Syntax::Methods
  config.use_transactional_fixtures = true
  config.infer_spec_type_from_file_location!
  config.include Capybara::DSL
end

def admin_logged_in
  visit login_path
  fill_in 'Email', with: admin.email
  fill_in 'Password', with: admin.password
  click_button 'Log In'
end

 def user_logged_in
  visit login_path
  fill_in 'Email', with: user.email
  fill_in 'Password', with: user.password
  click_button 'Log In'
end

没有看到完整的代码，很难判断。我想到的一件事是，我认为你滥用it {}语法。为什么不把它重写为

it "redirects visitor" do
  get :index
  expect(response).to redirect_to(root_path)
end

ActionView :: Template :: Error：未定义的方法`children'代表nil：NilClas
