设置authenticity_token时RSpec + Poltergeist失败

标签： ruby-on-rails rspec capybara poltergeist

我正在尝试使用RSpec + Polgergeist测试我的Rails应用中的功能。

我的功能规格现在非常基础：

RSpec.feature 'Listing owners can create new listings' do
  let(:owner) { create(:user, :owner) }

  before do
    login_as owner
    # I've also tried this with as recommended by Devise when using Capybara-Webkit:
    # login_as(user, scope: :user, run_callbacks: false)
    visit new_listing_path
  end

  scenario 'successfully', js: true do
    fill_in 'Field 1', with: 'Example'
    click_link 'Create'

    # expectations here...
  end
end

我的 rails_helper.rb

中有以下内容 
require 'capybara/poltergeist'

RSpec.configure do |config|
  # ...
  config.include Warden::Test::Helpers, type: :feature
  config.after(type: :feature) { Warden.test_reset! }
  # ...
end

并在 support / poltergeist.rb 文件中

RSpec.configure do |config|
  Capybara.javascript_driver = :poltergeist

  # Increase timeout in case asset compilation
  # takes longer than anticipated.
  Capybara.register_driver :poltergeist do |app|
    Capybara::Poltergeist::Driver.new(app, {timeout: 60})
  end
end

失败的确切位置是这样的，我使用Vue.js设置CSRF令牌：

import Vue from 'vue/dist/vue.esm'
import VueResource from 'vue-resource'

Vue.use(VueResource)

document.addEventListener('DOMContentLoaded', () => {

  if(document.getElementById('listing-multistep') !== null) {
    Vue.http.headers.common['X-CSRF-Token'] = document.querySelector('input[name="authenticity_token"]').getAttribute('value');
    var listingForm = document.getElementById('listing_form');
    var listing = JSON.parse(listingForm.dataset.listing);

    // do magic....
  }
});

真实性令牌是从Rails表单部分 _form.html.erb 设置的：

<%= form_for(
  listing,
  html: { multipart: true, id: 'listing_form',
    data: {
      listing: listing.to_json(except: [:user_id, :created_at, :updated_at])
    }
  }) do |f| %>

  <fieldset class="listing-step" v-show="activeStep === 0">
    <%= render 'listings/form/basics', f: f, listing: listing %>
  </fieldset>

  <fieldset class="listing-step" v-show="activeStep === 1">
    <%= render 'listings/form/location', f: f, listing: listing %>
  </fieldset>

  <fieldset class="listing-step" v-show="activeStep === 2">
    <%= render 'listings/form/amenities', f: f, listing: listing %>
  </fieldset>

  <fieldset class="listing-step" v-show="activeStep === 3">
    <%= render 'listings/form/description', f: f, listing: listing %>
  </fieldset>
<% end %>

以这种方式设置CSRF令牌似乎在开发中工作，但是当我运行规范时，我看到以下错误：

Failure/Error: visit new_listing_path

     Capybara::Poltergeist::JavascriptError:
       One or more errors were raised in the Javascript code on the page. If you don't care about these errors, you can ignore them by setting js_errors: false in your Poltergeist configuration (see documentation for details).

       TypeError: null is not an object (evaluating 'document.querySelector('input[name="authenticity_token"]').getAttribute')
       TypeError: null is not an object (evaluating 'document.querySelector('input[name="authenticity_token"]').getAttribute')
           at http://127.0.0.1:54450/packs-test/dashboard-ca7eeed2cc4b22399ade.js:13086

所有我能想到的是，恶作剧者并没有等待DOM完全加载，但这很奇怪，因为我在document.addEventListener('DOMContentLoaded', () => {

中明确写了vue代码

另外，我还有一个 support / database_cleaner.rb 文件，其中包含以下内容：

RSpec.configure do |conf|
  conf.before(:suite) do
    DatabaseCleaner.clean_with :truncation
  end

  conf.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end

  conf.before(:each, js: true) do
    DatabaseCleaner.strategy = :truncation
  end

  conf.before(:each) do
    DatabaseCleaner.start
  end

  conf.after(:each) do
    DatabaseCleaner.clean
  end
end

知道可能导致上述错误的原因吗？任何帮助深表感谢！ 提前致谢
