在水豚/rspec 规范期间不加载资产

Question

我正在使用 rspec、capybara 和 launchy 来测试我的 Web 应用程序。

这是我的规格：

require 'spec_helper'

describe "Routes" do
    describe "GET requests" do
        it "GET /root_path" do
            visit root_path
        page.should have_content("All of our statuses")
        click_link "Post a New Status"
        page.should have_content("New status")
        fill_in "status_name", with: "Jimmy balooney"
        fill_in "status_content", with: "Oh my god I am going insaaaaaaaaane!!!"
        click_button "Create Status"
        page.should have_content("Status was successfully created.")
        click_link "Statuses"
        page.should have_content("All of our statuses")
        page.should have_content("Jimmy balooney")
        page.should have_content("Oh my god I am going insaaaaaaaaane!!! ")
        save_and_open_page
        end
    end
end

我的.rspec

--color
--order default

和我的 spec_helper.rb:

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

# Checks for pending migrations before tests are run.
# If you are not using ActiveRecord, you can remove this line.
ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)

RSpec.configure do |config|
  # ## Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr
  config.before(:suite) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.start
    DatabaseCleaner.clean
  end

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

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # If true, the base class of anonymous controllers will be inferred
  # automatically. This will be the default behavior in future versions of
  # rspec-rails.
  config.infer_base_class_for_anonymous_controllers = false

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = "random"
end

如果你回顾我的规范，你会看到一个 rspec 规范，它使用水豚来浏览我的应用程序，并通过调用启动 gem 的 save_and_open_page 方法在浏览器中打开这个最终页面以供人类查看。然而，在最后一页，没有显示 javascript 或 css，只有纯 HTML。

有人知道为什么会这样吗？我想测试 javascript，如果所有资产都已加载，我会更喜欢它。

Answer 1

里面

config.before(:suite) do

添加：

%x[bundle exec rake assets:precompile]

预编译您的 Rails 资产，然后在您的

test.rb

环境文件中添加：

config.action_controller.asset_host = "file://#{::Rails.root}/public"
config.assets.prefix = 'assets_test'

指向预编译资产的位置。现在您可以在运行 Capybara 时使用资产。 注意： 确保您是否使用 git 忽略该新文件夹。

Answer 2

您可以添加到

test.rb

：

config.assets.compile = true

Answer 3

我用这个解决了

config/test.rb

  config.assets.css_compressor = nil
  config.assets.compile = true

spec/rails_helper.rb

RSpec.configure do |config|
    config.before :all do
        if !ENV["ASSET_PRECOMPILE_DONE"]
          prep_passed = system "rails test:prepare"
          ENV["ASSET_PRECOMPILE_DONE"] = "true"
          abort "\nYour assets didn't compile. Exiting WITHOUT running any tests. Review the output above to resolve any errors." if !prep_passed
        end
     end
end
