水豚上传图像问题

capybara rspec testing ruby ruby-on-rails

ruby_dev · 技术社区 · 8 年前

我需要用Capybara和Selenium测试文件上传页面。

我写了这个测试:

require 'rails_helper'

describe 'Images', type: :feature do
  before(:each) do
    @user = create(:user)
    visit '/users/sign_in'
    fill_in 'sing-in-email-input', with: @user.email
    fill_in 'sign-in-password-input', with: @user.password
    click_button 'btn-sign-in'
    visit '/categories'
    click_on 'btn-new-category'
    expect(current_path) == new_category_path
    fill_in 'category_name', with: 'Test'
    click_button 'btn-create category'
    visit '/categories'
    first('.fa', :visible => false).click
    expect(current_path) == category_path(id: Category.last.slug.to_s)
  end

  it 'should allow a registered user to create image and go to it page', js: true do
    click_on 'btn-upload-images'
    expect(current_path) == new_image_path(id: Category.last.slug.to_s)
    attach_file('image[image]',
                File.join(Rails.root, '/spec/fixtures/solnce-kosmos-merkuriy.jpg'), :visible => false)
    click_on('btn-upload-img')
  end
end

我无法继续编写此测试,并检查此图像是否已成功上载,因为在此行中:

单击('btn-upload-img')

我遇到了以下错误:

Failure/Error: raise ActionController::RoutingError, "No route matches [#{env['REQUEST_METHOD']}] #{env['PATH_INFO'].inspect}"

我已经检查过了我真的有这个文件

/规格/固定装置/solnce kosmos merkuriy。jpg公司

在正确的地方。

这是我的 /配置/初始化器/载波。rb型

if Rails.env.test? || Rails.env.cucumber?
  CarrierWave.configure do |config|
    config.storage = :file
    config.enable_processing = false
  end

  # make sure our uploader is auto-loaded
  ImageUploader

  # use different dirs when testing
  CarrierWave::Uploader::Base.descendants.each do |klass|
    next if klass.anonymous?
    klass.class_eval do
      def cache_dir
        "#{Rails.root}/spec/support/uploads/tmp"
      end

      def store_dir
        "#{Rails.root}/spec/support/uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
      end
    end
  end
end

我的 rails\u助手。rb型

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

    login_as(resource, scope: scope)
  end

  def sign_out(resource_or_scope)

我的 视图模板 对于此图像上载页面:

.row.main-new-image
  = form_for @image, url: create_image_path, html: {multipart: true, method: :post, remote: true } do |form|
    #new_image_error_explanation
    .field

        %span.btn.btn-new-image{id: 'new-image-button'}
          %p#p-new-image-button Choose image

    .field

    .actions
      .p.text-center
        = form.submit 'Upload', class: 'btn button-upload-img', id: 'btn-upload-img'

我所有其他的水豚和RSpec测试都很好。

请帮助我了解这个问题的原因,以及如何解决和预防。

如果能帮助解决这个问题,我可以提供更多信息。

更新1

在我读了托马斯·沃尔波尔的评论后,我决定更新我的代码并尝试其他一些功能。我包括新宝石

gem“database\u cleaner”

此外,我还添加了新代码以清除测试上载的代码。此处已更新 rails\u助手。rb型

require 'support/factory_bot'
require 'spec_helper'
require 'shoulda/matchers'
require 'capybara/rspec'
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'rspec/rails'

ActiveRecord::Migration.maintain_test_schema!
module DeviseRequestSpecHelpers

  include Warden::Test::Helpers

  def sign_in(resource_or_scope, resource = nil)
    resource ||= resource_or_scope
    scope = Devise::Mapping.find_scope!(resource_or_scope)
    login_as(resource, scope: scope)
  end

  def sign_out(resource_or_scope)
    scope = Devise::Mapping.find_scope!(resource_or_scope)
    logout(scope)
  end
end

RSpec.configure do |config|
  Capybara.javascript_driver = :selenium
  Capybara.ignore_hidden_elements = true
  Capybara.register_driver :selenium do |app|
    Capybara::Selenium::Driver.new(app, browser: :firefox)
  end

  config.include Capybara::DSL
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.before(:suite) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
  end
  
  config.around(:each) do |example|
    DatabaseCleaner.cleaning do
      example.run
    end
  end
  
  config.after(:all) do
    if Rails.env.test?
      FileUtils.rm_rf(Dir["#{Rails.root}/spec/support/uploads"])
    end
  end

end

Shoulda::Matchers.configure do |config|
  config.integrate do |with|
    with.test_framework :rspec

    with.library :rails
  end
end

这是我的最新测试

require 'rails_helper'

describe 'Images', type: :feature do
  before(:each) do
    @user = create(:user)
    visit '/users/sign_in'
    fill_in 'sing-in-email-input', with: @user.email
    fill_in 'sign-in-password-input', with: @user.password
    click_button 'btn-sign-in'
    visit '/categories'
    click_on 'btn-new-category'
    have_current_path(new_category_path)
    fill_in 'category_name', with: 'Test'
    click_button 'btn-create category'
    visit '/categories'
    first('.fa', :visible => false).click
    have_current_path(category_path(id: Category.last.slug.to_s))
  end

  #ISSUE WITH
  it 'should allow a registered user to create image and go to it page', :driver => :selenium do
    click_on 'btn-upload-images'
    have_current_path(new_image_path(id: Category.last.slug.to_s))
    attach_file('image[image]',
                File.join(Rails.root, '/spec/fixtures/solnce-kosmos-merkuriy.jpg'), :visible => false)
    click_on('btn-upload-img')
  end
end

正如托马斯·沃尔波尔(ThomasWalpole)告诉我的,我检查了测试日志,然后看到了下一个(关于当前测试):

据我所知,图像已成功上传。但我还是有这个错误

Failure/Error: raise ActionController::RoutingError, "No route matches [#{env['REQUEST_METHOD']}] #{env['PATH_INFO'].inspect}"
     
     ActionController::RoutingError:
       No route matches [GET] "/home/Anton-S/RubymineProjects/rails_projects/gallery/spec/support/uploads/image/image/12/solnce-kosmos-merkuriy.jpg"

更新2

不幸的是,我找到的唯一解决办法就是 /配置/环境/测试。rb型

config.action_dispatch.show_exceptions = true

但我仍然认为有更好的解决办法。

Thomas Walpole 8 年前

因此,从日志中,我们可以看到文件正在成功上载。

问题是,当显示页面呈现时,图像被添加到HTML中,URL为“/主页/Anton-S/RubyMineProject/rails\u项目/库/规范/支持/上传/图像/图像/12/solnce kosmos merkuriy”。“jpg”不会起作用,因为rails应用程序不会响应来自外部的随机文件 public 应用程序根目录中的目录。这样做将是一个巨大的安全问题。最简单的解决方案是将图像存储到 平民的 目录,以便rails应用程序将其作为静态资产使用。类似于

  def cache_dir
    "public/test/uploads/tmp"
  end

  def store_dir
    "public/test/uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

注意:我还对您使用 have_current_path 匹配器。
