javascript - Rspec 和 javascript

Question

在我的 ruby​​ 应用程序中，我有一个带有一些 javascript 函数的页面，负责填写表单字段。问题是，当我尝试使用 rspec 对此页面进行测试时，javascript 似乎没有运行，导致表单上出现错误。

有什么办法可以解决这个问题吗？

编辑(使用 Fred 建议)

我的spec_helper.rb 文件如下所示:

require 'capybara/rspec'
require 'factory_girl_rails'
require 'capybara/poltergeist'

require 'support/mailer_macros'
require 'support/test_helper'

Capybara.javascript_driver = :poltergeist

RSpec.configure do |config|
  config.expect_with :rspec do |expectations|
    expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end

  config.include FactoryGirl::Syntax::Methods

  config.include Capybara::DSL

  config.include(MailerMacros)
  config.include(TestHelper)
  config.before(:each) { reset_email }

  config.expect_with :rspec do |c|
    c.syntax = [:should, :expect]
  end

end

我的测试如下所示:

require 'rails_helper'

RSpec.describe "Courses", type: :request do
  let(:user) { FactoryGirl.create(:user) }

  it "should create, show, edit and delete a course" do
    login user
    visit course_types_path("en")
    fill_in "course_type_name", :with => "driving"
    click_button "Add"
    visit courses_path("en")
    current_path.should eq(courses_path("en"))
    click_link "Create new course"
    current_path.should eq(new_course_path("en"))
    select "driving", from: "course_course_type_id"
    fill_in "course_name", :with => "course 1"
    fill_in "course_price", :with => "12"
    click_link "add_date_link"
    select "John Doe", from: "course_teacher_id"
    fill_in "course_max_students", :with => "1"
    fill_in "course_address", :with => "Rua Adriano Correia de Oliveira A, Laranjeiro, Portugal"
    click_button "Create new course"
    current_path.should eq(courses_path("en"))
    page.should have_content("New course created successfully")
    page.should have_content("course 1")
  end
end

什么时候改变它“应该创建、显示、编辑和删除类(class)”，js: true do

其他测试，在开始之前工作无法通过，并且当单击链接时页面似乎没有转到正确的位置(改为转到根目录)，并且此测试未通过给出: ActionController::RoutingError:没有路由匹配[GET]“/fonts/fontawesome-webfont.woff”

要实现您想要的目标，您需要 capybara , poltergeist和 phantomJS。安装时poltergeist会自动下载phantomJS。
