ruby-on-rails - 将 cucumber 翻译成 rspec

Question

如何在 rspec 中编写以下功能？

Feature: Signing in; In order to use the site as a user, I want to be able to sign in

  Scenario: Signing in via confirmation
    Given there are the following users:
      |email            |password|
      |user@example.com |password|
    And "user@example.com" opens the mail with subject
      "Confirmation instructions"
    And they click the first link in the email
    Then I should see "Your account was successfully confirmed"
    And I should see "Signed in as user@example.com"

Answer 1

这看起来像是 Rails 3 in Action 第一版中的功能，我目前正在将其重写到第二版中。第二版的特点是这样的:

feature 'Signing in' do
  before do
    Factory(:user, :email => "ticketee@example.com")
  end

  scenario 'Signing in via confirmation' do
    open_email "ticketee@example.com", :with_subject => /Confirmation/
    click_first_link_in_email
    page.should have_content("Your account was successfully confirmed")
    page.should have_content("Signed in as ticketee@example.com")
  end
end

这是使用 Capybara 的新功能语法，其所有意图和目的与 RSpec 的 context block 相同。通过使用 before，您可以设置一个可以在此功能中使用的用户。在该场景中，您使用 open_email 方法(由 email_spec gem 提供)打开电子邮件，并使用该 gem 提供的 click_first_link_in_email 方法来执行这两个步骤。

然后会将您带到一个页面，您应该能够在其中看到所需的两条消息。
