ruby-on-rails - 设计/ cucumber - 添加确认用户存在的步骤

Question

我是 cucumber 的新手，我发现以下片段来测试设计登录功能。然而，似乎又少了一步，我没有找到任何解决方案:

Given /^that a confirmed user exists$/ do
  pending # express the regexp above with the code you wish you had
end

这里的代码如下:

功能/身份验证/session.feature

Feature: Session handling
  In order to use the site
  As a registered user
  I need to be able to login and logout

Background: 
  Given that a confirmed user exists

Scenario Outline: Logging in
  Given I am on the login page
  When I fill in "user_email" with "<email>"
  And I fill in "user_password" with "<password>"
  And I press "Sign in"
  Then I should <action>
  Examples:
    |         email       |  password   |              action             |
    | minimal@example.com |  test1234   | see "Signed in successfully"    |
    | bad@example.com     |  password   | see "Invalid email or password" |

Scenario: Logging out
  Given I am logged in
  When I go to the sign out link
  Then I should see "Signed out successfully"

功能/step_definitions/authentication_steps.rb

# Session
Given /^I am logged in$/ do
  visit path_to('the login page')
  fill_in('user_email', :with => @user.email)
  fill_in('user_password', :with => @user.password)
  click_button('Sign in')
  if defined?(Spec::Rails::Matchers)
    page.should have_content('Signed in successfully')
  else
    assert page.has_content?('Signed in successfully')
  end
end

规范/工厂/user.rb

Factory.define :minimal_user, :class => User do |u|
  u.username 'minimal'
  u.email 'minimal@example.com'
  u.password 'test1234'
  u.password_confirmation 'test1234'
end

非常感谢您的帮助!!

您的标题说“验证用户是否存在”，但这可能不是您需要在那里执行的操作 - 您的 Given步骤不需要断言某些事情有效，它们调用代码来为您的场景创建应用程序状态。当然，它们仍然是测试，因为它们仍然可能失败。

我想你正在寻找这样的东西:

Given /^that a confirmed user exists$/ do
  Factory.create(:minimal_user)
end

这将从您的工厂定义中创建并保存一个新的确认用户，以便场景的其余部分可以继续。
