为什么我的Rails Test :: Unit测试中我的fixture对象不可用？

Question

根据此Rails指南,如果您创建一个fixture,它将在您的测试类中可用.

我有这个夹具users.yml:

<%
  stan = User.new
  stan.username = 'stan'
  stan.set_hashed_password('mysterio')
  stan.email = 'stan@abc.com'
%>

stan:
  username: <%= stan.username %>
  hashed_password: <%= stan.hashed_password %>
  password_salt: <%= stan.password_salt %>
  email: <%= stan.email %>

按照Rails指南,我试图像这样访问它:

class SessionsControllerTest < ActionController::TestCase

  @user = users(:stan)

  # ...

end

我收到此错误:

./test/functional/sessions_controller_test.rb:5: undefined method `users' for SessionsControllerTest:Class (NoMethodError)
    from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'
    from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
    from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/active_support/dependencies.rb:155:in `require'

Answer 1

试试看

fixtures :users

在你的课堂宣言之后

Answer 2

确保你有

fixtures :all

在你的test_helper.rb中

Answer 3

谢谢你的帮助.我意识到我有各种声明和调用结构不正确.这在我引用的指南中没有明确解释,但显然users(:stan)只能在一个should块内部工作,或者在一个test_方法中的纯Test :: Unit中工作.
