Michael Hartl Rails教程(3.2)-第5章Rspec问题 [英] Michael Hartl Rails Tutorial (3.2) - Chapter 5 Rspec issue

问题描述

我已经完成了第5章和所有练习.作为最后练习的一部分，MH让您为ApplicationHelper方法编写测试.

I've completed Chapter 5 and all the exercises. As part of the final exercise, MH has you write tests for the ApplicationHelper method.

完成后，个人测试将通过:

ST2中的
• shift-command-T(使用sublime-text-2-ruby-tests包)
终端中的
• rspec spec/requests/user_pages_spec.rb
终端中的
• rspec spec/requests/static_pages_spec.rb

• shift-command-T in ST2 (using the sublime-text-2-ruby-tests package)
• rspec spec/requests/user_pages_spec.rb in the terminal
• rspec spec/requests/static_pages_spec.rb in the terminal

但是，如果我在终端中使用rspec spec/运行 all 测试，则会出现此错误:

However, if I run all tests with rspec spec/ in the terminal I get this error:

/Users/anonymouscoward/rails/railstut/sample_app/spec/helpers/
application_helper_spec.rb:1:in `<top (required)>': uninitialized
constant ApplicationHelper (NameError)

如果我运行spork并再次尝试，则所有测试均通过.

If I run spork and try rspec spec/ again, all tests pass.

我不确定我为什么会这样工作，或者将来要运行所有测试时是否总是需要运行spork.谢谢.

I'm not sure I understand why this works the way it does, or whether I'll always need to have spork running in the future when I want to run all my tests. Thanks.

推荐答案

我不确定，但是也许您忘记了需要spec_helper. 如果是这样，只需将其插入application_helper_spec.rb

I'm not sure, but maybe you forgot to require spec_helper. If so, just insert this in the first line of application_helper_spec.rb

require 'spec_helper'
