当我使用shoulda时,“rake测试”为什么运行空套件?

这是我的测试套件:

class ReleaseTest < ActiveSupport::TestCase
  should_not_allow_values_for :title, '', 'blah', 'blah  blah'
  should_allow_values_for :title, 'blah - bleh', 'blah blah - bleh bleh'
  def test_something
    assert true
  end
end

宏应该生成5个测试,然后 test_something 下面(只是看看这是否重要),总共6个测试。它们都通过了,正如您在下面看到的,但是它运行一个0测试套件。即使我完全清空了,也会发生这种情况 ReleaseTest . 这个问题只有在我 config.gem 'shoulda' 在我的 environment.rb . 如果我明确这么做 require 'shoulda' 在我的测试中,一切都很好。这是什么原因造成的?
