ruby-on-rails - 当我进行测试时，test_helper 不加载

Question

我需要对模型进行测试，但是当我这样做时:

ruby test/unit/user_test.rb 

我也试过其他方法:

ruby -I test test/unit/user_test.rb
rake test:units TEST=test/unit/user_test.rb

但是任何人做测试都说:

test/unit/user_test.rb:1:in `require': no such file to load -- test_helper (LoadError)

或者喜欢。

这是部分代码(只是开头):

require 'test_helper'

class UserTest < Test::Unit::TestCase
  self.use_instantiated_fixtures  = true
  fixtures :users

  def test_auth 
    #check that we can login we a valid user 
    assert_equal  @bob, User.authenticate("bob", "test")    
    #wrong username
    assert_nil    User.authenticate("nonbob", "test")
    #wrong password
    assert_nil    User.authenticate("bob", "wrongpass")
    #wrong login and pass
    assert_nil    User.authenticate("nonbob", "wrongpass")
  end

此致

试试这个要求:

require File.dirname(__FILE__) + '/../test_helper'
