テストが通らない件

rake test:units だと通らず、test ファイルを直接指定すると通る、という状態。

rake test:units だと

C:\Work\drweb_office>rake test:units

で、単独で実行すると

と 0F0E になります。

以前にも同様の問題に遭遇したことがあった気がするけど思い出せない --;)。なんだろうなぁ...

モデルはこんな感じ。

class DistributorStaff < ActiveRecord::Base
  acts_as_list :scope => :distributor_id
  
  belongs_to :distributor

  ROLE = [['販売', 1],  ['経理', 2],  ['技術', 3],  ['その他', 9]].freeze

  [:distributor_id, :role, :name, :name_in_kana, :email].each do |key|
    validates_presence_of(key, :message => 'は必須項目です。')
  end
  validates_format_of(:email, :with => /^[-\.\w]{1,}@([-\w]{1,}\.){1,}([-\w]{1,})$/, :message => 'の書式が正しくありません。')

  validates_inclusion_of(:role, :in => ROLE.map {|role| role[1]}, :message => 'が不正です。')
  validates_inclusion_of(:distributor_id, :in => Distributor.find(:all, :select => 'id').collect {|db| db.id}, :message => "が不正です。")
end

あまり悩んでいても仕方ないから、先に進むかな...
