rails4でrspecにfactory_girlを使った時のエラー

rails4でrspecでテストを書こうと思って、factory_girlを使ってみたら
エラー出たのでそのときの対応

まずはバージョンを確認

gem list抜粋
factory_girl (4.4.0)
factory_girl_rails (4.4.1)
rails (4.1.4)
rspec (3.0.0)
rspec-core (3.0.4)
rspec-expectations (3.0.4)
rspec-mocks (3.0.4)
rspec-rails (3.0.2)
rspec-support (3.0.4)

テスト対象のテーブル

mysql> desc seq_sometest4s;
+--------+------------+------+-----+---------+-------+
| Field  | Type       | Null | Key | Default | Extra |
+--------+------------+------+-----+---------+-------+
| id     | int(10)    | NO   | PRI | 0       |       |
| seq_id | bigint(10) | YES  |     | NULL    |       |
+--------+------------+------+-----+---------+-------+

spec_helper.rbにfactory_girlの設定を追加

require 'factory_girl_rails'
RSpec.configure do |config|
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.order = "random"
  config.include FactoryGirl::Syntax::Methods
  config.before do
    FactoryGirl.reload
  end
end

config/application.rbにもfactory_girlの設定を追加

config.generators do |g|
  g.test_framework :rspec, :fixture => true, :fixture_replacement => :factory_girl
  g.fixture_replacement :factory_girl, :dir => 'spec/factories'
end

テストコード

$ cat spec/models/concerns/seq_table_spec.rb 
require 'spec_helper'
 
describe "SeqTable" do
  describe "seq_incrment" do
    FactoryGirl.build(:seq_sometest4)
  end 
end

テストを実行するとエラーになりました。

ちょっとググってみたところ、spec_helper.rbに以下を追加するとよいとあったので入れてみました。

requireの下に
FactoryGirl.find_definitions

そして再度テストを実行してみたところ、またエラーが出ました。

ちょっと原因がわからなかったので、railsコマンドでもう一度modelを作ってみました。
specファイルの中身を見ると、requireの記述が違います。

$ bundle exec rails g model seq_sometest4 id:integer seq_id:integer
      invoke  active_record
      create    db/migrate/20140827015707_create_seq_sometest4s.rb
   identical    app/models/seq_sometest4.rb
      invoke    rspec
      create      spec/models/seq_sometest4_spec.rb
      invoke      factory_girl
   identical        spec/factories/seq_sometest4s.rb
 
$ cat spec/models/seq_sometest4_spec.rb 
require 'rails_helper'
 
RSpec.describe SeqSometest4, :type => :model do
  pending "add some examples to (or delete) #{__FILE__}"
end

require 'rails_helper'に変更して再度テストを実行してみましたが、またエラーになりました。。

先ほど付け足したspec_helper.rbのFactoryGirl.find_definitionsを削除して再度実行したら、
今度はエラーにならずに動きました。
テスト自体は書いてないので0件です。

$ bundle exec rspec spec/models/concerns/seq_table_spec.rb
No examples found.
 
Finished in 0.00033 seconds (files took 3.61 seconds to load)
0 examples, 0 failures

require 'rails_helper'が肝だった訳ですが、ちゃんとrailsコマンドで最初から作っていれば
エラーにはまらずに済んでたと思うので、あるものはちゃんと使わないといけないですね。
