hunt for the bug

Spent three days last week hunting for mysterious bug which caused factory_girl factories randomly fail with ‘Trait not registered: class’ message during full test suite run. When you run all controller or model tests separately - everything was fine and all tests which were failing during full run worked perfectly.

At first I ignored this issue - I had just added two new factories, which coincidentally used ‘class’ parameter in their definition to specify generated class explicitly, and I needed these factories to develop code I was working on and I thought that I’ll fix or just remove these factories later.

But as it usually happens it was not as simple as I thought. Suddenly I discovered that tests started failing with the same symptoms on common ‘develop’ branch and not only on topic branch. And I broke tests already in two other places, so cleanup was really needed.

First two days I spent trying to find out what happening in factory_girl internals using old-school print logging and later pry-debugger but without much success except that I was able to locate single spec file in ./spec/workers/ which caused failure of all consecutive factory calls. Then I started looking at git history, trying to find commit which introduced this issue. Luckily, in spite of heavy rebasing and few backported commits, my ‘master’ branch didn't have this issue and I was able to pinpoint this to single commit. At first glance this commit looked almost innocent - it just extracted code from model and moved it to app/worker/ directory. But there were two tests added to failing spec file and they were the tests which caused cascading failure of all remaining factories in suite. After reviewing the code under test I had found that real culprit was memory leak debugging code I quickly slapped into 'master' without running tests:

counts = Hash.new { 0 }

ObjectSpace.each_object do |o|

  counts[o.class] += 1

end

counts.reject! { |_k, v| v < 100 }

It seems that FactoryGirl::DefinitionsProxy undefines all methods including class and method_missing in this class adds any calls as traits to factory so walking through ObjectSpace and calling class on every object wreaks havoc on factories.

Configuring Factory Girl Correctly

Factory Girl is a great fixture replacement from thoughtbot. However, sometimes a portion of ugliness might spoil the picture e.g. when the gem is not correctly setup with Bundler (at least in Rails 2.3). A typical gem 'factory_girl' setup seems to be working fine but only until You run some database related tasks such as rake db:reset RAILS_ENV=test. Here's what You might end up with :

Mysql::Error: Table 'SomeApp_test.users' doesn't exist: SHOW FIELDS FROM `users`

This is being caused by the gem initialization hook for Rails, executing Factory.find_definitions while the database is in an inconsistent state. Seems we'll need to get back to the good old days of require it yourself. But adding a require 'factory_girl' in a test helper is not enough. We need to make sure that the factory definitions are resolved (the initializaiton hook might not execute as the Rails.configuration probably already finished initializing while we're loading factory_girl from a test_helper) : embedGist('646529.js');

Rspec helper to add find_or_create to FactoryGirl

Helper for FactoryGirl to allow for find_or_create

Make sure to include the helper in your spec_helper.rb

config.include FactoryGirlHelper

Now in your specs, you can simply:

role = find_or_create(:role, name: 'Admin')

Testosterone: why I like using the FactoryGirl full namespace

I think hiding the FactoryGirl namespace by including FactoryGirl::Syntax::Methods to make typing easier is also making it easier for bad habits to sneak into your tests.

If you find you are typing FactoryGirl.create too much it is a hint/smell that you might be doing something wrong.

Maybe organizing your create/build calls into a better :before or :all strategy will help

The moral: Tests need refactoring love just like your application code

FactoryGirlでファイルアップロードを偽装する

# coding: utf-8 include ActionDispatch::TestProcess FactoryGirl.define do factory :user do name { Faker::Name.name } avatar { fixture_file_upload Rails.root.join('spec', 'fixtures', 'avatar.png'), 'image/png' } end end

っていう風にすると良い。

こうすることで、avatar.pngをアップロードした状態のUserを生成できる。

最初ActionDispatch::TestProcessをincludeし忘れてて、「なんで動かないんじゃこいつ」ってなってたので、多分他にも困ってる人いるんじゃないかなぁ。

と思ってたら↓こういうやり方もあるらしい。

便利だなぁ。やり方を公式が載せてくれてるのは大変ありがたいことです。

paperclip なmodelでattachmentをテストする (factory_girl編)

paperclip はとっても簡単にmodelに添付ファイルを付けるための Gem です。

class User < ActiveRecord::Base attr_accessible :avatar has_attached_file :avatar, :styles => { :medium => "300x300>", :thumb => "100x100>" } end

なんてことをすると、Userに avatar という名前でプロフィール画像を付けることができます。

ちなみにこの例では、medium, thumb を指定することにより、アップロードされた添付ファイル以外に 300x300, 100x100 の画像を自動生成するようになっています。

このモデルの添付ファイルをテストしたい時は、 fixture_file_upload を使います。

spec/factories/users.rb

include ActionDispatch::TestProcess # この行を追加 FactoryGirl.define do factory :user do name # avatar にfixture_file_upload で添付ファイルを追加 avatar { fixture_file_upload([Rails.root, "public", "images", "bag1_1.jpg"].join("/"), "image/jpg") } end end
