mysql - FactoryGirl 和 RSpec 不回滚

Question

简单的预先生成的测试不起作用。它已变得更加简单，但测试后数据并未恢复。因此，它第一次运行时通过，然后随着计数的增加而失败。

我在 Mac 上运行，安装了带有 innoDB 引擎的 MariaDb。

rails_helper.rb

RSpec.configure do |config|
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.infer_spec_type_from_file_location!

  config.include Devise::TestHelpers, type: :controller
  config.include FactoryGirl::Syntax::Methods
end

工厂

FactoryGirl.define do
  factory :tag do
    icon
    word
  end
end

FactoryGirl.define do
  factory :word do
    word 'TestWord'
  end
end

FactoryGirl.define do
  factory :icon do
    icon_name "Cool Icon"
    icon_location "cache/1234"
    submission_date "2014-12-15 18:38:20"
  end
end

规范

require 'rails_helper'

RSpec.describe TagsController, type: :controller do

  # let(:tag) {  build(:tag) }
  let(:valid_session) { {} }

  describe "GET #index" do
    it "assigns all tags as @tags" do
      @tag = FactoryGirl.create(:tag)
      get :index, {}, valid_session
      expect(Tag.count).to eq([@tag].count)
    end
  end
 end

您应该使用DataBaseCleaner gem:

在您的 Gemfile 中包含此行:gem 'database_cleaner'，然后运行 ​​bundle install。

然后，将此行包含在 Spec.configure block 中:

config.before(:suite) do
  begin
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with :truncation
    DatabaseCleaner.start
    FactoryGirl.lint
  ensure
    DatabaseCleaner.clean
  end
end

config.before(:each) do
  DatabaseCleaner.start
end

config.after(:each) do
  DatabaseCleaner.clean
end

希望这有帮助:)
