Question

我正在尝试编写测试，保存公司对象。但是，公司对象未保存，并且表中没有公司记录。为什么以及如何解决问题？

分贝/ schema.rb

ActiveRecord::Schema.define(version: 20140626075006) do
  create_table "companies", force: true do |t|
    t.string   "name"
    t.datetime "created_at"
    t.datetime "updated_at"
  end
end

应用程序/模型/ company.rb

class Company < ActiveRecord::Base
end

规格/工厂/ companies.rb

FactoryGirl.define do
  factory :company do
    name "MyString"
  end
end

规格/模型/ company_spec.rb

require 'spec_helper'

describe Company do
  let(:company) { FactoryGirl.create(:company) }
  context "test context"do
    it "test" do
      Company.first.name
    end
  end
end

规格/ spec_helper.rb

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
RSpec.configure do |config|
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.infer_base_class_for_anonymous_controllers = false
  config.order = "random"
end

结果

/Users/machidahiroaki/.rvm/rubies/ruby-2.0.0-p451/bin/ruby -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) /Users/machidahiroaki/RubymineProjects/rspec_sample/bin/rake spec

啊，被这几次烧了。

let表达式被懒惰地评估。你没有引用那个，所以company永远不会被创建。例如，您可以使用let!。

  let!(:company) { FactoryGirl.create(:company) }

或引用company

let(:company) { FactoryGirl.create(:company) }
context "test context"do
  it "test" do
    expect(company).to_not be_nil
    expect(Company.count).to eq 1
  end
end

FactoryGirl记录未保存
