Rails3集成测试插件Rails-Carrot(二)

 

本篇简要介绍使用JRuby + RSpec + Rails-Carrot + Celerity 进行rails3项目的集成测试。

 

 

1. Install jruby

> rvm install jruby

2. Rails Gemfile

if defined?(JRUBY_VERSION)

  gem 'activerecord-jdbc-adapter', '1.0.2'

  gem 'jdbc-mysql', :require => false

  gem 'celerity'

  gem 'rails-carrot', :require => 'carrot'

else

  gem 'mysql2'

  group :celerity do # celerity 是项目测试环境，根据喜好自己修改

    gem 'mysql'

  end

end

Other test gems

group :development, :test do

  gem "database_cleaner"

  gem 'webrat'

  gem "rspec", ">= 2.0.0"

  gem "rspec-rails", ">= 2.0.0"

end

3. Add Rails Environment 

database.yml

celerity:

  adapter: mysql

  encoding: utf8

  reconnect: false

  database: AC_rails3_celerity

  pool: 5

  username: root

  password:

  socket: /var/run/mysqld/mysqld.sock

#{Rails.root}/config/environments/celerity.rb

ACRails3::Application.configure do

  config.cache_classes = true

  config.whiny_nils = true

  config.consider_all_requests_local       = true

  config.action_controller.perform_caching = false

  config.action_dispatch.show_exceptions = false

  config.action_mailer.delivery_method = :test

  config.active_support.deprecation = :stderr

end

4. Install Gems

>rvm jruby

>bundle install

5. RSpec helper

Create a RSpec helper and you can use it to test with Celerity.

#{Rails.root}/spec/Celerity_helper

require 'database_cleaner' 

require 'celerity'

require 'carrot'

ENV["RAILS_ENV"] = 'celerity'

require File.expand_path("../../config/environment", __FILE__)

require 'rspec/rails'

Carrot.configure do |config|

  config.run_server = true

  config.external_ruby = true

  config.rails_command = "~/.rvm/gems/ruby-1.9.2-p0/bin/rails s -e celerity -p 3001"

  config.project_path = "#{Rails.root}"

  config.server_port = 3001

  # config.server_debug = true

end

Carrot.register_driver(Celerity::Browser.new)

RSpec.configure do |config|

   DatabaseCleaner.strategy = :truncation 

 

   config.before :each do 

     @browser = Carrot.driver 

     DatabaseCleaner.clean 

   end

   config.after :all do

     DatabaseCleaner.clean 

   end

 

   config.use_transactional_fixtures = false

  def url(path)

    Carrot.url(path)

  end

  def login(browser, login, password) 

     browser.text_field(:name, 'login').value = login

     browser.text_field(:name, 'password').value = password 

     browser.button(:name, 'commit').click 

  end 

end

6. Example

#{Rails.root}/spec/requests/hello_spec.rb

require 'celerity_helper'

describe "QA" do

 

  before do

     #以下为业务数据，直接插入数据到数据库

     @company = create_company 

     @user = create_company_admin(@company, {:login => "qaman", :email => "[e-mail]"}) 

  end

  it "should redirect to main page" do

       @browser.goto(url('/'))

       login(@browser, @user.login, "123456") 

      @browser.text.should =~ /Projects of Shepherd/

  end

end
