ruby on rails - Don't know how to build task - Cucumber -

in cucumber, seed data loaded via several rake tasks. none of working:

spree::core::engine.load_seed if defined?(spree::core) spree::auth::engine.load_seed if defined?(spree::auth) rake::task['alchemy:db:seed'].invoke 

when run 1 of spree's rake tasks get:

don't know how build task 'db:load_dir' (runtimeerror) 

when run 1 of alchemy's rake tasks get:

don't know how build task 'alchemy:db:seed' (runtimeerror) 

the testing database exists. have ran rake db:test:prepare , appears setup inspections. lets move onto hooks:

# features/support/hooks.rb before   load file.join(rails.root, 'db', 'seeds.rb') end 

this goes root , gets me seed data. decided try this:

# features/support/hooks.rb before   # load file.join(rails.root, 'db', 'seeds.rb')   rake::task['alchemy:db:seed'].invoke end 

the error was:

don't know how build task 'alchemy:db:seed' (runtimeerror) 

i'm unable figure out why rake tasks not working in cucumber.

my gemfile follows:

source 'https://rubygems.org' ruby '2.1.2'  gem 'rails', '4.0.6'  gem 'pg' gem 'redis-rails' gem 'redis-rack-cache'  gem 'sass-rails', '~> 4.0.3' gem 'uglifier', '>= 1.3.0' gem 'coffee-rails', '~> 4.0.0'  gem 'jquery-rails' gem 'turbolinks' gem 'jbuilder', '~> 2.0'  gem 'thin' gem 'durable_decorator_rails', github: 'jumph4x/durable_decorator_rails' gem 'newrelic_rpm' gem 'rake'  gem 'spree', '2.2.2' gem 'spree_gateway', github: 'spree/spree_gateway', branch: '2-2-stable' gem 'spree_auth_devise', github: 'spree/spree_auth_devise', branch: '2-2-stable' gem 'spree_bootstrap_frontend', github: '200creative/spree_bootstrap_frontend', branch: '2-2-stable'  gem 'alchemy_cms', github: 'magiclabs/alchemy_cms' gem 'spree_alchemy', github: 'tesserakt/spree_alchemy'  group :doc   gem 'sdoc', '~> 0.4.0' end  group :development   gem 'better_errors'   gem 'binding_of_caller'   gem 'meta_request' end  group :test   gem 'simplecov', require: false   gem 'cucumber-rails', require: false   gem "cucumber-websteps"   gem 'database_cleaner'   gem "selenium-webdriver"   gem "capybara-webkit" end  group :development, :test   gem "factory_girl_rails", "~> 4.0"   gem "rspec-rails"   gem 'rspec-its'   gem 'shoulda-matchers', require: false end 

and env support file:

# features/support/env.rb require 'cucumber/rails'  actioncontroller::base.allow_rescue = false  begin   databasecleaner.strategy = :transaction rescue nameerror   raise 'you need add database_cleaner your' \    'gemfile (in :test group) if wish use it.' end  cucumber::rails::database.javascript_strategy = :truncation  capybara.register_driver :chrome |app|   capybara::selenium::driver.new(app, browser: :chrome) end  capybara.javascript_driver = :chrome 

it seems test database missing. written in comment above, solution create database , run migrations with

rails_env=test rake db:setup 

happy :)
