LoadError when called rake task with RAILS_ENV=test

Question

I am using Ruby 2.1.1 and rails-4.1.0 with Spring.

I cannot launch rake with RAILS_ENV=test attribute. For some reasons rake command

RAILS_ENV=test rake db:migrate

lead to the following error:

/home/user/.rvm/gems/ruby-2.1.1/gems/activesupport-4.1.0/lib/active_support/dependencies.rb:241:in `load': cannot load such file -- /home/user/rbpr/getLead/db:migrate (LoadError)

    from /home/user/.rvm/gems/ruby-2.1.1/gems/rspec-core-2.14.8/lib/rspec/core/runner.rb:17:in `block in autorun'

My Rakfefile was not changed, it is default:

require File.expand_path('../config/application', __FILE__)
GetLead::Application.load_tasks

With RAILS_ENV=development and RAILS_ENV=production I have no LoadErrors. How can I catch this bug?

UPDATE

I have installed test DB and I have no pending migrations (all migrations are in status up for RAILS_ENV=test).

test:
  adapter: postgresql
  encoding: unicode
  database: pgdb_getlead_test
  pool: 15
  username: ***
  password: ***

I have update RSpec, but still have the same error:

The same with rake db:test:prepare:

Here is source code where this error occurred

FINAL UPDATE

The problem was with the Gemfile and gems for testing in development group, many thanks for your attention.

Answer 1

The issue is with the Gemfile and the grouping of certain gems to also load in development environment. If they're testing gems, keep them in group :test unless absolutely necessary to move them to development, like factory_gril_rails in example. So having,

group :test do
  gem 'rspec'
  gem 'rspec-rails', '~> 3.0.0.beta'
  ...

instead of:

group :development, :test do 
  gem 'rspec'
  ...

worked for me on my machine cloning your project. Hope this helps, give it a try.

p.s: there is also an old issue reported earlier here.

Also, I think you'll not have to require factory_girl_rails in you Gemfile like:

gem 'factory_girl_rails', require: false 

And then require it in your spec_helper:

require 'factory_girl_rails'

This way you're using this gem but you don't need to require it in other places than spec_helper.rb

Answer 2

Look at the error message, it says

WARNING: db:test:prepare is deprecated. The Rails test helper now maintains your test schema automatically, see the release notes for details.

In Rails 4.1+, they deprecated db:test:prepare with that message
