Rails4 Rake : 테스트 오류

Question

최근 업데이트 테스트가 작동하지 않는 경우. Ruby 2.0.0-p0, 레일즈 4.0.0beta1, 몽고이드 4.0.0.

/Users/doniv/.rvm/gems/ruby-2.0.0-p0@global/gems/rake-10.0.3/lib/rake/task_manager.rb:49:in `[]': Don't know how to build task 'db:test:load' (RuntimeError) 
from /Users/doniv/.rvm/gems/ruby-2.0.0-p0@global/gems/rake-10.0.3/lib/rake/task.rb:321:in `[]'

from /Users/doniv/.rvm/gems/ruby-2.0.0-p0/bundler/gems/rails-f0d5e32f891d/railties/lib/rails/commands/test_runner.rb:18:in `new'

from bin/rails:4:in `require' 
from bin/rails:4:in `<main>' 

어떤 생각?

감사합니다.

잘못된 :

gem 'rails', '~> 4.0.0.beta', :git => 'git://github.com/rails/rails.git' 
... 
gem 'sass-rails', '~> 4.0.0.beta', :git => 'git://github.com/rails/sass-rails.git' 
gem 'coffee-rails', '~> 4.0.0.beta', :git => 'git://github.com/rails/coffee-rails.git' 

유효한 :

gem 'rails', '~> 4.0.0.beta' 
... 
gem 'sass-rails', '~> 4.0.0.beta' 
gem 'coffee-rails', '~> 4.0.0.beta'
