title: How can I tell Rails to use RSpec instead of test-unit when creating a new Rails app?
body: <p>I have <code>test-unit</code> installed and <code>rspec</code> installed (along with <code>-core</code>, <code>-expectations</code>, <code>-mocks</code> and <code>-rails</code> version 2.6.x). When I run the command <code>rails new foo</code>, it uses <code>test-unit</code> to generate the test stub files instead of <code>rspec</code>.</p>
  
  <p>Is there an option where I can tell rails to use rspec to generate the tests instead?</p>
