How can I tell Rails to use RSpec instead of test-unit when creating a new Rails app?

Question

I have test-unit installed and rspec installed (along with -core, -expectations, -mocks and -rails

Answer 1

Create your new rails application as:

rails new  -T

Or remove your test directory from your existing application:

rm -rf test/

Make an entry in your Gemfile:

gem 'rspec-rails'

From the command line install the gem

$ bundle install

From the command line install rspec into your application:

$ rails g rspec:install

Now your rails application uses RSpec instead of test-unit.
