Ruby on Rails: Switch from test_unit to rspec

ruby-on-rails rspec gem testunit

I'm going through a tutorial that has suggested using rspec, but I have already gone through a lot of default rails installation. I really don't want to have to redo the installation at all. Anyway, when I run

$ rails g integration_test named

I get

  invoke  test_unit
  create    test/integration/named_test.rb

When I run bundle, various rspec gems are listed, but test_unit is not. The tutorial seems to have rails invoke rspec instead of test_unit without doing anything additional. How do I get rails to use rspec with the integration test generator command?

In your config/application.rb file :

config.generators do |g|
  g.test_framework :rspec
end

Now when you run your generators (example rails generate scaffold post), you get rspec test files. Remember to restart your server. For more information on generators see:

RailsCasts #216 Generators in Rails 3

If you really want to use the integration_test generator you'll need to specifically modify the command:

rails g integration_test named --integration-tool=rspec
