Couldn't find 'rspec' generator - ruby-on-rails

I'm trying to install RSpec as a gem after having it installed as a plugin. I've gone ahead and followed the directions found here http://github.com/dchelimsky/rspec-rails/wikis for the section titled rspec and rspec-rails gems. When I run ruby script/generate rspec, I get the error Couldn't find 'rspec' generator. Do only the plugins work? If so, why do they even offer the gems for rspec and rspec-rails? I'm running a frozen copy of Rails 2.1.2, and the version of rpsec and rspec-rails I'm using is the newest for today (Nov 7, 2008) 1.1.11.
EDIT Nov 12, 2008
I have both the rspec and rspec-rails gems installed. I've unpacked the gems into the vender/gems folder. Both are version 1.1.11.

Since RSpec has been become the default testing framework in Rails you no longer need to create spec docs via the rspec generators:
Rails 2 RSpec generator
rails generate rspec_model mymodel
Rails 3 RSpec generator
With RSpec as the default testing framework simply use Rails' own generators. This will construct all of the files you need including the RSpec tests. e.g.
$rails generate model mymodel
invoke active_record
create db/migrate/20110531144454_create_mymodels.rb
create app/models/mymodel.rb
invoke rspec
create spec/models/mymodel_spec.rb

Have you installed both rspec and rspec-rails gems?
script/generate rspec
requires rspec-rails gem to be installed.

For Rails 3 and rspec 2+
You must make sure you include 'rspec' and rspec-rails' in your Gemfile
Run Bundle Install
then run rails g rspec:install

If you are using rails 2.3 You need to use
ruby script/plugin install git://github.com/dchelimsky/rspec-rails.git -r 'refs/tags/1.3.3'
and then
ruby script/generate rspec

Is there supposed to be an 'rspec' generator? I've only used the following:
script/generate rspec_model mymodel
script/generate rspec_controller mycontroller

I've had this problem before, it boiled down to the version of RSpec I had not working with the version of Rails I was using. IIRC it was a 2.1 Rails and the updated RSpec hadn't been released as a gem. In fact, 1.1.11 is the gem I have, which would be the latest available (ignoring github gems), so I'm pretty sure that's exactly what my problem was.
I've taken to just using the head of master rspec with whatever version of Rails I happen to be on, it seems stable to me (and isn't going to break things in production, unless somehow a test broke with a false positive).
I do it with git using submodules, for example:
git submodule add git://github.com/dchelimsky/rspec.git vendor/plugins/rspec
git submodule add git://github.com/dchelimsky/rspec-rails.git vendor/plugins/rspec_on_rails

In case anyone is wondering about Rails 3 now,
this seems to do the trick for me:
http://github.com/rspec/rspec-rails/blob/29817932b99fc45adaa93c3f75d503c69aafcaef/README.markdown

I'm using rails 2.3.9. I started of trying to use the gem(s) but just couldn't get the generator for rspec to show up. Then I installed the plugin(s) using the instructions on https://github.com/dchelimsky/rspec/wiki/rails and that did the trick.

On Fedora 9 (OLPC) I did:
$ sudo gem install rspec
$ sudo gem install rspec-rails
Those got me to where I could run
$ ruby script/generate rspec
This worked for me, whereas the git instructions did not work.

If you are using bundler version 1.0.8 you should $ gem update bundler to a newer version 1.0.9.
I had the same symptons and updating bundler helped me out.
Now $ rails g is using gems defined in the Gemfile. Also I grouped my gems like this:
source 'http://rubygems.org'
gem 'rails', '3.0.3'
gem 'sqlite3-ruby', :require => 'sqlite3'
group :test, :development do
gem 'capybara', '0.4.1.1'
gem 'database_cleaner'
gem 'cucumber-rails'
gem 'rspec-rails', '~> 2.4'
gem 'launchy'
end
(Note that test gems are also in the :development group.)
Have a nice day :)

If you type script/rails generate, the only RSpec generator you'll actually see is rspec:install. That's because RSpec is registered with Rails as the test framework, so whenever you generate application components like models, controllers, etc, RSpec specs are generated instead of Test::Unit tests.
Please note that the generators are there to help you get started, but they are no substitute for writing your own examples, and they are only guaranteed to work out of the box for the default scenario (ActiveRecord & Webrat).
https://github.com/rspec/rspec-rails

You might need to run bundle exec :
bundle exec rails g rspec:install

You'll need to do
sudo gem install cucumber-rails

rails plugin vs bundle gem

This two commands seem to generate practically the same thing
rails plugin new __name__
bundle gem __name__
There is a hidden detail I haven't notice?
which one do you use, and basically, why?
Thanks
They can all generate a barebone gem but they are different.
rails plugin new could generate a dummy app inside test, and a basic test_helper, which would be very handy if you want to add some functional/integration tests in gem. You can also revise that a bit to use Rspec. bundle gem would not do that.
If you develop the gem for Rails and need such tests, rails plugin would be better. Otherwise bundle or a gem generating gem jeweller.
Plugins are more or less deprecated in favor of gems in recent versions of Rails.
As far as I can tell, running rails plugin my_gem simply creates a 'my_gem' directory in the root of your rails app.
It's not too much different from running bundle gem my_gem except that it stubs out a couple of test files, and runs bundle install.
This may be useful if you're creating a gem that's made to be run on rails - where you need a "rails environment" (see the test/dummy/app directory).
Still, if you do it this way, it appears the gem is added right into the root of your rails project. You could always move it, but if you were to run bundle gem you could do so wherever you want.

Bootstrap Devise Cancan Rails - Rspec Failure

I just installed Rails3 Bootstrap Device Cancan in my local machine and ran rake spec but I'm getting all test failures with below error in common:
undefined local variable or method 'postgresql_version' for #<ActiveRecord::ConnectionAdaptors::SQLite3Adaptor:0x489dff8>
I'm not sure why I'm getting this since I followed the instructions on https://github.com/RailsApps/rails3-bootstrap-devise-cancan carefully.
I'm currently running this on Windows 8 and used Bitnami RubyStack to run CMD
I ran into the same problem and this is how I resolved it.
It looks like there is a problem with version 1.1.0 of database_cleaner. See "database_cleaner >= 1.1.0 is broken for SQLite" (https://github.com/gregbell/active_admin/issues/2388). I updated my Gemfile to set
gem 'database_cleaner', '< 1.1.0'
then ran "bundle install" and after it completed, "rake spec" ran cleanly.
Double-check your database.yml. Refer to Configuring Rails Applications, Section 3.12, Configuring a Database.
Did you intend to use sqlite3? Is sqlite3 in your Gemfile? Naturally, SQLite3Adaptor will not respond to postgresql_version! Can you include a few more lines of the stack trace?
I doubt this has anything to do with devise or cancan.

Using the turn gem with Test::Unit

I'm using Turn gem in a rails app to colourise my Test::Unit output, and I find the following output before any of my tests run:
stephen#x5:~/code/ruby$ rake test
gem install minitest
gem install minitest
... tests seem to run just fine, and are nicely coloured
This happens everytime I run them. What is the deal here? Am I supposed to be using minitest instead of Test::Unit?
What is the best way to colourise Test::Unit output? Just looking for red and green.
gem 'redgreen' worked great for me (on Ruby 1.9.2 and Rails 3.0.7) with Test::Unit.
Add the above to your Gemfile.
On RubyGems.

Having trouble finding a generator in Rails 3.1 for gem installed using git as source

First, I am using Rails 3.1.
I have installed the activemessaging gem from git.
This is in my Gemfile:
gem 'activemessaging', :git => 'git://github.com/kookster/activemessaging.git'
bundle show activemessaging outputs:
/Users/ken/.rvm/gems/ruby-1.9.2-p180#cMoM/bundler/gems/activemessaging-037532e0eb69
and an ls of .../activemessaging-037532e0eb69 shows
a13g_test_harness filter processor tracer
Yet if I run one of the generators I get a generator not found message. Running rails g does not show any generators for activemessaging.
Does anyone know why these generators are not found?

Rails colour highlighting for the Test::Unit/rake command?

When running test/unit using the rake test command from the terminal within a rails 3 project directory, the test result output is not coloured. Hence, it cannot be interpreted at a glance.
Is there a way of getting colourised output for the results, as you can get in rspec?
>rspec --colour
I discovered that redgreen was abandoned years ago, and found this solution which works well and requires no script hacking. The output, however, shows which test is being run in real time. So it is a lot longer than built in test output. It does have nice colors.
http://rubygems.org/gems/turn
In my Gemfile:
group :test do
gem 'turn'
end
Then run:
$ bundle install
$ rake test
The gem 'turn' works great. The caveat is that it doesn't seem to work with Mocha, due to monkey-patching issues. If you are using Mocha, you can use the redgreen gem. See instructions above in the approved answer for this question.
Yes, you can use the redgreen gem. Include it in your gemfile:
group :development, :test do
gem 'redgreen'
end
And that's all you need for ruby 1.8. If you're using 1.9, there's a workaround. add the test-unit gem:
group :development, :test do
gem 'redgreen'
gem 'test-unit', '1.2.3
end
It's not perfect with 1.9 - test-unit seems to run an empty test suite after every rake task or generator call, which is harmless but annoying.
I am working on Rails 5.1 / minitest and I was also searching for a solution to make the reporting color. None of these test::unit solutions are working, so I googled and saw this solution. Just add the following:
# Gemfile
gem 'minitest-reporters'
# test/test_helper.rb
require "minitest/reporters"
Minitest::Reporters.use!
Github: minitest-reporters
