I am currently following this tutorial to begin testing rspec with capybara and selenium. I included the necessary gems and ran a bundle install, but cant seem to find the rails_helper.rb to continue with the tutorial.
This is on rails 4.2.4.
Thanks,

rails_helper.rb in generated when you run rails g rspec:install. Make sure you are using a relatively recent version of rspec-rails as versions before 3.0 only the spec_helper.rb is used configure the test suite (well by default at least).
The spec_helper.rb file is used to set up RSpec itself and rails_helper.rb sets up the rails stack.
You should be able to find the file in ../spec/rails_helper
As mentioned, I was missing
group :development, :test do
gem 'rspec-rails', '~> 3.0'
end
in my gemfile.
After which I ran
rails generate rspec:install
I'm using Ruby 2.2.0p0, and Rails 4.2.0. The Rails application is currently defaulting to using minitest, even though there's no testing gems mentioned in the Gemfile. For example, I have rake test in my rake tasks, and a test folder.
I can see how to install RSpec-rails. But what, if anything, do I need to do to uninstall minitest?
The only thing the RSpec-Rails README has is
Once installed, RSpec will generate spec files instead of Test::Unit
test files when commands like rails generate model and rails generate
controller are used.
It seems to me that in your case it not necessary to uninstall minitest, just add rspec to your Gemfile and start using it. However I recommend you to make RSpec as your default test framework.
Just add to config/application.rb next line:
config.generators.test_framework :rspec
That's it. Now Rails knows that you use RSpec and when you use Rails generators, it will add appropriate RSpec templete files, not Minitest ones. If you have test folder in your application (it's used by Minitest and Test::Unit) you can delete it now.
I try to use Capybara with rspec. I have installed version 1.1.2.
rails generate integration_test application
Unfortunately this is invoking test_unit and generates files in test instead of spec. How could I change it?
The generators should generate specs rather than test_unit tests if you have the rspec-rails gem in your development group in your Gemfile, e.g.:
group :test, :development do
gem "rspec-rails"
end
I am using RSpec, but Rails insists on generating Test::Unit tests. Maybe there is a configuration I missed?
if you are using rails 2 then you do:
ruby script/generate rspec_model Foo
using Rails 3 check out this example:
http://paulbarry.com/articles/2010/01/13/customizing-generators-in-rails-3
If you're using Rails 3, you need the rspec-rails integration gem from github: https://github.com/rspec/rspec-rails
The instructions are there on Github, but you will need to run
script/rails generate rspec:install
From the README:
"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."
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
