Rails colour highlighting for the Test::Unit/rake command? - ruby-on-rails

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

rails swtiching to rspec from default test unit

I have a rails 4 app. I have no tests at the moment, but when I created the app I didn't skip the default test unit so there are some empty test files (and other default settings) in my app.
Now I would like to use rspec + capybara, but don't know what the necessary extra steps are to properly install those and make sure the testing will work fine. I saw some answers on stackoverflow but thoose were pretty old.
As far as I know the installation looks like this if test unit is skipped on creation:
group :development, :test do
gem 'rspec-rails'
end
group :test do
gem 'capybara'
end
then
rails g rspec:install
Can sby tell me what the extra steps are?

Follow these steps:
add code to your_app/config/application.rb file:
config.generators do |g|
g.test_framework :rspec
end
add below code to your_app's Gemfile:
group :test, :development do
gem 'rspec-rails'
end
save it, and run bundle install to install rspec gem
Initialize the spec/ directory
rails generate rspec:install
Use the rspec command to run your specs:
bundle exec rspec
Hopefully it helps.

Where is rails_helper.rb file?

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,
Otterman

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

Rails 3.2 can't find my tests, thinks they are in "test" directory

I am trying to user RSpec and failing to configure MiniTest/Spork/Capybara/Guard. My Gemfile is all set and I ran the command to install RSpec.
Unfortunately, the application continues to "think" my tests are in the test directory. Sorry, they're not. They're in specs, and the framework should really know that.
Maybe it's some sort of configuration issue from trying to get the impossible stack above to work that I still have in place. Where does Rails "decide" in which directory to look for tests? RSpec itself is the one that created the spec directory.

This is how rspec-rails should be included in your Gemfile.
group :development, :test do
gem 'rspec-rails', '2.11.0'
end
Make sure it is added in both :development and :test group.

Problems with Ruby versions

I am learning Ruby and have to do some homework, but have problem with executing code. I searched this forum and Google and found that this could be problem with different Ruby versions but I don't know how to fix this. I've tried to execute:
cucumber features/filter_movie_list.feature
and got this:
And I should not see 'G' #
features/step_definitions/movie_steps.rb:32
no such file to load -- rspec/matchers/built_in/has (LoadError)
./features/step_definitions/movie_steps.rb:34:in /^(?:|I )should not see '([^']*)'$/'
features/filter_movie_list.feature:37:inAnd I should not see 'G''
Can someone help me to solve this problem or give me link to solution?
EDIT:
movie_steps.rb relevant for this taks is:
Then /^(?:|I )should not see '([^']*)'$/ do |text|
if page.respond_to? :should
page.find('#movies').should have_no_content(text)
else
assert page.find('#movies').has_no_content?(text)
end
end

The error message says that Cucumber can't find RSpec.
To solve it, edit your Gemfile and add these and that should solve it.
group :test do
gem 'rspec' # Behavior Driven Development (BDD) for Ruby
gem 'rspec-core' # RSpec runner and example groups.
gem 'rspec-expectations' # RSpec matchers for should and should_not.
gem 'rspec-mocks' # RSpec test double framework with stubbing and mocking.
gem 'rspec-rails' # RSpec version 2.x for Rails version 3.x.
end
If that does solve it, you can probably remove all those lines except the first one (the 'rspec' one) because that line should take care of the others.

Couldn't find 'rspec' generator

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
