When I try to run rails generate cucumber:feature, I get an error - Could not find generator cucumber:feature.
In my gemfile:
group :test do
gem 'cucumber-rails'
# database_cleaner is not required, but highly recommended
gem 'database_cleaner'
end
The cucumber generate command should looks like
rails generate cucumber:install
after that go to features folder
and create any file name like article_search.feature within write your features ,scenarios
look like as https://github.com/cucumber/cucumber-rails/tree/master/features
for more environment fix
check features/support/env.rb
and for your step definitions go to
features/step_definitions folder
look like this https://github.com/cucumber/cucumber-rails/tree/master/features/step_definitions

Question: Using Rails 5 & Minitest-Rails is there a way to default new Rails apps to default to Spec-style testing?
I teach TDD and it's annoying to have to have the students convert each time we make a new app.
You could create a template.rb file with following configuration:
gem_group :development, :test do
gem "rspec-rails"
end
after_bundle do
`rails g rspec:install`
end
And then build a new Rails project using the following command
rails new my_app -T -m /path/to/template.rb
It will build a new Rails application, add Rails RSpec gem to its Gemfile and execute the install step for RSpec.
Otherwise you could provide a pre-built Rails Git repository and build on top of that.

Looks like you've already done the hard work of answering your question. Though if you're teaching a class with an opinionated group of test gems, and a modified test_helper.rb and a modified application.rb, you may wish to consider writing your own gem that your students can add to their Gemfile. The gem could have the test gems you want as dependencies, and then they can install everything else they need with something like:
bin/rails generate <gem_name>:install
Here's a gem I wrote that you can fork or modify or just use as inspiration.
https://github.com/schadenfred/testable
I actually stole your config code for the above gem, which you can see expressed in inside a generator that lives here:
lib/generators/installer/install_generator.rb
It looks like in config/application.rb you just have to add:
config.generators do |g|
g.test_framework :minitest, spec: true
end
However there's not an automatic way to make Minitest-Rails default to spec style testing.
I could go to rspec, but would rather stay with Minitest for the moment as we teach our students Minitest from the beginning.
Ok so #sonna had 90% of what I was looking for.
I ended up with help creating a .railsrc file with
-d postgresql
-m ~/.template.rb
And a template with:
# .template.rb
# Gems we've talked about in class, but which have absolutely nothing to do
# with setting up spec-style testing.
# Included here for convenience.
gem_group :development do
# Improve the error message you get in the browser
gem 'better_errors'
# Use pry for rails console
gem 'pry-rails'
end
# Add some extra minitest support
gem_group :test do
gem 'minitest-rails'
gem 'minitest-reporters'
end
# Add some code to some files to support spec-style testing
# For these injections, indentation matters!
inject_into_file 'config/application.rb', after: "class Application < Rails::Application\n" do
<<-'RUBY'
# Force new test files to be generated in the minitest-spec style
config.generators do |g|
g.test_framework :minitest, spec: true
end
RUBY
end
# Things to do after all the gems have been installed
after_bundle do
# Run rails generate minitest:install
generate "minitest:install", "--force"
# Add minitest reporters support. This must be run after
# rails generate minitest:install, because that command
# changes test/test_helper.rb
inject_into_file 'test/test_helper.rb', after: 'require "minitest/rails"' do
<<-'RUBY'
require "minitest/reporters" # for Colorized output
# For colorful output!
Minitest::Reporters.use!(
Minitest::Reporters::SpecReporter.new,
ENV,
Minitest.backtrace_filter
)
RUBY
end
end
This sets up my project with postgres for DB, and Minitest-rails using spec-style tests and includes minitest-reporters.
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.
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
I would be appreciated if you could help me in this problem:
I am using rails 3.2.11 and I have already installed
"gem installed scaffold"
I do not know why it is not working for me
main$ rails generate scaffold idea name:string description:text picture:string
It give me this error:
Usage: rails new APP_PATH [options]
generate command is for generating new code. scaffold is a type of generators, it is for generating models, controllers and views in existing application.
To create the project you have to use rails new APP_PATH [options].
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
This is my setup cheat sheet:
In the terminal run the following command:
rails new "app name" --database=postgresql --skip-test-unit
In the gem file add the following:
group :development, :test do
gem "rspec-rails"
gem "factory_girl_rails" `<- only put in test group, not dev`
gem "valid_attribute"
gem "shoulda-matchers"
gem "capybara"
gem "launchy"
gem "simple_form"
gem "pry-rails"
end
group :production do
gem 'rails_12factor'
end
Run ' bundle install ' to install the gems
rails generate rspec:install
rails generate simple_form:install
in spec_helper file require 'capybara/rails'
valid_attribute also needs --> require 'valid_attribute' in the spec_helper.rb file
capybara will need -> require 'spec_helper' in each of the test files in the directory /spec/features/filename_spec.rb
You should see a number of files and directories created for you. The most important of these is the spec directory.
Now you can create models: by tying the model generation process to the creation of the files and directories that RSpec wants, rspec-rails ensures that we have a testing environment that we need.
Add config/database.yml to /.gitignore file
I think you missed to get into your working folder before running the generate scaffold action.
cd "your_app" then run rails generate scaffold idea name:string description:text picture:string
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!
