Cucumber-Rails brings Cucumber to Rails 3.x. For Rails 2x support, see the Cucumber Wiki.
Before you can use the generator, add the gem to your project's Gemfile as follows:
group :test do
gem 'cucumber-rails'
# database_cleaner is not required, but highly recommended
gem 'database_cleaner'
end
Then install it by running:
bundle install
Learn about the various options:
rails generate cucumber:install --help
Finally, bootstrap your Rails app, for example:
rails generate cucumber:install
With Rake:
rake cucumber
Without Rake:
[bundle exec] cucumber
The only way to have a bug fixed or a new feature accepted is to describe it with a Cucumber feature. Let's say you think you have found a bug in the cucumber:install generator. Fork this project, clone it to your workstation and check out a branch with a descriptive name:
git clone [email protected]:you/cucumber-rails.git
git checkout -b bug-install-generator
Start by making sure you can run the existing features. Now, create a feature that demonstrates what's wrong. See the existing features for examples. When you have a failing feature that reproduces the bug, commit, push and send a pull request. Someone from the Cucumber-Rails team will review it and hopefully create a fix.
If you know how to fix the bug yourself, make a second commit (after committing the failing feature) before you send the pull request.
I strongly recommend rvm and ruby 1.9.3. When you have that, cd into your cucumber-rails repository and:
gem install bundler
bundle install
With all dependencies installed, all features should pass:
rake cucumber
One of the features uses MongoDB, which needs to be running in order to make features/mongoid.feature to pass.
