Build Status

Cucumber-Rails brings Cucumber to Rails 3.x. For Rails 2.3.x support, see the rails-2.3.x branch.


Before you can use the generator, add the gem to your project's Gemfile as follows:

group :test do
  gem 'cucumber-rails', :require => false
  # database_cleaner is not required, but highly recommended
  gem 'database_cleaner'

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

Running Cucumber

With Rake:

rake cucumber

Without Rake:

[bundle exec] cucumber

Bugs and feature requests

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
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.

Setting up your environment

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

Running all tests

With all dependencies installed, all specs and features should pass:


One of the features uses MongoDB, which needs to be running in order to make features/mongoid.feature to pass.

Running Appraisal suite

In order to test against multiple versions of key dependencies, the Appraisal is used to generate multiple gemfiles, stored in the gemfiles/ directory. Normally these will only run on Travis; however, if you want to run the full test suite against all gemfiles, run the following commands:

rake gemfiles:install
rake test:all

To run the suite against a named gemfile, use the following:

rake test:gemfile[rails_3_0]

To remove and rebuild the different gemfiles (for example, to update a rails version or its dependencies), use the following:

rake gemfiles:rebuild

Adding dependencies

To support the multiple-gemfile testing, when adding a new dependency the following rules apply:

  1. If it's a runtime dependency of the gem, add it to the gemspec
  2. If it's a primary development dependency, add it to the gemspec
  3. If it's a dependency of a generated rails app in a test, add it to the Gemfile (for local test runs) and each appraisal section (if necessary).

For example, rspec is a primary development dependency, so it lives in the gemspec. By contrast, coffee-rails is a dependency of apps generated with rails 3.1 and 3.2, so lives in the main Gemfile and the rails 3.1 and 3.2 appraisal sections.

Something went wrong with that request. Please try again.
