Guard::Cucumber

travis-ci

Guard::Cucumber allows you to automatically run Cucumber features when files are modified.

Tested on MRI Ruby 1.8.6, 1.8.7, 1.9.2 and the latest versions of JRuby & Rubinius.

Install

Please be sure to have Guard installed before continue.

Install the gem:

gem install guard-cucumber

Add it to your Gemfile, preferably inside the test group:

gem 'guard-cucumber'

Add the default Guard::Cucumber template to your Guardfile by running this command:

guard init cucumber

Usage

Please read the Guard usage documentation.

Guardfile

Guard::Cucumber can be adapted to all kind of projects and comes with a default template that looks like this:

guard 'cucumber' do
  watch(%r{features/.+\.feature})
  watch(%r{features/support/.+})                      { 'features' }
  watch(%r{features/step_definitions/(.+)_steps\.rb}) { |m| Dir[File.join("**/#{m[1]}.feature")][0] || 'features' }
end

Expressed in plain English, this configuration tells Guard::Cucumber:

  1. When a file within the features directory that ends in feature is modified, just run that single feature.
  2. When any file within features/support directory is modified, run all features.
  3. When a file within the features/step_definitions directory that ends in _steps.rb is modified, run the first feature that matches the name (_steps.rb replaced by .feature) and when no feature is found, then run all features.

Please read the Guard documentation for more information about the Guardfile DSL.

Options

You can pass any of the standard Cucumber CLI options using the :cli option:

guard 'cucumber', :cli => '-c --drb --port 1234 --profile guard' do
  ...
end

Former :color, :drb, :port and :profile options are thus deprecated and have no effect anymore.

List of available options

:cli => '--profile guard -c'      # Pass arbitrary Cucumber CLI arguments, 
                                  # default: '--no-profile --color --format progress --strict'

:bundler => false                 # Don't use "bundle exec" to run the Cucumber command
                                  # default: true

:rvm => ['1.8.7', '1.9.2']        # Directly run your features on multiple ruby versions
                                  # default: nil

:notification => false            # Don't display Growl (or Libnotify) notification
                                  # default: true

:all_after_pass => false          # don't run all features after changed features pass
                                  # default: true

:all_on_start => false            # don't run all the features at startup
                                  # default: true

:keep_failed => false             # keep failed features until them pass
                                  # default: true

Cucumber configuration

It's very important that you understand how Cucumber gets configured, because it's often the origin of strange behavior of guard-cucumber.

Cucumber uses cucumber.yml for defining profiles of specific run configurations. When you pass configurations through the :cli option but don't include a specific profile with --profile, then the configurations from the default profile are also used.

For example, when you're using the default cucumber.yml generated by cucumber-rails, then the default profile forces guard-cucumber to always run all features, because it appends the features folder.

Configure Cucumber solely from Guard

If you want to configure Cucumber from Guard solely, then you should pass --no-profile to the :cli option.

Since guard-cucumber version 0.3.2, the default :cli options are:

--no-profile --color --format progress --strict

This default configuration has been chosen to avoid strange behavior when mixing configurations form the cucumber.yml default profile with the guard-cucumber :cli option.

You can safely remove config/cucumber.yml, since all configuration is done in the Guardfile.

Use a separate Guard profile

If you're using different profiles with Cucumber then you should create a profile for Guard in cucumber.yml, something like this:

guard: --format progress --strict --tags ~@wip

Now you want to make guard-cucumber use that profile by passing '--profile guardto the:cli`.

Cucumber with Spork

To use Guard::Cucumber with Spork, you should install Guard::Spork) and use the following configuration:

guard 'spork' do
  watch('config/application.rb')
  watch('config/environment.rb')
  watch(%r{^config/environments/.*\.rb$})
  watch(%r{^config/initializers/.*\.rb$})
  watch('spec/spec_helper.rb')
end

guard 'cucumber', :cli => '--drb --format progress --no-profile' do
  watch(%r{features/.+\.feature})
  watch(%r{features/support/.+})                      { 'features' }
  watch(%r{features/step_definitions/(.+)_steps\.rb}) { |m| Dir[File.join("**/#{ m[1] }.feature")][0] || 'features' }
end
