Feature: DRb Server Integration
To prevent waiting for Rails and other large Ruby applications to load their environments
for each feature run Cucumber ships with a DRb client that can speak to a server which
loads up the environment only once.
Background: App with Spork support
Spork is a gem that has a DRb server and the scenarios below illustrate how to use it.
However, any DRb server that adheres to the protocol that the client expects would work.
Given a standard Cucumber project directory structure
And a file named "features/support/env.rb" with:
"""
require 'rubygems'
require 'spork'
Spork.prefork do
puts "I'm loading all the heavy stuff..."
end
Spork.each_run do
puts "I'm loading the stuff just for this run..."
end
"""
And a file named "features/sample.feature" with:
"""
# language: en
Feature: Sample
Scenario: this is a test
Given I am just testing stuff
"""
And a file named "features/essai.feature" with:
"""
# language: fr
Fonctionnalité: Essai
Scenario: ceci est un test
Soit je teste
"""
And a file named "features/step_definitions/all_your_steps_are_belong_to_us.rb" with:
"""
Given /^I am just testing stuff$/ do
# no-op
end
Soit /^je teste$/ do
# no-op
end
"""
Scenario: Feature Passing with --drb flag
Given I am running spork in the background
When I run cucumber features --drb
Then it should pass
And STDERR should be empty
And the output should contain
"""
1 step (1 passed)
"""
And the output should contain
"""
I'm loading the stuff just for this run...
"""
And the output should not contain
"""
I'm loading all the heavy stuff...
"""
Scenario: Feature Failing with --drb flag
Given a file named "features/step_definitions/all_your_steps_are_belong_to_us.rb" with:
"""
Given /^I am just testing stuff$/ do
raise "Oh noes!"
end
"""
And I am running spork in the background
When I run cucumber features --drb
Then it should fail
And the output should contain
"""
1 step (1 failed)

And the output should contain
"""
I'm loading the stuff just for this run...
"""
And the output should not contain
"""
I'm loading all the heavy stuff...
"""
Scenario: Feature Run with --drb flag with no DRb server running
Cucumber will fall back on running the features locally in this case.
Given I am not running a DRb server in the background
When I run cucumber features --drb
Then it should pass
