Stackebene zu tief (SystemStackError)

Question

Ich habe Sinatra Anwendung und müssen meine Anwendung zu testen.

features/support/env.rb:

require_relative "../../application"

require "capybara"
require "capybara/cucumber"
require "rspec"

World do
  Capybara.app = Application

  include Capybara::DSL
  include RSpec::Matchers
end

features/one.feature:

Feature: Test homepage
  In order to make sure people can open my site
  I want to check it opened

  Scenario: Opening first page
    Given I have opened homepage    
    Then I should see site header

Testen Sie es:

cucumber features\one.feature

Ergebnis:

Feature: Test homepage
  In order to make sure people can open my site
  I want to check it opened

  Scenario: Opening first page    # features\one.feature:5
    Given I have opened homepage  # features\one.feature:6
    Then I should see site header # features\one.feature:7

1 scenario (1 undefined)
2 steps (2 undefined)
0m0.006s

You can implement step definitions for undefined steps with these snippets:

Given /^I have opened homepage$/ do
  pending # express the regexp above with the code you wish you had
end

Then /^I should see site header$/ do
  pending # express the regexp above with the code you wish you had
end

Nun, ich habe eine features/step_definitions/agenda_steps.rb:

Given /^I have opened homepage$/ do
  pending # express the regexp above with the code you wish you had
end

Then /^I should see site header$/ do
  pending # express the regexp above with the code you wish you had
end

Testen Sie es:

cucumber features\one.feature

Ergebnis:

Feature: Test homepage
  In order to make sure people can open my site
  I want to check it opened

  Scenario: Opening first page    # features\one.feature:5
    Given I have opened homepage  # features/step_definitions/agenda_steps.rb:1
C:/Ruby193/bin/cucumber:19: stack level too deep (SystemStackError)

Warum und wie kann ich das beheben?

Aktualisiert: Das Problem ist verschwunden, wenn ich meine env.rb wie folgt umschreibe:

require_relative "../../application"

require "capybara"
require "capybara/cucumber"
require "rspec"

Capybara.app = Application
#World do
#  Capybara.app = Application
# 
#  include Capybara::DSL
#  include RSpec::Matchers
#end

Answer 1

Ich habe den gleichen Fehler erhalten wie

stack level too deep (SystemStackError)
/usr/local/rvm/gems/ruby-1.9.2-p290/gems/cucumber-1.1.4/lib/cucumber/core_ext/instance_exec.rb:73..

i hinzugefügt require 'cucumber/rails' en erste Zeile von env.rb ...die zuerst geladen werden.

Jetzt habe ich diesen Fehler nicht mehr.

Answer 2

Ich glaube, dass nur Capybara.app = Application sollte nicht innerhalb von World wie in Ihrem Beispiel gezeigt.

So funktioniert meine env.rb :

ENV['RACK_ENV'] = 'test'
require File.join(File.dirname(__FILE__), '..', '..', 'rvs.rb')

require 'capybara'
require 'capybara/cucumber'
require 'rspec'
require 'r18n-core'

Capybara.app = RVS

class RVSWorld
  include R18n::Helpers
  include Capybara::DSL
  include RSpec::Expectations
  include RSpec::Matchers
end

World do
  RVSWorld.new
end

Wie Sie sehen können, enthält die Klasse RVSWorld nur Anweisungen, die die notwendigen Module enthalten.
