Question

我有Sinatra应用程序，需要测试我的应用程序。

功能性/支撑性/ env.rb：

require_relative "../../application"

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

World do
  Capybara.app = Application

  include Capybara::DSL
  include RSpec::Matchers
end

功能/ 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

测试它：

cucumber features\one.feature

结果：

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

好吧，我创建了 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

测试它：

cucumber features\one.feature

结果：

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)

为什么以及如何解决？

更新：如果我像这样重写我的env.rb，问题就会消失：

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

我得到了相同的外观错误..as

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..

我在 env.rb 的第一行添加require 'cucumber/rails' ...首先加载。

现在不再面对那个错误了。

Answer 2

我认为只有Capybara.app = Application 不应}在World内声明，如您的示例所示。

所以这是我的工作 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

正如您所看到的，RVSWorld类只包含包含必要模块的语句。

堆栈级别太深（SystemStackError）
