Ruby 堆栈级别太深（SystemStackError）

我有Sinatra应用程序，需要测试我的应用程序

功能/支持/env.rb:

require_relative "../../application"

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

World do
  Capybara.app = Application

  include Capybara::DSL
  include RSpec::Matchers
end

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

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

功能/一个。功能：

require_relative "../../application"

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

World do
  Capybara.app = Application

  include Capybara::DSL
  include RSpec::Matchers
end

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

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

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

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)

嗯，我已经创建了功能/步骤定义/议程步骤。rb:

require_relative "../../application"

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

World do
  Capybara.app = Application

  include Capybara::DSL
  include RSpec::Matchers
end

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

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

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

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)

为什么以及如何修复它

更新：如果我像这样重写我的env.rb，问题就消失了：

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

---

我认为只有

Capybara.app=Application

不应该在

World

中声明，如您的示例所示

下面是我的工作环境.rb：

---

正如您所看到的，RVSWORD类只有包含必要模块的语句。

我得到了相同的“外观相似”错误

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的第一行添加了

require'cucumber/rails'

，它们首先被加载

现在我不再面对这个错误了。

你能发布你的Gemfile.lock或者更多吗？那么你使用的cucumber、capybara和rspec的版本是什么呢？我已经在这里发布了我的Gemfile.lock:@Jacob，rspec用于断言，而capybara只是与web驱动程序对话。说到这里，你肯定需要Rspec和水豚草（可能还需要硒）
