save_and_open_page和spork,spork正在失去测试套件/输出

Question

当我使用spork运行我的rspec测试时,每次使用capybara的save_and_open_page时,spork都会丢失测试套件..或者可能不再输出任何东西......

查看日志

# => without save_and_open_page

# only works again after restarting spork

有什么建议？

我在http://blog.mikecordell.com/2013/08/14/guard-and-capybara's-save_and_open_page.html找到了所描述问题的真正解决方案。特别感谢该解决方案的实际作者。

只需添加：

RSpec.configure do |config|
  config.before(:each) do
    @old_stdout, @old_stderr = STDOUT, STDERR
  end

  config.after(:each) do
    $stdout, $stderr = @old_stdout, @old_stderr
  end
end

到spec_helper.rb
