当我用 spork 运行我的 rspec 测试时，每次我使用 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

有什么建议么？

不知何故，你STDOUT被其他一些缓冲区取代了。因此，Capybara 向 STDOUT 写入的任何内容都会在其他地方被忽略或消耗。

尝试以下操作：

# Add global before/after blocks
before :each do
  @old_stdout, @old_stderr = STDOUT, STDERR
end

after :each do
  STDOUT,  STDERR  = @old_stdout, @old_stderr

  # Some gems use $stdout and $stderr, instead of STDOUT and STDERR, replace those too
  $stdout, $stderr = @old_stdout, @old_stderr
end

Capybarasave_and_open_page使用 Launchy gem。因此，我相信STDOUTandSTDERR正在其中一个宝石中被打断。

我在http://blog.mikecordell.com/2013/08/14/guard-and-capybara's-save_and_open_page.html找到了描述问题的真正解决方案。特别感谢此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
