关于ruby on rails：save_and_open_page和spork，spork失去了测试套件/输出


save_and_open_page and spork, spork is loosing test suite / output

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都失去了测试套件..或者也许不再输出任何内容了。

有什么建议吗？

以某种方式将您的STDOUT替换为其他缓冲区。因此，水豚写到STDOUT的任何内容都会被忽略或在其他地方使用。

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

水豚的save_and_open_page使用Launchyruby。因此，我相信STDOUT和STDERR会被这些ruby之一卡住。

我在http://blog.mikecordell.com/2013/08/14/guard-and-capybara's-save_and_open_page.html上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
