导读：当我用spork运行我的rspec测试时,每次我使用capybara的save_and_open_page,spork正在丢失测试套件,或者可能不会输出任何东西… 看日志 # = without save_and_open_page09:04:24 - INFO - Spork server for RSpec,Test::Unit successfully started09:04:24 -

当我用spork运行我的rspec测试时,每次我使用capybara的save_and_open_page,spork正在丢失测试套件,或者可能不会输出任何东西…

看日志

# => without save_and_open_page
09:04:24 - INFO - Spork server for RSpec,Test::Unit successfully started

09:04:24 - INFO - Guard::RSpec is running

[1] guard(main)> Running tests with args ["--drb","spec/features/registration/registration_process_spec.rb"]...
Done.

    # => here i added some errors into my code... still no error message shown...
[1] guard(main)> Running tests with args ["--drb","spec/features/registration/registration_process_spec.rb"]...
Done.

# only works again after restarting spork

有什么建议么？

解决方法

不知何故,您的STDOUT正在被其他缓冲区所取代.所以无论是由水豚写的STDOUT被忽略或消费在别的地方.

尝试以下：

# 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

Capybara的save_and_open_page使用Launchy gem.所以我相信STDOUT和STDERR在这些宝石之一被绊倒了.
