save_and_open_page and spork, spork is loosing test suite / output

[h0jeZvgoxFepBQ2C]

When i run my rspec tests with spork, every time i use capybara's save_and_open_page, spork is loosing the test suite.. or maybe doesnt output anything anymore...

See the log

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

# only works again after restarting spork

Any suggestions?

There are some other people which have the same problem, see:
sporkrb/spork#226 or

If it only happens with Spork, then it isn't an issue with Capybara.

@lichtamberg save_and_open_page uses launchy, and if iirc there were conflicts between spork and launchy at one time. Not sure if those were ever worked out. but those two projects would probably be the best place to start looking

Hmm...

RDX posted following on stackoverflow:

Somehow your STDOUT is getting replaced with some other buffer. So whatever is being written by Capybara to STDOUT is getting ignored or consumed somewhere else.

Try the following:

# 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's save_and_open_page uses Launchy gem. So I believe the STDOUT and STDERR are getting stubbed in one of these gems.

What do you think? its not related to capybara?
