save_and_open_page e spork, spork sta perdendo suite di test/uscita

Question

quando ho eseguito i miei test RSpec con Spork, ogni volta che uso save_and_open_page di capibara, spork sta perdendo la suite di test .. o forse pretende di uscita più niente ...

Vedi il registro

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

# only works again after restarting spork 

Qualche suggerimento?

Answer 1

In qualche modo il tuo STDOUT viene sostituito con un altro buffer. Quindi tutto ciò che viene scritto da Capybara a STDOUT viene ignorato o consumato altrove.

provare quanto segue:

# 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 di save_and_open_page usa Launchy gioiello. Quindi credo che lo STDOUT e lo STDERR vengano stubati in una di queste gemme.

Ho trovato la soluzione reale per il problema descritto a http://blog.mikecordell.com/2013/08/14/guard-and-capybara's-save_and_open_page.html. Un ringraziamento speciale all'autore di questa soluzione.

Basta aggiungere:

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
