Class Method Details



  

    .autorun  
  



  

    
  

    Note:
    


This is not generally needed. The ‘rspec` command takes care of running examples for you without involving an at_exit hook. This is only needed if you are running specs using the ruby command, and even then, the normal way to invoke this is by requiring rspec/autorun.



  




Register an ‘at_exit` hook that runs the suite when the process exits.

# File 'rspec-core/lib/rspec/core/runner.rb', line 16



def self.autorun
  if autorun_disabled?
    RSpec.deprecate("Requiring `rspec/autorun` when running RSpec via the `rspec` command")
    return
  elsif installed_at_exit? || running_in_drb?
    return
  end

  at_exit { perform_at_exit }
  @installed_at_exit = true
end


  








  

    .disable_autorun!  
  

  

    This method is for internal use only.

# File 'rspec-core/lib/rspec/core/runner.rb', line 136



def self.disable_autorun!
  @autorun_disabled = true

    .handle_interrupt  
  

  

    This method is for internal use only.
  

  [ GitHub ]


  

  


# File 'rspec-core/lib/rspec/core/runner.rb', line 180



def self.handle_interrupt
  if RSpec.world.wants_to_quit
    exit!(1)
  else
    RSpec.world.wants_to_quit = true

    $stderr.puts(
      "\nRSpec is shutting down and will print the summary report... Interrupt again to force quit " \
      "(warning: at_exit hooks will be skipped if you force quit)."
    )
  end
end


  








  

    .invoke  
  



  

    

Runs the suite of specs and exits the process with an appropriate exit code.


  



  [ GitHub ]


  

  


# File 'rspec-core/lib/rspec/core/runner.rb', line 43



def self.invoke
  disable_autorun!
  status = run(ARGV, $stderr, $stdout).to_i
  exit(status) if status != 0
end


  








  

    .perform_at_exit  
  

  

    This method is for internal use only.
  

  [ GitHub ]


  

  


# File 'rspec-core/lib/rspec/core/runner.rb', line 29



def self.perform_at_exit
  # Don't bother running any specs and just let the program terminate
  # if we got here due to an unrescued exception (anything other than
  # SystemExit, which is raised when somebody calls Kernel#exit).
  return unless $!.nil? || $!.is_a?(SystemExit)

  # We got here because either the end of the program was reached or
  # somebody called Kernel#exit. Run the specs and then override any
  # existing exit status with RSpec's exit status if any specs failed.
  invoke
end


  








  

    .run(args, err = $stderr, out = $stdout)  ⇒ Fixnum 
  



  

    

Run a suite of ::RSpec examples. Does not exit.



This is used internally by ::RSpec to run a suite, but is available for use by any other automation tool.



If you want to run this multiple times in the same process, and you want files like ‘spec_helper.rb` to be reloaded, be sure to load load instead of require.


  





  
Parameters:


    
  
  • 
    args
    (Array)

    • 



Returns:


    
  
  • 
    (Fixnum)
—    
    

    exit status code. 0 if all specs passed, or the configured failure exit code (1 by default) if specs failed.
