Class Method Details

+ (void) 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.

  at_exit do
    # 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).
    next unless $!.nil? || $!.kind_of?(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
  @installed_at_exit = true
end

+ (void) invoke

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

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

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

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)

    command-line-supported arguments

  • err (IO) (defaults to: $stderr)

    error stream

  • out (IO) (defaults to: $stdout)

    output stream

Returns:

  • (Fixnum)

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