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

Run a suite of RSpec examples.

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 - an array of command-line-supported arguments

  • err - error stream (Default: $stderr)

  • out - output stream (Default: $stdout)

#### Returns

  • Fixnum - exit status code (0/1)
