Class Method Details

.autorunvoid

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.

    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

.invokevoid

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

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