assert_system_exit(*exp) { || ... } click to toggle source

like assert raises, but if it does raise, it checks status NOTE: this does not ensure the exception is raised

# File test/support/assert_helpers.rb, line 31
def assert_system_exit *exp
  msg = "#{exp.pop}.\n" if String === exp.last
  status = exp.first

  begin
    yield
  rescue SystemExit => e
    assert_equal status, e.status {
      exception_details(e, "#{msg}#{mu_pp(exp)} exception expected, not")
    } if status
    return true
  end
  flunk "#{msg}#{mu_pp(exp)} SystemExit expected but nothing was raised."
