rspec

response.should be_successful or response.should be_missing are nice but not enough. In too many cases I'm looking for response codes that are neither 200 nor 404.

So how about adding all the status symbols as tests methods?

Controller:

head :unauthorized

Spec:

response.should be_unauthorized

Controller:

head :gone

Spec:

response.should be_gone

And so forth. This code will do it for anything using controller (TestResponse) and integration (CgiResponse) tests:

module ActionController
  # TestResponse for functional, CgiResponse for integration.
  class AbstractResponse
    StatusCodes::SYMBOL_TO_STATUS_CODE.each do |symbol, code|
      define_method("#{symbol}?") { self.response_code == code } unless
instance_methods.include?("#{symbol}?")
    end
  end
end
