Ruby – Reuse Cucumber steps


I want to reuse some Cucumber steps but can't seem to find the right way.

I want to write a step like:

Given /^I login with (.*) credentials$/ |type|
  # do stuff with type being one of "invalid" or "valid"

But then have another step like:

Given /^I login successfully$
  # call "Given I login with valid credentials"

So in testing user authentication I can use the former, but most other places, I can use the latter, and not actually have to repro code.

Is there a way to call that other step, or do I just put the logic in a helper method, and call said method from each task (basically a method extraction refactoring, which, after reading my question makes me believe that's actually the best way anyway)?

Note that the method for calling steps within steps has changed in recent versions of cucumber, which you'll see if you get an error like "WARNING: Using 'Given/When/Then' in step definitions is deprecated, use 'step' to call other steps instead:/path/to/step_definitions/foo_steps.rb:631:in `block in ' ". See the cucumber wiki for details.

The gist of the change is that you should now use the step or steps methods.

When /^I make all my stuff shiny$/
  step "I polish my first thing"

When /^I make all my stuff shiny$/
  steps %Q{
    When I polish my first thing
    When I shine my second thing
