spinach vs cucumber for BDD in rails

Question

I am starting on BDD. Was wondering which would be better to start with Cucumber or Spinach. My impression is that Spinach is new off the block. Look here

Which one shou

Answer 1

For some context, I've been a long time user of Cucumber, but always wished it was Spinach since day one. I'm switching all my projects to Spinach despite its shortcomings because it uses the new, hot-off-the-block PORO technique (Plain Old Ruby Objects ;). Now I can expand my steps however I want, because it's just Ruby.

To answer your question, as of this writing:

1. Support across the board.

Cucumber

Spinach is still developing some features, including 'Background' blocks, and I'm currently trying to get it to recognize tables.

1. Flexibility of use

Spinach

Cucumber encourages bad step design from the start, IMO. If you create feature-specific steps, you'll trip over them later, and if you create reusable global steps, your feature definitions will be long, generic, and boring to read. I've heard people claim they can walk a balance successfully and be just specific enough but still have reusable steps; I consider myself well versed enough that if I can't do it reliably, it's too hard.

1. Third party tool and APIs integration

Cucumber, assuming the bullet point could be interpreted as community.

If it's really "third party tools and API integration" you're after, Spinach supports capybara and rspec, which is most of what you're after. Cucumber has 3rd party reusable step libraries, but as noted in my earlier point, I think this is bad. In regard to 3rd party & integrations, even if it's not there yet, your really can't get any better than plain old ruby objects.

Where does capybara fit into the picture

Capybara is your test interface to your site, aka a testing mouse & keyboard. You could start it up in a console and drive your app, but that'd get repetitive. Cucumber/Spinach (or rspec/test-unit/minitest) all could use capybara to automate testing your app. People prefer Cucumber/Spinach because they help you step out of the code for a bit to think like a user.

Overall, you'd probably be best off getting an rspec/cucumber book and doing what it says. Just be aware that testing takes a while to get good at, so don't stop there. Maybe check out Spinach somewhere in the process; if you like Cucumber, you might find you'll really like Spinach.
