I want to start using BDD for one of my Node.js projects. Looking at the Node.js wiki, I find at least 3 modules: Cucumber, gherkin, and cucumis that all support the gherkin language. Which ones do you recommend?

Cucumber.js is the official port of Cucumber. It is supported by the Cucumber community and aims at being as compatible as possible with its brothers (Cucumber-ruby, Cucumber-jvm). It's strongly tested through the same gherkin feature suite as Cucumber-ruby and Cucumber-jvm.
Cucumber.js is supported in both Node.js and browser environments. It uses the official Gherkin parser, just like Cucumber-ruby.
I'm not really familiar with Cucumis but the only advantage of it over Cucumber.js is that it supports parallel scenario execution. We are considering such a feature on Cucumber.js but it needs some more thinking as it has implications end-users must fully understand.
The gherkin NPM package is not usable as is, it's only supplying the gherkin parser.
The Cucumber.js's README displays a development status table that can help you decide wether it's ready for your needs or not.
If you need support with Cucumber.js, shout in #cucumber on Freenode, ping us on Twitter or write to the Cukes list.
If you're interested, Cucumber.js will be presented during the CukeUp! conference in London on April 4th.

Thanks. That's exactly the information I was looking for. – abendigo Mar 21 '12 at 13:23

Using cucumber.js, can I generate junit style XML files? – abendigo Mar 21 '12 at 18:56

There is no such formatters yet. But this can be added, given we have the XML schema available. – jbpros Mar 21 '12 at 22:54

You could also look at Yadda. It's a BDD framework with a Gherkin-like syntax (not 100% compatible) which piggybacks on your existing test runner (e.g. mocha, jasmine, casper, qunit). The reports are therefore formatted in the same way as your unit tests.
