Node.js BDD. Cucumber, gherkin, or cucumis?

Question

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?

Answer 1

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.
