It should be part of 0.4. You can still define users in a background and iterate over them in your When step. This includes both code snippets embedded in the card text and code that is included as a file attachment. and created separate step definition files for feature specific steps. @inf3rno if you want to reuse code in stepdefs, move the body of the stepdef to a regular javascript function and reuse that.

Step Definitions are also known as Glue Code. console.log('x', x); See cucumber/cucumber#68. y_is_something(8, cb); this.y = y; That doesn't work very well since x_is_something would have called the callback before y_is_something has chance to finish its work.

As we know, in Cucumber.js the default unimplemented code stub returns a string "pending", which is the code generated by default. What @mattwynne suggested (add a gherkin feature which supports code reusability): What @aslakhellesoy suggested (extracting the duplicated code to js functions): I still don't understand why do we need another unnecessary abstraction level, do you have any explanation? Calling steps from stepdefs is one of those features I wish I never added to Cucumber(-Ruby), because it provides so much rope for people to hang themselves with. The decision on how to split is the same as when you decide which functionality goes in which class. @jbpros, I am going to use your solution since I am used to programming in Java and not worrying about promises :), Did anyone ever come up with an extension to cucumber for defining steps in terms of other steps?
