You're basically writing gherkin scripts within gherkin (they're hidden within JS step definitions, but that's a detail that makes it even worse from a maintenance POV). @inf3rno if you want to reuse code in stepdefs, move the body of the stepdef to a regular javascript function and reuse that. An annotation followed by the pattern is used to link the Step Definition to all the matching Steps , and the code is what Cucumber will execute when it sees a Gherkin Step .

So sad this won't fix, as @cono says: invoking one single step is almost useles, real cases are more complex operations. Thank you Matt. Runtime.getSupportCodeLibrary returns a new instance, Access step inside a step in cucumberjs-Protractor. As for the binding issue, you should define those functions as methods on your World: Also, please note that synchronous step definitions are supported by Cucumber.js 0.5+: @inf3rno step definitions are a thin translation layer between plain english and JS code. @aslakhellesoy Then how to chain the step calls? Am pondering whether this is a useful extension to better describe long user journeys through the system and would prefer to work with any prior art. }); That doesn't work very well since x_is_something would have called the If you want to combine several actions into one step, extract individual (helper) methods and call these methods from your step definition. Unfortunately, this is the most wanted feature right now on Cucumber.js.. As I understand it, many people consider step definitions as methods or functions.The way I see it, they're mappings between some fluent language sentences and pieces of programming language code, … this.y = y; I totally agree with you Matt. In CukeTest you can not only generate code and jump to it, but also jump from the step definition code to the corresponding step: Step 5. We’ll occasionally send you account related emails.
