Cucumber-js: How to use tag in my function scenario Cucumber.js?

Created on 8 Dec 2015 · 5Comments · Source: cucumber/cucumber-js

Hi,

How to know the scenario that calls my function ? How to use the tags in my function scenario ?

Actually I have one scenario :

Feature: create module feature
  As a admin
  I want to use create module

  @createModule
  Given I am logged as 'ADMIN'
    And I am on "/admin/create"
   Then The "book_id" field should be empty

I would like to use my tag @createModule in my function Then :

this.Then(/^The "?([^"]*)"? field should be empty$/, function (el) {

    if (myModule === @createModule) {
        ...
    } else if {
        ...
    }

    return main_po.checkIsEmptyElement(this, el);
});

I would like to get my tag @createModule, to specify the scenario called, or other alternative, I would like to know what scenarios call my function.

Solved :

I added :

this.Before(function (scenario, callback) {
    var tags = scenario.getTags();

    this.current_module = tags[0].getName();

    callback();
});

and my function :

this.Then(/^The "?([^"]*)"? field should be empty$/, function (el) {

    if (this.current_module === @createModule) {
        ...
    } else if {
        ...
    }

    return main_po.checkIsEmptyElement(this, el);
});

Tags are used for choosing what scenarios to run when executing cucumber-js (see the README). Currently steps don't have any way of telling what scenario they are currently being run for. All steps under a scenario will share a world instance (accessed through this in the step definition).

@jechazelle thanks for posting your solution I need the same functionality for a different use case :)

In cucumber-js 3.2.1 I to use

Before({timeout: 20000}, async function(testCase) {
  this.tags = testCase.pickle.tags.map((tag) => tag.name);`
  ...
}

The reason I'm using it is because a particular step implementation is failing for a known subset of scenarios, so I've created a non-critical defect ticket in our tracking system, tagged the failing scenarios with the ticket# and then added logic in the step implementation to return 'pending' if this.tags contains the ticket number.

This allows out build to go back to green, while the powers that be decide if they want to fix the defect or not.
