Limiting capture group options in Cucumber for dynamic parameters: A comprehensive guide

Currently, I am working on creating a test automation step-definition using Cucumber and WebdriverJS. The scenario involves validating certain actions based on different service methods.

Scenario Outline : Validate functionality for different service methods
  Given I have a <Service Method> for the test store
  Then validate that something exists
 
  Example :

  |Service Method|
  |Carryout      |
  |Delivery      |
  |Dine-in       |

As part of this process, I need to map the cucumber step to an auto-generated step-definition file, which looks like this:

this.Given(/^I have a (.*) order$/, function (serviceMethod) {}

However, I want to ensure that the function only executes if the cucumber parameter matches one of these values: carryout, delivery, dine-in. I attempted to achieve this by modifying the regex in the following way, but it seems to have caused issues with mapping to the nodeJS step-definition:

this.Given(/^I have a (.*) (carryout|delivery|dine-in)? order$/, function (serviceMethod) {}

If anyone has any suggestions on how to resolve this issue, I would greatly appreciate the help. Thank you!

Answer №1

If you find yourself in need of one of these particular types of orders, you can expedite the process by confirming its presence and specifying the relevant container style.

/^(?=.* (takeout|delivery|dine-in) )I possess a.*order$/

The first group denotes the classification of the order.

Answer №2

When I create a step-definition to handle different types of food orders (carryout, delivery, dine-in) using this syntax: <code>this.Given(/^I have a (carryout|delivery|dine-in) order$/, function (serviceMethod) {}

I am pleased to announce that the above step-definition has successfully executed for me.
