Is there a “for each” or equivalent syntax for Gherkin/Cucumber?

 

Questions


Is there any equivalent “for each” statement for Gherkin? In the following scenario, the page I am testing has multiple date fields that I’d like to run the same test examples on.

Here is the scenario that I would like to model.

Scenario Outline: Modify precision values for date controls

Given I have just added a record

 When I select <precision>

  And I select <value>

 Then <date> displays in the <date type> field

Examples:

  | date type | precision | value           | date                     |

  | Date 1    | Unknown   | N/A             | "Unknown"                | 

  | Date 1    | Year      | <current year>  | <current year>           |

  | Date 1    | Month     | <current month> | <current month, year>    |

  | Date 1    | Day       | <current day>   | <current month/day/year> | 

  | Date 2    | Unknown   | N/A             | "Unknown"                | 

  | Date 2    | Year      | <current year>  | <current year>           | 

  | Date 2    | Month     | <current month> | <current month, year>    | 

  | Date 2    | Day       | <current day>   | <current month/day/year> | 

Suppose there are 5 date type fields on the same page. It seems unnecessary to have to copy/psate 12 more rows in the table to cover Date 3 – Date 5. That’s why I was wondering if there is a “for each” equivalent so that I can perform the same examples for each date type without having to explicitly show that in the Examples table. Or perhaps there is a different way I could structure the scenario?

Thanks for any assistance you can provide!

Answer

Nope, cucumber is not designed with looping in mind. Cucumber’s scope is to allow defining application expectancies from a user perspective. And since real users don’t “loop”, it doesn’t make sense to have it implemented in cucumber.

What can be done, programatically speaking, is to write a program that generates the same cucumber scripts for every combination in your application.
